Manual and ventilator hyperinflation parameters used by intensive care physiotherapists in Sri Lanka: An online survey. PLoS One 2024; 19:e0297880. [PMID: 38768181 PMCID: PMC11104683 DOI: 10.1371/journal.pone.0297880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 01/03/2024] [Indexed: 05/22/2024] Open
Abstract
INTRODUCTION Hyperinflation is a common procedure to clear secretion, increase lung compliance and enhance oxygenation in mechanically ventilated patients. Hyperinflation can be provided as manual hyperinflation (MHI) or ventilator hyperinflation (VHI), where outcomes depend upon the methods of application. Hence it is crucial to assess the application of techniques employed in Sri Lanka due to observed variations from recommended practices. OBJECTIVE This study is aimed to evaluate the application and parameters used for MHI and VHI by physiotherapists in intensive care units (ICUs) in Sri Lanka. METHODOLOGY An online survey was conducted among physiotherapists who are working in ICUs in Sri Lanka using WhatsApp groups and other social media platforms. RESULTS A total of 96 physiotherapists responded. The survey comprised of three sections to obtain information about socio-demographic data, MHI practices and VHI practices. Most of the respondents (47%) worked in general hospitals and 74% of participants had a bachelor's degree in physiotherapy; 31.3% had 3-6 years of experience; 93.8% used hyperinflation, and 78.9% used MHI. MHI was performed routinely and as needed to treat low oxygen levels, abnormal breath sounds, and per physician orders while avoiding contraindications. Self-inflation bags are frequently used for MHI (40.6%). Only a few participants (26%) used a manometer or tracked PIP. In addition to the supine position, some participants (37.5%) used the side-lying position. Most physiotherapists followed the recommended MHI technique: slow squeeze (57.3%), inspiratory pause (45.8%), and quick release (70.8%). VHI was practised by 19.8%, with medical approval and it was frequently performed by medical staff compared to physiotherapists. Treatment time, number of breaths, and patient positioning varied, and parameters were not well-defined. CONCLUSION The study found that MHI was not applied with the recommended PIP, and VHI parameters were not identified. The study indicates a need to educate physiotherapists about current VHI and MHI practice guidelines.

Diagnostics (Basel) 2024; 14:398. [PMID: 38396437 PMCID: PMC10888003 DOI: 10.3390/diagnostics14040398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 01/22/2024] [Accepted: 02/10/2024] [Indexed: 02/25/2024] Open
Abstract
Weaning patients from mechanical ventilation (MV) is a complex process that may result in either success or failure. The use of ultrasound at the bedside to assess organs may help to identify the underlying mechanisms that could lead to weaning failure and enable proactive measures to minimize extubation failure. Moreover, ultrasound could be used to accurately identify pulmonary diseases, which may be responsive to respiratory physiotherapy, as well as monitor the effectiveness of physiotherapists' interventions. This article provides a comprehensive review of the role of ultrasonography during the weaning process in critically ill patients.

Pulmonary expansion manoeuvres compared to usual care on ventilatory mechanics, oxygenation, length of mechanical ventilation and hospital stay, extubation, atelectasis, and mortality of patients in mechanical ventilation: A randomized clinical trial. PLoS One 2023; 18:e0295775. [PMID: 38079432 PMCID: PMC10712844 DOI: 10.1371/journal.pone.0295775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 11/10/2023] [Indexed: 12/18/2023] Open
Abstract
Pulmonary expansion manoeuvres are therapeutic techniques used to prevent and reverse atelectasis; however, no randomized controlled trials have provided evidence supporting the use of this intervention among individuals on mechanical ventilation. OBJECTIVE To evaluate the effects of chest compression-decompression and chest block manoeuvres compared to usual care among patients on mechanical ventilation. METHODS The current study was a randomized clinical trial of adult subjects on mechanical ventilation for 12 to 48 hours. The control group received usual care (passive or active mobilization, manoeuvres for airway clearance and tracheal aspiration). The intervention group received usual care plus two lung expansion manoeuvres, i.e., chest decompression and chest block, while remaining on mechanical ventilation. Assessments were performed before and after usual care, immediately after the intervention and 30 minutes after the intervention. The primary outcome was static compliance. The secondary outcomes were the incidence of atelectasis, dynamic compliance, airway resistance, driving pressure, oxygenation, duration of mechanical ventilation, extubation success, length of hospital and ICU stay, and mortality. RESULTS Fifty-one participants (67±15 years old, 53% men, 26 in the control group and 25 in the intervention group) were evaluated. No differences in static compliance were observed between groups (intervention minus control) before and after expansion manoeuvres [3.64 ml/cmH2O (95% CI: -0.36-7.65, p = 0.074)]. Peripheral oxygen saturation differed between groups before and after expansion manoeuvres, with more favourable outcome observed in the control group [-1.04% (95% CI: -1.94 --0.14), p = 0.027]. No differences were found in other outcomes. CONCLUSION Chest compression-decompression and chest block manoeuvres did not improve ventilatory mechanics, the incidence of atelectasis, oxygenation, the duration of mechanical ventilation, the length of stay in the ICU and hospital, or mortality in individuals on mechanical ventilation. The findings of this study can be valuable for guiding evidence-based clinical practice and developing a therapeutic approach that provides real benefits for this population.

Abstract
BACKGROUND Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia. This is an update of a review first published in 2010 and updated in 2013. OBJECTIVES To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults. SEARCH METHODS We updated our searches in the following databases to May 2022: the Cochrane Central Register of Controlled Trials (CENTRAL) via OvidSP, MEDLINE via OvidSP (from 1966), Embase via embase.com (from 1974), Physiotherapy Evidence Database (PEDro) (from 1929), CINAHL via EBSCO (from 2009), and the Chinese Biomedical Literature Database (CBM) (from 1978). SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs assessing the efficacy of chest physiotherapy for treating pneumonia in adults. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included two new trials in this update (540 participants), for a total of eight RCTs (974 participants). Four RCTs were conducted in the United States, two in Sweden, one in China, and one in the United Kingdom. The studies looked at five types of chest physiotherapy: conventional chest physiotherapy; osteopathic manipulative treatment (OMT, which includes paraspinal inhibition, rib raising, and myofascial release); active cycle of breathing techniques (which includes active breathing control, thoracic expansion exercises, and forced expiration techniques); positive expiratory pressure; and high-frequency chest wall oscillation. We assessed four trials as at unclear risk of bias and four trials as at high risk of bias. Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving mortality, but the certainty of evidence is very low (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.15 to 7.13; 2 trials, 225 participants; I² = 0%). OMT (versus placebo) may have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.43, 95% CI 0.12 to 1.50; 3 trials, 327 participants; I² = 0%). Similarly, high-frequency chest wall oscillation (versus no physiotherapy) may also have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.75, 95% CI 0.17 to 3.29; 1 trial, 286 participants). Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.93, 95% CI 0.56 to 1.55; 2 trials, 225 participants; I² = 85%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.60, 95% CI 0.29 to 1.23; 1 trial, 32 participants). OMT (versus placebo) may improve cure rate, but the certainty of evidence is very low (RR 1.59, 95% CI 1.01 to 2.51; 2 trials, 79 participants; I² = 0%). OMT (versus placebo) may have little to no effect on mean duration of hospital stay, but the certainty of evidence is very low (mean difference (MD) -1.08 days, 95% CI -2.39 to 0.23; 3 trials, 333 participants; I² = 50%). Conventional chest physiotherapy (versus no physiotherapy, MD 0.7 days, 95% CI -1.39 to 2.79; 1 trial, 54 participants) and active cycle of breathing techniques (versus no physiotherapy, MD 1.4 days, 95% CI -0.69 to 3.49; 1 trial, 32 participants) may also have little to no effect on duration of hospital stay, but the certainty of evidence is very low. Positive expiratory pressure (versus no physiotherapy) may reduce the mean duration of hospital stay by 1.4 days, but the certainty of evidence is very low (MD -1.4 days, 95% CI -2.77 to -0.03; 1 trial, 98 participants). Positive expiratory pressure (versus no physiotherapy) may reduce the duration of fever by 0.7 days, but the certainty of evidence is very low (MD -0.7 days, 95% CI -1.36 to -0.04; 1 trial, 98 participants). Conventional chest physiotherapy (versus no physiotherapy, MD 0.4 days, 95% CI -1.01 to 1.81; 1 trial, 54 participants) and OMT (versus placebo, MD 0.6 days, 95% CI -1.60 to 2.80; 1 trial, 21 participants) may have little to no effect on duration of fever, but the certainty of evidence is very low. OMT (versus placebo) may have little to no effect on the mean duration of total antibiotic therapy, but the certainty of evidence is very low (MD -1.07 days, 95% CI -2.37 to 0.23; 3 trials, 333 participants; I² = 61%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on duration of total antibiotic therapy, but the certainty of evidence is very low (MD 0.2 days, 95% CI -4.39 to 4.69; 1 trial, 32 participants). High-frequency chest wall oscillation plus fibrobronchoscope alveolar lavage (versus fibrobronchoscope alveolar lavage alone) may reduce the MD of intensive care unit (ICU) stay by 3.8 days (MD -3.8 days, 95% CI -5.00 to -2.60; 1 trial, 286 participants) and the MD of mechanical ventilation by three days (MD -3 days, 95% CI -3.68 to -2.32; 1 trial, 286 participants), but the certainty of evidence is very low. One trial reported transient muscle tenderness emerging after OMT in two participants. In another trial, three serious adverse events led to early withdrawal after OMT. One trial reported no adverse events after positive expiratory pressure treatment. Limitations of this review were the small sample size and unclear or high risk of bias of the included trials. AUTHORS' CONCLUSIONS The inclusion of two new trials in this update did not change the main conclusions of the original review. The current evidence is very uncertain about the effect of chest physiotherapy on improving mortality and cure rate in adults with pneumonia. Some physiotherapies may slightly shorten hospital stays, fever duration, and ICU stays, as well as mechanical ventilation. However, all of these findings are based on very low certainty evidence and need to be further validated.

Immediate effects of manual hyperinflation on cardiorespiratory function and sputum clearance in mechanically ventilated pediatric patients: A randomized crossover trial. Hong Kong Physiother J 2021; 42:15-22.

Abstract
Background: In developing countries, lower respiratory tract infection is a major cause of death in children, with severely ill patients being admitted to the critical-care unit. While physical therapists commonly use the manual hyperinflation (MHI) technique for secretion mass clearance in critical-care patients, its efficacy has not been determined in pediatric patients. Objective: This study investigated the effects of MHI on secretion mass clearance and cardiorespiratory responses in pediatric patients undergoing mechanical ventilation. Methods: A total of 12 intubated and mechanically ventilated pediatric patients were included in this study. At the same time of the day, the patients received two randomly ordered physical therapy treatments (MHI with suction and suction alone) from a trained physical therapist, with a washout period of 4 h provided between interventions. Results: The MHI treatment increased the tidal volume [Vt; 1.2 mL/kg (95% CI, 0.8–1.5)] and static lung compliance [Cstat; 3.7 mL/cmH2O (95% CI, 2.6–4.8)] immediately post-intervention compared with the baseline (p<0.05). Moreover, the MHI with suction induced higher Vt [1.4 mL/kg (95% CI, 0.8–2.1)] and Cstat [3.4 mL/cmH2O (95% CI, 2.1–4.7)] compared with the suction-alone intervention. In addition, the secretion mass [0.7 g (95% CI, 0.6–0.8)] was greater in MHI with suction compared with suction alone (p<0.05). However, there was no difference in peak inspiratory pressure, mean airway pressure, respiratory rate, heart rate, blood pressure, mean arterial blood pressure or oxygen saturation (p>0.05) between interventions. Conclusions: MHI can improve Vt, Cstat and secretion mass without inducing adverse hemodynamic effects upon the pediatric patients requiring mechanical ventilation.

Abstract
Purpose: A systematic review was conducted to investigate the effect of respiratory physiotherapy on mortality, quality of life, functional recovery, intensive care length of stay, duration of ventilation, oxygenation, secretion clearance, and pulmonary mechanics for invasively ventilated adults with pneumonia. Method: Five databases were searched for randomized trials published between January 1995 and November 2018. Study quality was assessed using a standardized Joanna Briggs Institute critical appraisal tool, and Review Manager software was used to pool the studies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the level of certainty of the evidence. Results: A total of 14 studies of moderate quality included 251 subjects with pneumonia. Eight studies were pooled for meta-analysis. Interventions that increased inspiratory volume appeared to benefit secretion clearance by nearly 2 grams (mean difference [MD] 1.97; 95% CI: 0.80, 3.14; very low GRADE evidence) and increase static lung compliance immediately after treatment by more than 5 millilitres/centimetre H20 (MD 5.40 mL/cm H2O; 95% CI: 2.37, 8.43; very low GRADE evidence) or by more than 6 millilitres/centimetre H2O after a 20- to 30-minute delay (MD 6.86 mL/cm H2O; 95% CI: 2.86, 10.86; very low GRADE evidence). No adverse events were found. Conclusions: Respiratory physiotherapy that increases tidal volume may benefit secretion clearance and lung compliance in invasively ventilated adults with pneumonia, but its impact on other outcomes, including mortality, length of stay, and other patient-centred outcomes, is unclear, and further research is required.

Abstract
OBJECTIVES To conduct multidisciplinary peer-review of expert consensus statements for respiratory physiotherapy for invasively ventilated adults with community-acquired pneumonia, to determine clinical acceptability for development into a clinical practice guideline. RESEARCH METHODOLOGY A qualitative study was undertaken using focus groups (n = 3) conducted with clinician representatives from five Australian states. Participants were senior intensive care physiotherapists, nurses and consultants. Thematic analysis was used, with a deductive approach to confirm clinical validity, and inductive analysis to identify new themes relevant to the application of the 38 statements into practice. SETTING Adult intensive care. FINDINGS Senior intensive care clinicians from physiotherapy (n = 16), medicine (n = 6) and nursing (n = 4) participated. All concurred that the consensus statements added valuable guidance to practice; twenty-nine (76%) were deemed relevant and applicable for the intensive care setting without amendment, with modifications suggested for remaining nine statements to enhance utility. Overarching themes of patient safety, teamwork and communication and culture were identified as factors influencing clinical application. Cultural differences in practice, particularly related to patient positioning, was evident between jurisdictions. Participants raised practicality and safety concerns for two statements related to the use of head-down patient positioning. CONCLUSION Multidisciplinary peer-review established clinical validity of expert consensus statements for implementation with invasively ventilated adults with community-acquired pneumonia.

Abstract
Background Despite unclear evidence of effectiveness or safety, airway clearance therapy (ACT) is frequently performed in infants and children with acute pulmonary disease. Objectives The aim of this review was to critically synthesise published evidence, expert opinion and pathophysiological principles to describe the indications, effects, precautions and application of commonly used ACT modalities for managing infants and children with acute pulmonary disease. Method A comprehensive narrative review of published literature was conducted. Articles describing paediatric populations were prioritised, but adult and animal studies were also considered where appropriate. Results There is a dearth of high-level evidence supporting the use of ACT in acutely ill infants and children. Conversely, studies have highlighted the lack of effect of different modalities for a variety of conditions, and in some cases serious associated complications have been reported.Airway clearance therapy may be considered when there is retention of pulmonary secretions, and the consequential airway obstruction impacts either acutely on respiratory mechanics and gaseous exchange and/or has the potential for long-term adverse sequelae [a condition that is the consequence of a previous disease or injury]. However, it should not be considered a routine intervention. Conclusion Airway clearance therapy should not be performed routinely in children admitted to hospital with acute respiratory conditions. Patients should be clinically assessed and treatment planned according to individual presentation, in those with signs and symptoms that are potentially amenable to ACT. Clinical implications This review can serve as a guide for physiotherapists in the respiratory management of children with acute respiratory illness, as well as identifying areas for clinical research.

Abstract
This study evaluated the ventilatory and haemodynamic effects of the mechanical insufflator-exsufflator (MI-E) in critically ill patients. Sixteen mechanically ventilated patients performed three protocols: MI-E (-30/+30 cmH2O) plus endotracheal suctioning; 50S: MI-E (-50/+50 cmH2O) plus endotracheal suctioning; and isolated endotracheal suctioning (IES). The protocols were applied randomly in all subjects, with 3 -h intervals in between. Peak airway pressure (Ppeak), plateau pressure (Pplat), airway resistance (Raw), static compliance (Cst), heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure, peripheral oxygen saturation (SpO2) and amount of removed secretions were evaluated before (PRE), immediately after (POST) and 10 min after (10' POST) each protocol. The 50S protocol reduced Ppeak and Raw and increased Cst immediately after its application. Moreover, this protocol provided the largest amount of removed secretions and held SBP, DBP and SpO2 at basal values. The MI-E at high pressures promotes benefits to respiratory mechanics, is more effective in removing pulmonary secretions and it does not lead to hemodynamic repercussions.

van der Lee L, Hill AM, Patman S. Expert consensus for respiratory physiotherapy management of mechanically ventilated adults with community-acquired pneumonia: A Delphi study. J Eval Clin Pract 2019; 25:230-243. [PMID: 30565374 DOI: 10.1111/jep.13077] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Revised: 10/29/2018] [Accepted: 10/29/2018] [Indexed: 01/04/2023]
Abstract
RATIONALE AND AIMS Patients with community-acquired pneumonia (CAP) are frequently admitted to an intensive care unit. Physiotherapy may be provided to optimize respiratory function; however, there is significant variability in clinical practice and limited research directing best practice for this cohort. This study aimed to determine expert consensus for best physiotherapy practice for invasively ventilated adults with CAP. METHOD A modified Delphi technique involved an international expert panel completing three rounds of an online questionnaire. The initial 35-statement questionnaire, based on a systematic literature review and survey of current clinical practice, covered physiotherapy assessment and treatment of intubated patients with CAP. Quantitative data using Likert scales determined level of agreement, with qualitative data collected through open-ended responses. Consensus threshold was set a priori at 70%. Items not achieving consensus were modified and new items added based on themes from qualitative data. Quantitative data were analysed descriptively, with thematic analysis used on qualitative data. RESULTS The panel comprised 29 international clinical and academic experts in critical care physiotherapy. Response rate was more than 95% for each round. Outcome achieved was 38 consensus statements covering assessment and treatment, with 28 statements (74%) providing consensus on recommended clinical practice, two consensus disagreement statements (7%) for what practice is not recommended, and eight statements (21%) indicating which treatments may be beneficial. CONCLUSION Expert consensus regarding physiotherapy for intubated adults with CAP patients provides an evidence-based approach to guide clinical practice. The consensus statements can also be used to guide research evaluating physiotherapy interventions for patients with CAP.

Abstract
PURPOSE This scoping review summarizes the literature on the safety and effectiveness of physiotherapy interventions in patients with neurological and/or traumatic injuries in the intensive care unit (ICU), identifies literature gaps and provides recommendations for future research. MATERIALS AND METHODS We searched five databases from inception to June 2, 2018. We included published retrospective studies, case studies, observation and randomized controlled trials describing physiotherapy interventions in ICU patients with neurotrauma injuries. Two reviewers reviewed the databases and independently screened English articles for eligibility. Data extracted included purpose, study design, population (s), outcome measures, interventions and results. Thematic analysis and descriptive numerical summaries are presented by intervention type. RESULTS 12,846 titles were screened and 72 met the inclusion criteria. Most of the studies were observational studies (44 (61.1%)) and RCTs (14 (19.4%)). Early mobilization, electrical stimulation, range of motion, and chest physiotherapy techniques were the most common interventions in the literature. Physiotherapy interventions were found to be safe with few adverse events. CONCLUSIONS Gaps in the literature suggest that future studies require assessment of long term functional outcomes and quality of life, examination of homogenous populations and more robust methodologies including clinical trials and larger samples.

Abstract
QUESTION In intubated adult patients receiving mechanical ventilation, does multimodality respiratory physiotherapy prevent ventilator-associated pneumonia, shorten length of intensive care unit (ICU) stay, and reduce mortality? DESIGN A systematic review with meta-analysis of randomised controlled trials. PARTICIPANTS Intubated adult patients undergoing mechanical ventilation who were admitted to an intensive care unit. INTERVENTION More than two respiratory physiotherapy techniques such as positioning or postural drainage, manual hyperinflation, vibration, rib springing, and suctioning. OUTCOMES MEASURES Incidence of ventilator-associated pneumonia (VAP), duration of ICU stay, and mortality. RESULTS Five trials were included in the meta-analysis. Random-effects models were used to calculate pooled weighted mean difference (WMD) for length of ICU stay and pooled risk ratio (RR) for incidence of VAP, and fixed-effects model was used to calculate pooled RR for mortality. The effect on the incidence of VAP was unclear (RR 0.73 in favour of multimodality respiratory physiotherapy, 95% CI 0.38 to 1.07). The effect on length of stay was also unclear (WMD -0.33days shorter with multimodality respiratory physiotherapy, 95% CI -2.31 to 1.66). However, multimodality respiratory physiotherapy significantly reduced mortality (RR 0.75, 95% CI 0.58 to 0.92). CONCLUSION Multimodality respiratory physiotherapy appeared to reduce mortality in ICU patients. It was unclear whether this occurred via a reduction in the incidence of VAP and/or length of stay because the available data provided very imprecise estimates of the effect of multimodality respiratory physiotherapy on these outcomes. These very imprecise estimates include the possibility of very worthwhile effects on VAP incidence and length of ICU stay; therefore, these outcomes should be the focus of further investigation in rigorous trials.

ENFERMERIA INTENSIVA 2018; 29:168-181.

Abstract
INTRODUCTION AND AIMS Patients in intensive care unit are susceptible to complications due to different causes (underlying disease, immobilisation, infection risk…) The current main intervention in order to prevent these complications is respiratory physiotherapy, a common practice for nurses on a daily basis. Therefore, we decided to carry out this bibliographic review to describe the most efficient respiratory physiotherapy methods for the prevention and treatment of lung complications in patients in intensive care, taking into account the differences between intubated and non-intubated patients. METHODOLOGY The bibliographic narrative review was carried out on literature available in Pubmed, Cinahl and Cochrane Library. The established limits were language, evidence over the last 15 years and age. RESULTS Techniques involving lung expansion, cough, vibration, percussion, postural drainage, incentive inspirometry and oscillatory and non-oscillatory systems are controversial regarding their efficacy as respiratory physiotherapy methods. However, non-invasive mechanical ventilation shows clear benefits. In the case of intubated patients, manual hyperinflation and secretion aspirations are highly efficient methods for the prevention of the potential complications mentioned above. In this case, other RP methods showed no clear efficiency when used individually. DISCUSSION AND CONCLUSIONS Non-invasive mechanical ventilation (for non-intubated patients) and manual hyperinflation (for intubated patients) proved to be the respiratory physiotherapy methods with the best results. The other techniques are more controversial and the results are not so clear. In both types of patients this literature review suggests that combined therapy is the most efficient.

Abstract
INTRODUCTION Community acquired pneumonia (CAP) is a common reason for admission to an intensive care unit for intubation and mechanical ventilation, and results in high morbidity and mortality. The primary aim of the study was to investigate availability and provision of respiratory physiotherapy, outside of normal business hours, for intubated and mechanically ventilated adults with CAP in Australian hospitals. MATERIALS AND METHODS A cross-sectional, mixed methods online survey was conducted. Participants were senior intensive care unit physiotherapists from 88 public and private hospitals. Main outcome measures included presence and nature of an after-hours physiotherapy service and factors perceived to influence the need for after-hours respiratory physiotherapy intervention, when the service was available, for intubated adult patients with CAP. Data were also collected regarding respiratory intervention provided after-hours by other ICU professionals. RESULTS Response rate was 72% (n=75). An after-hours physiotherapy service was provided by n=31 (46%) hospitals and onsite after-hours physiotherapy presence was limited (22%), with a combination of onsite and on-call service reported by 19%. Treatment response (83%) was the most frequent factor for referring patients with CAP for after-hours physiotherapy intervention by the treating day-time physiotherapist. Nurses performing respiratory intervention (77%) was significantly associated with no available after-hours physiotherapy service (p=0.04). DISCUSSION Physiotherapy after-hours service in Australia is limited, therefore it is common for intubated patients with CAP not to receive any respiratory physiotherapy intervention outside of normal business hours. In the absence of an after-hours physiotherapist, nurses were most likely to perform after-hours respiratory intervention to intubated patients with CAP. CONCLUSION Further research is required to determine whether the frequency of respiratory physiotherapy intervention, including after-hours provision of treatment, influences outcomes for ICU patients intubated with pneumonia.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Community-acquired pneumonia (CAP) is a common cause for intensive care unit (ICU) admission resulting in high morbidity and mortality. There is a paucity of evidence regarding respiratory physiotherapy for intubated and mechanically ventilated patients with CAP, and anecdotally clinical practice is variable in this cohort. The aims of this study were to identify the degree of variability in physiotherapy practice for intubated adult patients with CAP and to explore ICU physiotherapist perceptions of current practice for this cohort and factors that influence physiotherapy treatment mode, duration, and frequency. METHOD A survey was developed based on common aspects of assessment, clinical rationale, and intervention for intubated and mechanically ventilated patients. Senior ICU physiotherapists across 88 Australian public and private hospitals were recruited. RESULTS The response rate was 72%. Respondents (n = 75) stated their main rationale for providing a respiratory intervention were improved airway clearance (98%, n = 60/61), alveolar recruitment (74%, n = 45/61), and gas exchange (33%, n = 20/61). Respondents estimated that average intervention lasted between 16 and 30 minutes (70% of respondents, n = 41/59) and would be delivered once (44%) or twice (44%) daily. Results indicated large variability in reported practice; however, trends existed regarding positioning in alternate side-lying (81%, n = 52/64) or affected lung uppermost (83%, n = 53/64) and use of hyperinflation techniques (81%, 52/64). Decisions regarding duration were reported to be based on sputum volume (95%), viscosity (93%) and purulence (88%), cough effectiveness (95%), chest X-ray (87%), and auscultation (84%). Sixty percent reported that workload and staffing affected intervention duration and frequency. Intervention time was more likely increased when there was greater staffing (P = .03). CONCLUSION Respiratory physiotherapy treatment varies for intubated patients with CAP. Further research is required to determine what is considered best practice for this patient population.

Abstract
Objective To evaluate the changes in ventilatory mechanics and hemodynamics that occur in
patients dependent on mechanical ventilation who are subjected to a standard
respiratory therapy protocol. Methods This experimental and prospective study was performed in two intensive care units,
in which patients dependent on mechanical ventilation for more than 48 hours were
consecutively enrolled and subjected to an established respiratory physiotherapy
protocol. Ventilatory variables (dynamic lung compliance, respiratory system
resistance, tidal volume, peak inspiratory pressure, respiratory rate, and oxygen
saturation) and hemodynamic variables (heart rate) were measured one hour before
(T-1), immediately after (T0) and one hour after
(T+1) applying the respiratory physiotherapy protocol. Results During the period of data collection, 104 patients were included in the study.
Regarding the ventilatory variables, an increase in dynamic lung compliance
(T-1 = 52.3 ± 16.1mL/cmH2O versus T0 =
65.1 ± 19.1mL/cmH2O; p < 0.001), tidal volume (T-1
= 550 ± 134mL versus T0 = 698 ± 155mL; p < 0.001), and
peripheral oxygen saturation (T-1 = 96.5 ± 2.29% versus
T0 = 98.2 ± 1.62%; p < 0.001) were observed, in addition
to a reduction of respiratory system resistance (T-1 = 14.2 ±
4.63cmH2O/L/s versus T0 = 11.0 ± 3.43cmH2O/L/s; p
< 0.001), after applying the respiratory physiotherapy protocol. All changes
were present in the assessment performed one hour (T+1) after the
application of the respiratory physiotherapy protocol. Regarding the hemodynamic
variables, an immediate increase in the heart rate after application of the
protocol was observed, but that increase was not maintained (T-1 = 88.9
± 18.7 bpm versus T0 = 93.7 ± 19.2bpm versus
T+1 = 88.5 ± 17.1bpm; p < 0.001). Conclusion Respiratory therapy leads to immediate changes in the lung mechanics and
hemodynamics of mechanical ventilation-dependent patients, and ventilatory changes
are likely to remain for at least one hour.

Abstract
Objective To assess the effects of manual hyperinflation, performed with a manual
resuscitator with and without the positive end-expiratory pressure valve, on
the respiratory function of preterm newborns under mechanical
ventilation. Methods Cross-sectional study of hemodynamically stable preterm newborns with
gestational age of less than 32 weeks, under mechanical ventilation and
dependent on it at 28 days of life. Manual hyperinflation was applied
randomly, alternating the use or not of the positive end-expiratory pressure
valve, followed by tracheal aspiration for ending the maneuver. For nominal
data, the two-tailed Wilcoxon test was applied at the 5% significance level
and 80% power. Results Twenty-eight preterm newborns, with an average birth weight of 1,005.71
± 372.16g, an average gestational age of 28.90 ± 1.79 weeks,
an average corrected age of 33.26 ± 1.78 weeks, and an average
mechanical ventilation time of 29.5 (15 - 53) days, were studied. Increases
in inspiratory and expiratory volumes occurred between time-points A5
(before the maneuver) and C1 (immediately after tracheal aspiration) in both
the maneuver with the valve (p = 0.001 and p = 0.009) and without the valve
(p = 0.026 and p = 0.001), respectively. There was also an increase in
expiratory resistance between time-points A5 and C1 (p = 0.044). Conclusion Lung volumes increased when performing the maneuver with and without the
valve, with a significant difference in the first minute after aspiration.
There was a significant difference in expiratory resistance between the
time-points A5 (before the maneuver) and C1 (immediately after tracheal
aspiration) in the first minute after aspiration within each maneuver.

Abstract
Context: As physiotherapy (PT) is a young profession in Nepal, there is a dearth of insight into the common practices of physiotherapists in critical care. Aims: To identify the availability of PT services in Intensive Care Units (ICUs) and articulate the common practices by physiotherapists in ICUs of Nepal. Settings and Design: All tertiary care hospitals across Nepal with ICU facility via an exploratory cross-sectional survey. Subjects and Methods: An existing questionnaire was distributed to all the physiotherapists currently working in ICUs of Nepal with 2 years of experience. The survey was sent via E-mail or given in person to 86 physiotherapists. Statistical Analysis Used: Descriptive and inferential statistics according to nature of data. Results: The response rate was 60% (n = 52). In the majority of hospitals (68%), PT service was provided only after a physician consultation, and few hospitals (13%) had established hospital criteria for PT in ICUs. Private hospitals (57.1%) were providing PT service in weekends compared to government hospitals (32.1%) (P = 0.17). The likelihood of routine PT involvement varied significantly with the clinical scenarios (highest 71.2% status cerebrovascular accident, lowest 3.8% myocardial infarction, P < 0.001). The most preferred PT treatment was chest PT (53.8%) and positioning (21.2%) while least preferred was therapeutic exercise (3.8%) irrespective of clinical scenarios. Conclusions: There is a lack of regular PT service during weekends in ICUs of Nepal. Most of the cases are treated by physiotherapists only after physician's referral. The preferred intervention seems to be limited only to chest PT and physiotherapists are not practicing therapeutic exercise and functional mobility training to a great extent.

Abstract
Despite widespread practice, there is very little, high-level evidence supporting the indications for and effectiveness of cardiopulmonary/chest physiotherapy (CPT) in critically ill infants and children. Conversely, most studies highlight the detrimental effects or lack of effect of different manual modalities. Conventional CPT should not be a routine intervention in the pediatric intensive care unit, but can be considered when obstructive secretions are present which impact on lung mechanics and/or gaseous exchange and/or where there is the potential for long-term complications. Techniques such as positioning, early mobilization, and rehabilitation have been shown to be beneficial in adult intensive care patients; however, little attention has been paid to this important area of practice in pediatric intensive care units. This article presents a narrative review of chest physiotherapy in pediatric critical illness, including effects, indications, precautions, and specific treatment modalities and techniques.

Differential Effects of Endotracheal Suctioning on Gas Exchanges in Patients with Acute Respiratory Failure under Pressure-Controlled and Volume-Controlled Ventilation. BIOMED RESEARCH INTERNATIONAL 2015; 2015:941081. [PMID: 25954759 PMCID: PMC4411449 DOI: 10.1155/2015/941081] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2014] [Revised: 02/05/2015] [Accepted: 03/23/2015] [Indexed: 01/13/2023]
Abstract
This study was conducted to evaluate the effects of open endotracheal suctioning on gas exchange and respiratory mechanics in ARF patients under the modes of PCV or VCV. Ninety-six ARF patients were treated with open endotracheal suctioning and their variations in respiratory mechanics and gas exchange after the suctions were compared. Under PCV mode, compared with the initial level of tidal volume (VT), ARF patients showed 30.0% and 27.8% decrease at 1 min and 10 min, respectively. Furthermore, the initial respiratory system compliance (Crs) decreased by 29.6% and 28.5% at 1 min and 10 min, respectively. Under VCV mode, compared with the initial level, 38.6% and 37.5% increase in peak airway pressure (PAP) were found at 1 min and 10 min, respectively. Under PCV mode, the initial PaO2 increased by 6.4% and 10.2 % at 3 min and 10 min, respectively, while 18.9% and 30.6% increase of the initial PaO2 were observed under VCV mode. Summarily, endotracheal suctioning may impair gas exchange and decrease lung compliance in ARF patients receiving mechanical ventilation under both PCV and VCV modes, but endotracheal suctioning effects on gas exchange were more severe and longer-lasting under PCV mode than VCV.

Clinical effects of specialist and on-call respiratory physiotherapy treatments in mechanically ventilated children: A randomised crossover trial. Physiotherapy 2015; 101:349-56. [PMID: 25749495 DOI: 10.1016/j.physio.2014.12.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2014] [Accepted: 12/27/2014] [Indexed: 11/24/2022]
Abstract
OBJECTIVES The study investigated treatment outcomes when respiratory physiotherapy was delivered by non-respiratory on-call physiotherapists, compared with specialist respiratory physiotherapists. DESIGN Prospective, randomised crossover trial. SETTING Paediatric, tertiary care hospital in the United Kingdom. PARTICIPANTS Mechanically ventilated children requiring two physiotherapy interventions during a single day were eligible. Twenty two physiotherapists (10 non-respiratory) and 93 patients were recruited. INTERVENTIONS Patients received one treatment from a non-respiratory physiotherapist and another from a respiratory physiotherapist, in a randomised order. Treatments were individualised to the patients' needs, often including re-positioning followed by manual lung inflations, chest wall vibrations and endotracheal suction. MAIN OUTCOME MEASURES The primary outcome was respiratory compliance. Secondary outcomes included adverse physiological events and clinically important respiratory changes (according to an a priori definition). RESULTS Treatments delivered to 63 patients were analysed. There were significant improvements to respiratory compliance (mean increase [95% confidence intervals], 0.07 and 0.08ml·cmH2O(-1)·kg(-1) [0.01 to 0.14 and 0.04 to 0.13], p<0.01, for on-call and respiratory physiotherapists' treatments respectively). Case-by-case, there were fewer clinically important improvements following non-respiratory physiotherapists' treatments compared with the respiratory physiotherapists' (n=27 [43%] versus n=40 [63%], p=0.03). Eleven adverse events occurred, eight following non-respiratory physiotherapists' treatments. CONCLUSIONS Significant disparities exist in treatment outcomes when patients are treated by non-respiratory on-call physiotherapists, compared with specialist respiratory physiotherapists. There is an urgent need for targeted training strategies, or alternative service delivery models, to be explored. This should aim to address the quality of respiratory physiotherapy services, both during and outside of normal working hours. CLINICAL TRIAL REGISTRATION NUMBER Clinicaltrials.gov, NCT01999426.

Abstract
OBJECTIVE To determine the efficacy of chest compression accompanied by a 10-cmH2O increase in baseline inspiratory pressure on pressure support ventilation, in comparison with that of aspiration alone, in removing secretions, normalizing hemodynamics, and improving respiratory mechanics in patients on mechanical ventilation. METHODS This was a randomized crossover clinical trial involving patients on mechanical ventilation for more than 48 h in the ICU of the Porto Alegre Hospital de Clínicas, in the city of Porto Alegre, Brazil. Patients were randomized to receive aspiration alone (control group) or compression accompanied by a 10-cmH2O increase in baseline inspiratory pressure on pressure support ventilation (intervention group). We measured hemodynamic parameters, respiratory mechanics parameters, and the amount of secretions collected. RESULTS We included 34 patients. The mean age was 64.2 ± 14.6 years. In comparison with the control group, the intervention group showed a higher median amount of secretions collected (1.9 g vs. 2.3 g; p = 0.004), a greater increase in mean expiratory tidal volume (16 ± 69 mL vs. 56 ± 69 mL; p = 0.018), and a greater increase in mean dynamic compliance (0.1 ± 4.9 cmH2O vs. 2.8 ± 4.5 cmH2O; p = 0.005). CONCLUSIONS In this sample, chest compression accompanied by an increase in pressure support significantly increased the amount of secretions removed, the expiratory tidal volume, and dynamic compliance.

Abstract
AIM To determine whether a literature-based guideline, powered by educational meetings and individual feedback, improves manual hyperinflation (MH) performance by intensive care unit (ICU) nurses. BACKGROUND MH is frequently applied in intubated and mechanically ventilated ICU patients. MH is a complex intervention, and large variation in its performance has been found. MATERIALS AND METHODS First, a literature-based guideline on MH was developed. The intervention consisted of education of this guideline and individual feedback. Before and 3 months after the intervention, ICU nurses performed MH maneuvers in a skills laboratory. Data collected included applied volumes, peak inspiratory flows (PIF) and peak expiratory flows (PEF), and the use of inspiratory holds. RESULTS Eighty nurses participated. Decrease of PIF was not statistically significant. PEF increased from 52 ± 7 to 83 ± 23 L/min (P < 0·01). PIF to PEF ratio decreased from 1·4 [1·1-1·7] to 0·8 [0·6-1·1] (P < 0·01). Peak inspiratory pressures decreased from 40 ± 14 to 19 ± 6 cm H2 O (P < 0·01). The proportion of nurses applying inspiratory holds increased from 14% to 58%; use of rapid release of the resuscitation bag, considered mandatory, increased from 4% to 61%. CONCLUSION Implementation of a literature-based guideline on MH, powered by educational meetings and individual feedback, improves MH performance by ICU nurses. RELEVANCE TO CLINICAL PRACTICE If it is decided to practice MH in the care of the intubated and mechanical ventilated patient, a standardized, uniform performed MH procedure is a prerequisite.

Manual hyperinflation combined with expiratory rib cage compression for reduction of length of ICU stay in critically ill patients on mechanical ventilation. J Bras Pneumol 2013; 38:477-86. [PMID: 22964932 DOI: 10.1590/s1806-37132012000400010] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2011] [Accepted: 05/10/2012] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE Although manual hyperinflation (MH) is widely used for pulmonary secretion clearance, there is no evidence to support its routine use in clinical practice. Our objective was to evaluate the effect that MH combined with expiratory rib cage compression (ERCC) has on the length of ICU stay and duration of mechanical ventilation (MV). METHODS This was a prospective randomized controlled clinical trial involving ICU patients on MV at a tertiary care teaching hospital between January of 2004 and January of 2005. Among the 49 patients who met the study criteria, 24 and 25 were randomly assigned to the respiratory physiotherapy (RP) and control groups, respectively. Of those same patients, 6 and 8, respectively, were later withdrawn from the study. During the 5-day observation period, the RP patients received MH combined with ERCC, whereas the control patients received standard nursing care. RESULTS The two groups were similar in terms of the baseline characteristics. The intervention had a positive effect on the duration of MV, as well as on the ICU discharge rate and Murray score. There were significant differences between the control and RP groups regarding the weaning success rate on days 2 (0.0% vs. 37.5%), 3 (0.0% vs. 37.5%), 4 (5.3% vs. 37.5%), and 5 (15.9% vs. 37.5%), as well as regarding the ICU discharge rate on days 3 (0% vs. 25%), 4 (0% vs. 31%), and 5 (0% vs. 31%). In the RP group, there was a significant improvement in the Murray score on day 5. CONCLUSIONS Our results show that the use of MH combined with ERCC for 5 days accelerated the weaning process and ICU discharge.

Abstract
INTRODUÇÃO: A Fisioterapia vem atuando com o objetivo de reduzir falhas no desmame da ventilação mecânica (VM) que podem repercutir em desfechos desfavoráveis para o paciente. OBJETIVO: Avaliar os efeitos da fisioterapia no desmame da VM. MATERIAIS E MÉTODOS: Estudo transversal e controlado com pacientes adultos. A formação dos grupos estudados foi resultado de dois períodos ocorridos em uma UTI; em determinado período, a unidade contou com a presença de um profissional de Fisioterapia, em outro, não teve a presença desse profissional por razões administrativas. Registraram-se os resultados do desmame por meio de coleta diária de informações. Foram estudados 50 pacientes, 31 fizeram fisioterapia (grupo fisioterapia, GF) e 19 não fizeram (grupo controle, GC). O GF realizou dois atendimentos diários (quarenta minutos cada), composto das técnicas: compressão do tórax, hiperinsuflação manual, aspiração traqueal e de vias aéreas, movimentação e condução do desmame. O GC recebeu tratamento médico usual. RESULTADOS: Observou-se no GF e GC, respectivamente: sucesso no desmame - 71% (22) e 21% (4) (p = 0,001); tempo de VM - 152 ± 142 e 414 ± 344 horas (p = 0,04); tempo de desmame: 13 ± 48 e 140 ± 122 horas (p < 0,0001); tempo de internação na UTI - 338 ± 192 e 781 ± 621 horas (p = 0,007); tempo de internação hospitalar - 710 ± 628 e 1108 ± 720 horas (p = 0,058); mortalidade: 35% (11) e 47% (9) (p = 0,41). CONCLUSÃO: A fisioterapia esteve associada ao aumento do sucesso no desmame, à redução do tempo de desmame, tempo de VM e de internação na UTI. Não houve diferença no tempo de internação hospitalar e na mortalidade.

Abstract
INTRODUÇÃO: A técnica de hiperinsuflação manual (HM), também conhecida como "bag squeezing" ou "bagging", foi inicialmente descrita como um recurso para melhorar a oxigenação pré e pós-aspiração traqueal, mobilizar o excesso de secreção brônquica e reexpandir áreas pulmonares colapsadas. OBJETIVO: Apresentar evidências científicas sobre os efeitos da manobra de HM como recurso fisioterapêutico, bem como suas indicações clínicas. MATERIAIS E MÉTODOS: Realizou-se uma busca nas bases de dados eletrônicas SciELO, ScienceDirect, PubMed e PEDro, utilizando-se os descritores "hiperinsuflação manual" (manual hyperinflation) e "fisioterapia" (physiotherapy). Como critério de inclusão considerou-se: conter os descritores no título ou resumo; ensaios clínicos que abordassem "hiperinsuflação manual" e fisioterapia; textos em inglês e português; publicações entre 1994 e 2011. RESULTADOS: Foram selecionados 25 estudos e todos apontaram a importância dessa manobra na mobilização de secreções traqueobrônquicas e para reexpansão de alvéolos colapsados, devido à melhora do volume pulmonar. Adequação das trocas gasosas, melhora da oxigenação e da complacência pulmonar, prevenção e tratamento de atelectasias são outras indicações. Também é consensual a preocupação com a padronização na aplicação da técnica. Melhores resultados são alcançados quando o volume aplicado é cerca de 50% maior que o volume corrente do paciente. Precauções quanto a limites de pressão em torno de 40 cm H2O, para se evitar barotraumas, também são referidas pela maioria dos estudos. CONCLUSÃO: A literatura traz evidências que sustentam a indicação do HM para mobilização e eliminação de secreções traqueobrônquicas e prevenção de infecções/complicações, além da necessidade de padronização da técnica.

Abstract
INTRODUÇÃO: Durante a ventilação mecânica (VM) as vias aéreas podem acumular secreção. Pacientes em VM são submetidos a Fisioterapia Respiratória (FR) e a aspiração traqueal, associados ou isoladamente, com objetivo de higienizar as vias aéreas. OBJETIVO: Comparar os efeitos da aplicação de diferentes protocolos de higiene brônquica na pressão arterial, frequência cardíaca, saturação de oxigênio e frequência respiratória de pacientes submetidos à VM. MATERIAIS E MÉTODOS: Realizou-se estudo prospectivo e aleatório, controlado do tipo cruzado, com amostra não probabilística intencional no Hospital das Clínicas da Faculdade de Medicina de Marília. Foram incluídos pacientes em VM invasiva que foram submetidos a três protocolos de higienização brônquica: PFR - protocolo de fisioterapia (compressão torácica manual e hiperinsuflação manual); PAT - protocolo de aspiração; e PFR + PAT. Frequência respiratória, pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), saturação periférica de oxigênio e frequência cardíaca foram avaliadas em três momentos: antes (M1), imediatamente após (M2), e 30 minutos após (M3) cada protocolo. As diferenças entre protocolos e momentos foram verificadas por meio do teste ANOVA e pos-hoc de Student Newman-Keus (p < 0,05). RESULTADOS: Foram avaliados 18 pacientes com 71,2 ± 13,9 anos de idade e com 15,1 ± 17,7 dias de VM. Não houve diferenças entre os protocolos. Diminuíram de forma significativa a PAS (p = 0,0261) e a PAD (p = 0,0119) de M2 para M3 no protocolo de aspiração. CONCLUSÃO: Pacientes em VM apresentaram diminuição da pressão arterial após 30 minutos de aspiração e não apresentaram alteração nas outras variáveis estudadas. Não houve diferença entre os protocolos.

Abstract
BACKGROUND Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia. OBJECTIVES To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults. SEARCH METHODS We searched CENTRAL 2012, Issue 11, MEDLINE (1966 to November week 2, 2012), EMBASE (1974 to November 2012), Physiotherapy Evidence Database (PEDro) (1929 to November 2012), CINAHL (2009 to November 2012) and CBM (1978 to November 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) assessing the efficacy of chest physiotherapy for treating pneumonia in adults. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial eligibility, extracted data and appraised trial quality. Primary outcomes were mortality and cure rate. We used risk ratios (RR) and mean difference (MD) for individual trial results in the data analysis. We performed meta-analysis and measured all outcomes with 95% confidence intervals (CI). MAIN RESULTS Six RCTs (434 participants) appraised four types of chest physiotherapy (conventional chest physiotherapy; osteopathic manipulative treatment (which includes paraspinal inhibition, rib raising and myofascial release); active cycle of breathing techniques (which include active breathing control, thoracic expansion exercises and forced expiration techniques); and positive expiratory pressure).None of the physiotherapies (versus no physiotherapy or placebo) improved mortality rates of adults with pneumonia.Conventional chest physiotherapy (versus no physiotherapy), active cycle of breathing techniques (versus no physiotherapy) and osteopathic manipulative treatment (versus placebo) did not increase the cure rate or chest X-ray improvement rate.Osteopathic manipulative treatment (versus placebo) and positive expiratory pressure (versus no physiotherapy) reduced the mean duration of hospital stay by 2.0 days (mean difference (MD) -2.0 days, 95% CI -3.5 to -0.6) and 1.4 days (MD -1.4 days, 95% CI -2.8 to -0.0), respectively. Conventional chest physiotherapy and active cycle of breathing techniques did not.Positive expiratory pressure (versus no physiotherapy) reduced fever duration (MD -0.7 day, 95% CI -1.4 to -0.0). Osteopathic manipulative treatment did not.Osteopathic manipulative treatment (versus placebo) reduced the duration of intravenous (MD -2.1 days, 95% CI -3.4 to -0.9) and total antibiotic treatment (MD -1.9 days, 95% CI -3.1 to -0.7).Limitations of this review are that the studies addressing osteopathic manipulative treatment were small, and that six published studies which appear to meet the inclusion criteria are awaiting classification. AUTHORS' CONCLUSIONS Based on current limited evidence, chest physiotherapy might not be recommended as routine additional treatment for pneumonia in adults.

Abstract
Introduction Manual hyperinflation (MH), a frequently applied maneuver in critically ill intubated and mechanically ventilated patients, is suggested to mimic a cough so that airway secretions are mobilized toward the larger airways, where they can easily be removed. As such, MH could prevent plugging of the airways. Methods We performed a search in the databases of Medline, Embase, and the Cochrane Library from January 1990 to April 2012. We systematically reviewed the literature on evidence for postulated benefits and risks of MH in critically ill intubated and mechanically ventilated patients. Results The search identified 50 articles, of which 19 were considered relevant. We included 13 interventional studies and six observational studies. The number of studies evaluating physiological effects of MH is limited. Trials differed too much to permit meta-analysis. It is uncertain whether MH was applied similarly in the retrieved studies. Finally, most studies are underpowered to show clinical benefit of MH. Use of MH is associated with short-term improvements in lung compliance, oxygenation, and secretion clearance, without changes in outcomes. MH has been reported to be associated with short-term and probably clinically insignificant side effects, including decreases in cardiac output, alterations of heart rates, and increased central venous pressures. Conclusions Studies have failed to show that MH benefits critically ill intubated and mechanically ventilated patients. MH is infrequently associated with short-term side effects.

Abstract
OBJECTIVES Manual hyperinflation (MHI) has been shown to improve lung compliance, reduce airway resistance, and enhance secretion removal and peak expiratory flow. The aims of this study were to investigate whether there is a difference in airflow distribution through patients' lungs when using the Laerdal and Mapleson-C circuits at a set level of positive end-expiratory pressure (PEEP), and to establish whether differences in lung compliance and haemodynamic status exist when patients are treated with both these MHI circuits. DESIGN Crossover randomised controlled trial. SETTING Adult multidisciplinary intensive care unit (ICU) at an academic hospital. PARTICIPANTS Fifteen adult patients were recruited and served as their own controls. INTERVENTION In the Nuclear Medicine Department, MHI with PEEP 7.5 cmH(2)O was performed in the supine position (Day 1) with either Laerdal or Mapleson-C circuits, in a random order, while technetium-99m (Tc-99m) aerosol was administered and images were taken with a gamma camera. Changes in heart rate (HR), mean arterial pressure (MAP) and dynamic lung compliance (C(D)) were documented at baseline, immediately after return to ICU, and 10, 20 and 30 minutes after return to ICU. The alternative circuit was used on Day 2. RESULTS Tc-99m deposition was greater in the right lung field (62% and 63% for Laerdal and Mapleson-C circuits, respectively) than the left lung field (38% and 37%, respectively) for all patients, and least deposition occurred in the left lower segments (6% and 6%, respectively). No differences in Tc-99m deposition in the lungs, HR, MAP or C(D) were noted between the two MHI circuits. CONCLUSION Airflow distribution through patients' lungs was similar when the Laerdal and Mapleson-C MHI circuits were compared using a set level of PEEP in the supine position.

Abstract
The aim of hyperinflation in the ventilated intensive care unit patient is to increase oxygenation, reverse lung collapse and clear sputum. The efficacy and consistency of manual hyperventilation is well supported in the literature, but there is limited published evidence supporting hyperventilation utilising a ventilator. Despite this, a recent survey established that almost 40% of Australian tertiary intensive care units utilise ventilator hyperinflation. The aim of this non-inferiority cross-over study was to determine whether ventilator hyperinflation was as effective as manual hyperinflation in clearing sputum from patients receiving mechanical ventilation using a prescriptive ventilator hyperinflation protocol. Forty-six patients received two randomly ordered physiotherapy treatments on the same day by the same physiotherapist. The efficacy of the hyperinflation modes was measured by sputum wet weight. Secondary measures included compliance, tidal volume, airway pressure and PaO2/FiO2 ratio. There was no difference in wet weight of sputum cleared using ventilator hyperinflation or manual hyperinflation (mean 3.2 g, P=0.989). Further, no difference in compliance (P=0.823), tidal volume (P=0.219), heart rate (P=0.579), respiratory rate (P=0.929) or mean arterial pressure (P=0.593) was detected. A statistically significant difference was seen in mean airway pressure (P=0.002) between techniques. The effect of techniques on the PaO2/FiO2 response ratio was dependent on time (interaction P=0.024). Physiotherapy using ventilator hyperinflation cleared a comparable amount of sputum and was as safe as manual hyperinflation. This research describes a ventilator hyperinflation protocol that will serve as a platform for continued discussion, research and development of its application in ventilated patients.

Abstract
Background: Despite remarkable progress that has been achieved in the recent years in the diagnosis, prevention, and therapy for ventilator-associated pneumonia (VAP), this disease continues to create complication during the course of treatment in a significant proportion of patients while receiving mechanical ventilation. Objective: This study was designed to evaluate the effect of multimodality chest physiotherapy in intubated and mechanically ventilated patients undergoing treatment in the intensive care units (ICUs) for prevention of VAP. Patients and Methods: A total of 101 adult intubated and mechanically ventilated patients were included in this study. Manual hyperinflation (MH) and suctioning were administered to patients in the control group (n = 51), and positioning and chest wall vibrations in addition to MH plus suctioning (multimodality chest physiotherapy) were administered to patients in the study group (n = 50) till they were extubated. Both the groups were subjected to treatment twice a day. Standard care in the form of routine nursing care, pharmacological therapy, inhalation therapy, as advised by the concerned physician/surgeon was strictly implemented throughout the intervention period. Results: Data were analyzed using SPSS window version 9.0. The Clinical Pulmonary infection Score (CPIS) Score showed significant decrease at the end of extubation/successful outcome or discharge in both the groups (P = 0.00). In addition, significant decrease in mortality rate was noted in the study group (24%) as compared to the control group (49%) (P = 0.007). Conclusions: It was observed in this study that twice-daily multimodality chest physiotherapy was associated with a significant decrease in the CPIS Scores in the study group as compared to the control group suggesting a decrease in the occurrence of VAP. There was also a significant reduction in the mortality rates with the use of multimodality chest physiotherapy in mechanically ventilated patients.

Abstract
QUESTIONS What is the effect of increasing pressure support during the application of manual chest wall compression with vibrations for secretion clearance in intubated patients in intensive care? DESIGN A randomised trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS 66 patients receiving mechanical ventilation for greater than 48 hours. INTERVENTION All participants were positioned supine in bed with the backrest elevated 30 degrees. The experimental group received manual chest wall compression with vibrations during which their pressure support ventilation was increased by 10 cm H(2)O over its existing level. The control group received manual chest wall compression with vibrations but no adjustment of the ventilator settings. Both groups then received airway suction. OUTCOME MEASURES The primary outcome was the weight of the aspirate. Secondary outcomes were pulmonary and haemodynamic measures and oxygenation. RESULTS Although both treatments increased the weight of the aspirate compared to baseline, the addition of increased pressure support during manual chest wall compression with vibrations did not significantly increase the clearance of secretions, mean between-group difference in weight of the aspirate 0.4 g, 95% CI -0.5 to 1.4. Although several other measures also improved in one or both groups with treatment, there were no significant differences between the groups for any of the secondary outcomes. CONCLUSION Although increasing pressure support has previously been shown to increase secretion clearance in intubated patients, the current study did not show any benefits when it was added to chest wall compression with vibrations. TRIAL REGISTRATION NCT01155648.

Abstract
A fisioterapia respiratória tem papel fundamental nos casos de complicações pelo excesso de secreção broncopulmonar. Manobras de remoção de secreção brônquica como a vibrocompressão e o aumento do fluxo expiratório (AFE) garantem a perviabilidade das vias aéreas. O objetivo deste trabalho foi avaliar o efeito das manobras de AFE e vibrocompressão para remoção de secreção e suas repercussões hemodinâmicas e ventilatórias em pacientes traqueostomizados. Participaram 20 pacientes (com 18 a 73 anos) de ambos os sexos com diagnóstico fisioterapêutico de hipersecreção e/ou retenção de muco brônquico, submetidos à aplicação dessas técnicas e à remoção de secreção, que foram avaliados antes e depois da intervenção quanto a parâmetros hemodinâmicos e respiratórios. Com a aplicação da técnica de vibrocompressão foi verificada queda significativa (p<0,05) nas pressões arteriais (PA) diastólica e média de 82,2±13,4 para 77,4±13,3 mmHg e de 104,3±18,2 para 90,9±9,07 mmHg, respectivamente; o mesmo ocorreu com a PA média (p<0,05) após a aplicação da técnica de AFE, de 103,5±13,2 para 94,1±9,0 mmHg. Não houve diferença entre as técnicas aplicadas quanto ao volume de secreção removida (p=0,60). Pacientes traqueostomizados apresentaram pois redução da pressão arterial após 30 minutos da aplicação das técnicas fisioterapêuticas, mas não houve diferença entre as técnicas utilizadas quanto ao volume de secreção removida.

Abstract
BACKGROUND Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia. OBJECTIVES To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, issue 3); MEDLINE (1966 to August 2009); EMBASE (1974 to August 2009); CBM (1978 to August 2009); the National Research Register (August 2009) and Physiotherapy Evidence Database (PEDro) (1929 to August 2009). SELECTION CRITERIA Randomised controlled trials (RCTs) assessing the efficacy of chest physiotherapy for treating pneumonia in adults. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial eligibility, extracted data and appraised trial quality. Primary outcomes were mortality and cure rate. We used risk ratios (RR) and mean difference (MD) for individual trial results in the data analysis. We performed meta-analysis and measured all outcomes with 95% confidence intervals (CI). MAIN RESULTS Six RCTs (434 participants) appraised four types of chest physiotherapy (conventional chest physiotherapy; osteopathic manipulative treatment (which includes paraspinal inhibition, rib raising and myofascial release); active cycle of breathing techniques (which include active breathing control, thoracic expansion exercises and forced expiration techniques); and positive expiratory pressure).None of the physiotherapies (versus no physiotherapy or placebo) improved mortality rates of adults with pneumonia.Conventional chest physiotherapy (versus no physiotherapy), active cycle of breathing techniques (versus no physiotherapy) and osteopathic manipulative treatment (versus placebo) did not increase the cure rate or chest X-ray improvement rate.Osteopathic manipulative treatment (versus placebo) and positive expiratory pressure (versus no physiotherapy) reduced mean duration of hospital stay by 2.0 days (mean difference (MD) -2.0 days, 95% CI -3.5 to -0.6) and 1.4 days (MD -1.4 days, 95% CI -2.8 to -0.0), respectively. Conventional chest physiotherapy and active cycle of breathing techniques did not.Positive expiratory pressure (versus no physiotherapy) reduced fever duration (MD -0.7 day, 95% CI -1.4 to -0.0). Osteopathic manipulative treatment did not.Osteopathic manipulative treatment (versus placebo) reduced duration of intravenous (MD -2.1 days, 95% CI -3.4 to -0.9) and total antibiotic treatment (MD -1.9 days, 95% CI -3.1 to -0.7).Limitations of this review are that the studies addressing osteopathic manipulative treatment were small, and that the six published studies which appear to meet the inclusion criteria are awaiting classification. AUTHORS' CONCLUSIONS Based on current limited evidence, chest physiotherapy might not be recommended as routine adjunctive treatment for pneumonia in adults.

Abstract
BACKGROUND Manual hyperinflation is a treatment technique commonly used by physiotherapists in intensive care units to reverse or prevent atelectasis and mobilize airway secretions in intubated patients. The aim of this study was to determine which of the Magill (Rusch Manufacturing Ltd, Craigavon, UK) or Mapleson-C (CIG DF 655, CIG Medishield, Sydney, Australia) manual hyperinflation circuits was theoretically more effective at mobilizing secretions. METHODS A semi-blinded crossover study of 12 physiotherapists with tertiary level intensive care unit experience was conducted on a benchtop model. The order of circuits and compliance settings was randomized. RESULTS The Mapleson-C circuit produced a significantly faster peak expiratory flow (F[1, 210]=14.51, P < or = .01) and smaller inspiratory to expiratory flow ratio (F[1, 210]=28.44, P < or = .01) than the Magill circuit regardless of compliance settings. CONCLUSION The results of this study suggest that the Mapleson-C manual hyperinflation circuit may be more effective at mobilizing secretions.

Abstract
OBJECTIVES To update a previous clinical practice guideline on suctioning in adult patients, published in the Canadian Respiratory Journal in 2001. METHODS A primary search of the MEDLINE (from 1998), CINAHL, EMBASE and The Cochrane Library (all from 1996) databases up to November 2007, was conducted. These dates reflect the search limits reached in the previous clinical practice guideline. A secondary search of the reference lists of retrieved articles was also performed. Two reviewers independently appraised each study before meeting to reach consensus. Study quality was evaluated using the Jadad and PEDro scales. When sufficient data were available, a meta-analysis was conducted using a random effects model. Data are reported as ORs, weighted mean differences and 95% CIs. When no comparisons were possible, qualitative analyses of the data were completed. RESULTS Eighty-one studies were critically appraised from a pool of 123. A total of 28 randomized controlled trials or randomized crossover studies were accepted for inclusion. Meta-analysis was possible for open versus closed suctioning only. Recommendations from 2001 with respect to hyperoxygenation, hyperinflation, use of a ventilator circuit adaptor and subglottic suctioning were confirmed. New evidence was identified with respect to indications for suctioning, open suction versus closed suction systems, use of medications and infection control. CONCLUSIONS While new evidence continues to be varied in strength, and is still lacking in some areas of suctioning practice, the evidence base has improved since 2001. Members of the health care team should incorporate this evidence into their practice.

Abstract
OBJECTIVE To provide a comprehensive, evidence-based review of pediatric endotracheal suctioning: effects, indications, and clinical practice. METHODS PubMed, Cumulative Index of Nursing and Allied Health Literature, and PEDro (Physiotherapy Evidence Database) electronic databases were searched for English language articles, published between 1962 and June 2007. Owing to the paucity of objective pediatric data, all reports dealing with this topic were examined, including adult and neonatal studies. RESULTS One hundred eighteen references were included in the final review. Despite the widespread use of endotracheal suctioning, very little high-level evidence dealing with pediatric endotracheal suctioning exists. Studies of mechanically ventilated neonatal, pediatric, and adult patients have shown that suctioning causes a range of potentially serious complications. Current practice guidelines are not based on evidence from controlled clinical trials. There is no clear evidence that endotracheal suctioning improves respiratory mechanics, with most studies pointing to the detrimental effect it has on lung mechanics. Suctioning should be performed when obstructive secretions are present rather than routinely. There is no clear evidence for the superiority of closed- or open-system suctioning, nor is there clear evidence for appropriate vacuum pressures and suction catheter size. Sterility does not seem to be necessary when suctioning. Preoxygenation has short-term benefits, but the longer-term impact is unknown. Routine saline instillation before suctioning should not be performed. Recruitment maneuvers performed after suctioning have not been shown to be useful as standard practice. CONCLUSIONS Endotracheal suctioning is a procedure used regularly in the pediatric intensive care unit. Despite this, good evidence supporting its practice is limited. Further, controlled clinical studies are needed to develop evidence-based protocols for endotracheal suctioning of infants and children, and to examine the impact of different suctioning techniques on the duration of ventilatory support, incidence of nosocomial infection, and length of pediatric intensive care unit and hospital stay.

Abstract
Maintenance of airway secretion clearance, or airway hygiene, is important for the preservation of airway patency and the prevention of respiratory tract infection. Impaired airway clearance often prompts admission to the intensive care unit (ICU) and can be a cause and/or contributor to acute respiratory failure. Physical methods to augment airway clearance are often used in the ICU but few are substantiated by clinical data. This review focuses on the impact of oral hygiene, tracheal suctioning, bronchoscopy, mucus-controlling agents, and kinetic therapy on the incidence of hospital-acquired respiratory infections, length of stay in the hospital and the ICU, and mortality in critically ill patients. Available data are distilled into recommendations for the maintenance of airway hygiene in ICU patients.

Abstract
QUESTION Does a recruitment manoeuvre after suctioning have any immediate or short-term effect on ventilation and gas exchange in mechanically-ventilated paediatric patients? DESIGN Randomised controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Forty-eight paediatric patients with heterogeneous lung pathology. Fourteen patients were subsequently excluded from analysis due to large leaks around the endotracheal tube. INTERVENTION The experimental group received a single standardised suctioning procedure followed five minutes later by a standardised recruitment manoeuvre. The control group received only the single suctioning procedure. OUTCOME MEASURES Measurements of ventilation (dynamic lung compliance, expiratory airway resistance, mechanical and spontaneous expired tidal volume, respiratory rate) and gas exchange (transcutaneous oxygen saturation) were recorded, on three occasions before and on two occasions after the recruitment manoeuvre, using a respiratory profile monitor. RESULTS There was no difference between the experimental and the control group in dynamic compliance, expired airway resistance, or oxygen saturation either immediately after the recruitment manoeuvre, or after 25 minutes. The experimental group decreased mechanical expired tidal volume by 0.3 ml/kg (95% CI 0.1 to 0.6), increased spontaneous expired tidal volume by 0.3 ml/kg (95% CI 0.0 to 0.6), and increased total respiratory rate by 3 bpm (95% CI 1 to 4) immediately after the recruitment manoeuvre compared with the control group, but these differences disappeared after 25 minutes. CONCLUSION There is insufficient evidence to support performing recruitment manoeuvres after suctioning infants and children.
