Abstract
PURPOSE Oxygen uptake (V˙o2) recovery kinetics appears to have considerable value in the assessment of functional capacity in both heart failure (HF) and chronic obstructive pulmonary disease (COPD). Noninvasive positive pressure ventilation (NIPPV) may benefit cardiopulmonary interactions during exercise. However, assessment during the exercise recovery phase is unclear. The purpose of this investigation was to explore the effects of NIPPV on V˙o2, heart rate, and cardiac output recovery kinetics from high-intensity constant-load exercise (CLE) in patients with coexisting HF and COPD. METHODS Nineteen males (10 HF/9 age- and left ventricular ejection fraction-matched HF-COPD) underwent 2 high-intensity CLE tests at 80% of peak work rate to the limit of tolerance (Tlim), receiving either sham ventilation or NIPPV. RESULTS Despite greater V˙o2 recovery kinetics on sham, HF-COPD patients presented with a faster exponential time constant τ (76.4 ± 14.0 sec vs 62.8 ± 15.2 sec, P < .05) and mean response time (MRT) (86.1 ± 19.1 sec vs 68.8 ± 12.0 sec, P < .05) with NIPPV and greater ΔNIPPV-sham (τ: 5.6 ± 19.5 vs -25.2 ± 22.4, P < .05; MRT: 4.1 ± 32.2 vs -26.0 ± 19.2, P < .05) compared with HF. There was no difference regarding Tlim between sham and NIPPV in both groups (P < .05). CONCLUSION Our results suggest that NIPPV accelerated the V˙o2 recovery kinetics following high-intensity CLE to a greater extent in patients with coexisting HF and COPD compared with HF alone. NIPPV should be considered when the objective is to apply high-intensity interval exercise training as an adjunct intervention during a cardiopulmonary rehabilitation program.

Abstract
Background The usefulness of non-invasive mechanical ventilation (NIMV) in oncohematological patients is still a matter of debate. Aim To analyze the rate of noninvasive ventilation failure and the main characteristics associated with this endpoint in oncohematological patients with acute respiratory failure (ARF). Methods A ventilatory support protocol was developed and implemented before the onset of the study. According to the PaO2/FiO2 (P/F) ratio and clinical judgment, patients received supplementary oxygen therapy, NIMV, or invasive mechanical ventilation (IMV). Results Eighty-two patients were included, average age between 52.1 ± 16 years old; 44 (53.6%) were male. The tested protocol was followed in 95.1% of cases. Six patients (7.3%) received IMV, 59 (89.7%) received NIMV, and 17 (20.7%) received oxygen therapy. ICU mortality rates were significantly higher in the IMV (83.3%) than in the NIMV (49.2%) and oxygen therapy (5.9%) groups (P < 0.001). Among the 59 patients who initially received NIMV, 30 (50.8%) had to eventually be intubated. Higher SOFA score at baseline (1.35 [95% CI = 1.12-2.10], P = 0.007), higher respiratory rate (RR) (1.10 [95% CI = 1.00-1.22], P = 0.048), and sepsis on admission (16.9 [95% CI = 1.93-149.26], P = 0.011) were independently associated with the need of orotracheal intubation among patients initially treated with NIMV. Moreover, NIMV failure was independently associated with ICU (P < 0.001) and hospital mortality (P = 0.049), and mortality between 6 months and 1 year (P < 0.001). Conclusion The implementation of a NIMV protocol is feasible in patients with hematological neoplasia admitted to the ICU, even though its benefits still remain to be demonstrated. NIMV failure was associated with higher SOFA and RR and more frequent sepsis, and it was also related to poor prognosis.

Hemodynamic effects of portable non-invasive ventilation in healthy men. Respir Physiol Neurobiol 2019; 268:103248.

Abstract
VitaBreath is a portable, non-invasive ventilation device (pNIV) that relieves shortness of breath in COPD by delivering fixed inspiratory and expiratory positive airway pressures (IPAP/EPAP: 18/8 cmH2O). Fixed pressures may cause circulatory compromise. We investigated the circulatory effects of pNIV during normal breathing (NB) and after Eucapnic Voluntary Hyperpnoea trials (EVH) sustained at 80% MVV. In a balanced order sequence, 10 healthy men performed four trials on one visit: 1-min of pNIV (intervention) or 1-min quiet breathing (QB) during NB; and 1-min pNIV (intervention) or 1-min QB during recovery from 3-min EVH. Compared to QB, pNIV application was associated with greater cardiac output (CO: 1.6 ± 1.9 L.min-1; P = 0.03). One minute into recovery from EVH, pNIV caused greater CO (2.2 ± 1.6 L.min-1; P = 0.01) compared to QB. Mean blood pressure was not different with pNIV compared to control. pNIV increased thoracoabdominal volumes and breathing frequency during NB and recovery from EVH. pNIV application does not induce adverse hemodynamic effects in healthy men.

Abstract
Mobilization of critically ill patients admitted to intensive care units should
be performed based on safety criteria. The aim of the present review was to
establish which safety criteria are most often used to start early mobilization
for patients under mechanical ventilation admitted to intensive care units.
Articles were searched in the PubMed, PEDro, LILACS, Cochrane and CINAHL
databases; randomized and quasi-randomized clinical trials, cohort studies,
comparative studies with or without simultaneous controls, case series with 10
or more consecutive cases and descriptive studies were included. The same was
performed regarding prospective, retrospective or cross-sectional studies where
safety criteria to start early mobilization should be described in the Methods
section. Two reviewers independently selected potentially eligible studies
according to the established inclusion criteria, extracted data and assessed the
studies' methodological quality. Narrative description was employed in data
analysis to summarize the characteristics and results of the included studies;
safety criteria were categorized as follows: cardiovascular, respiratory,
neurological, orthopedic and other. A total of 37 articles were considered
eligible. Cardiovascular safety criteria exhibited the largest number of
variables. However, respiratory safety criteria exhibited higher concordance
among studies. There was greater divergence among the authors regarding
neurological criteria. There is a need to reinforce the recognition of the
safety criteria used to start early mobilization for critically ill patients;
the parameters and variables found might contribute to inclusion into service
routines so as to start, make progress and guide clinical practice.

Abstract
OBJECTIVE During cardiac surgery, several factors contribute to the development of postoperative pulmonary complications. Non-invasive ventilation is a promising therapeutic tool for improving the functionality of this type of patient. The aim of this study is to evaluate the functional capacity and length of stay of patients in a nosocomial intensive care unit who underwent prophylactic non-invasive ventilation after heart valve replacement. METHOD The study was a controlled clinical trial, comprising 50 individuals of both sexes who were allocated by randomization into two groups with 25 patients in each group: the control group and experimental group. After surgery, the patients were transferred to the intensive care unit and then participated in standard physical therapy, which was provided to the experimental group after 3 applications of non-invasive ventilation within the first 26 hours after extubation. For non-invasive ventilation, the positive pressure was 10 cm H2O, with a duration of 1 hour. The evaluation was performed on the 7th postoperative day/discharge and included a 6-minute walk test. The intensive care unit and hospitalization times were monitored in both groups. Brazilian Registry of Clinical Trials (REBeC): RBR number 8bxdd3. RESULTS Analysis of the 6-minute walk test showed that the control group walked an average distance of 264.34±76 meters and the experimental group walked an average distance of 334.07±71 meters (p=0.002). The intensive care unit and hospitalization times did not differ between the groups. CONCLUSION Non-invasive ventilation as a therapeutic resource was effective toward improving functionality; however, non-invasive ventilation did not influence the intensive care unit or hospitalization times of the studied cardiac patients.

Abstract
Objective: To test the hypothesis that combined aerobic and resistance training and non-invasive ventilatory support result in additional benefits compared with combined aerobic and resistance training alone in heart failure patients. Design: A randomized, single-blind, controlled study. Setting: Cardiac rehabilitation center. Participants: A total of 46 patients with New York Heart Association class II/III heart failure were randomly assigned to a 10-week program of combined aerobic and resistance training, plus non-invasive ventilatory support ( n = 23) or combined aerobic and resistance training alone ( n = 23). Methods: Before and after intervention, results for the following were obtained: 6-minute walk test, forced vital capacity, forced expiratory volume at one second, maximal inspiratory muscle pressure, and maximal expiratory muscle pressure, with evaluation of dyspnea by the London Chest Activity of Daily Living scale, and quality of life with the Minnesota Living With Heart Failure questionnaire. Results: Of the 46 included patients, 40 completed the protocol. The combined aerobic and resistance training plus non-invasive ventilatory support, as compared with combined aerobic and resistance training alone, resulted in significantly greater benefit for dyspnea (mean change: 4.8 vs. 1.3, p = 0.004), and quality of life (mean change: 19.3 vs. 6.8, p = 0.017 ). In both groups, the 6-minute walk test improved significantly (mean change: 45.7 vs. 44.1, p = 0.924), but without a statistically significant difference. Conclusion: Non-invasive ventilatory support combined with combined aerobic and resistance training provides additional benefits for dyspnea and quality of life in moderate heart failure patients. Trial registration: ClinicalTrials.gov identifier: NCT02384798. Registered 03 April 2015.

Abstract
Recently, there has been increasing interest in the use of non invasive ventilation (NIV) to increase exercise capacity. In individuals with COPD, NIV during exercise reduces dyspnoea and increases exercise tolerance. Different modalities of mechanical ventilation have been used non-invasively as a tool to increase exercise tolerance in COPD, heart failure and lung and thoracic restrictive diseases. Inspiratory support provides symptomatic benefit by unloading the ventilatory muscles, whereas Continuous Positive Airway Pressure (CPAP) counterbalances the intrinsic positive end-expiratory pressure in COPD patients. Severe stable COPD patients undergoing home nocturnal NIV and daytime exercise training showed some benefits. Furthermore, it has been reported that in chronic hypercapnic COPD under long-term ventilatory support, NIV can also be administered during walking. Despite these results, the role of NIV as a routine component of pulmonary rehabilitation is still to be defined.
