Abstract
OBJECTIVES Current resuscitation guidelines recommend target chest compression depth (CCd) of approximately 4cm for infants and 5cm for children. Previous reports based on chest CT suggest these recommended CCd targets might be too deep for younger children. Our aim was to examine measurements of anterior-posterior chest diameter (APd) with a laser distance meter and calculate CCd targets in critically ill infants and children. DESIGN A retrospective descriptive study. SETTING Single-center PICU, using data from May 2019 to May 2022. PATIENTS All critically ill children admitted to PICU and under 8 years old were eligible to be included in the retrospective cohort. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The chest APd measurements using a laser distance meter are part of our usual practice on the PICU. Target CCd and the over-compression threshold CCd for each age group was calculated as 1/3 and 1/2 of APd, respectively. In 555 patients, the median (interquartile range) of the calculated target CCd for each age group was: 2.7 cm (2.5-2.9 cm), 2.9 cm (2.7-3.2 cm), 3.2 cm (3-3.5 cm), 3.4 cm (3.2-3.6 cm), 3.4 cm (3.2-3.6 cm), 3.6 cm (3.4-3.8 cm), 3.6 cm (3.4-4 cm), and 4 cm (3.5-4.2 cm), for 0, 2, 3-5, 6-8, 9-11, 12-17, 18-23, 24 to less than 60, and 60 to less than 96 months, respectively. Using guideline-recommended absolute CCd targets, 4 cm for infants and 5 cm for children, 49% of infants between 0 and 2 months, and 45.5% of children between 12 and 17 months would be over-compressed during cardiopulmonary resuscitation. CONCLUSIONS In our cohort, the 1/3 CCd targets calculated from APd measured by laser meter were shallower than the guideline-recommended CCd. Further studies including evaluating hemodynamics during cardiopulmonary resuscitation with these shallower CCd targets are needed.

Abstract
Background The study of thoracic injuries and biomechanics during CPR requires detailed studies that are very scarce. The role of the heart in CPR biomechanics has not been determined. This study aimed to determine the risk factors importance for serious ribcage damage due to CPR. Methods Data were collected from a prospective registry of out-of-hospital cardiac arrest between April 2014 and April 2017. This study included consecutive out-of-hospital CPR attempts undergoing an autopsy study focused on CPR injuries. Cardiac mass ratio was defined as the ratio of real to expected heart mass. Pearson's correlation coefficient was used to select clinically relevant variables and subsequently classification tree models were built. The Gini index was used to determine the importance of the associated serious ribcage damage factors. The LUCAS® chest compressions device forces and the cardiac mass were analyzed by linear regression. Results Two hundred CPR attempts were included (133 manual CPR and 67 mechanical CPR). The mean age of the sample was 60.4 ± 13.5, and 56 (28%) were women. In all, 65.0% of the patients presented serious ribcage damage. From the classification tree build with the clinically relevant variables, age (0.44), cardiac mass ratio (0.26), CPR time (0.22), and mechanical CPR (0.07), in that order, were the most influential factors on serious ribcage damage. The chest compression forces were greater in subjects with higher cardiac mass. Conclusions The heart plays a key role in CPR biomechanics being cardiac mass ratio the second most important risk factor for CPR injuries.

Abstract
PURPOSE This study aims to ascertain the prevalence of rib fractures and other injuries resulting from CPR and to compare manual with mechanically assisted CPR. An additional aim was to summarize the literature on surgical treatment for rib fractures following CPR. DESIGN Systematic review and meta-analysis. DATA SOURCES Embase, Medline Ovid, Cochrane Central, Web of Science, and Google Scholar. REVIEW METHODS The databases were searched to identify studies reporting on CPR-related injuries in patients who underwent chest compressions for a non-traumatic cardiopulmonary arrest. Subgroup analysis was conducted to compare the prevalence of CPR-related injuries in manual versus mechanically assisted chest compressions. Studies reporting on surgery for CPR-related rib fractures were also reviewed and summarized. RESULTS Seventy-four studies reporting CPR-related injuries were included encompassing a total of 16,629 patients. Any CPR-related injury was documented in 60% (95% confidence interval [95% CI] 49-71) patients. Rib fractures emerged as the most common injury, with a pooled prevalence of 55% (95% CI 48-62). Mechanically assisted CPR, when compared to manual CPR, was associated with a higher risk ratio for CPR-related injuries of 1.36 (95% CI 1.17-1.59). Eight studies provided information on surgical stabilization of CPR-related rib fractures. The primary indication for surgery was the inability to wean from mechanical ventilation in the presence of multiple rib fractures. CONCLUSION Rib fractures and other injuries frequently occur in patients who undergo CPR after a non-traumatic cardiopulmonary arrest, especially when mechanical CPR is administered. Surgical stabilization of CPR-related rib fractures remains relatively uncommon. LEVEL OF EVIDENCE Level III, systematic review and meta-analysis.

Abstract
Introduction Chest compressions during advanced cardiac life support is a life-saving, potential harmful procedure with high incidence of severe and life-threatening injuries. Previous studies suggest a possible correlation between the increased incidence of chest and/or abdominal trauma and the use of automatic mechanical compression devices. Methods An observational monocentric retrospective cohort study was conducted including all patients admitted to our Intensive Care Unit suffering from out-of-hospital cardiac arrest (OHCA) in Canton Ticino (Switzerland) from 2012 to 2021. The primary endpoint was to describe any resuscitation-related body injury. The secondary endpoints were to explore possible predictors of cardiopulmonary resuscitation (CPR) related injuries and their association with the 30-day mortality. Results We included 335 patients, 287 treated with manual chest compressions, 48 mechanically assisted. 55.5% of all resuscitated patients presented severe, or life-threatening lesions. Skeletal and thoracic injuries were the most frequent lesions followed by abdominal injuries. Mechanical assisted resuscitated patients presented higher risk of bleeding (OR 5.9; 95% CI 2.9-11.6) and increased CPR-related injuries (aOR 6.2; 95% CI 2.5-15.4) compared to standard manual chest compressions. In particular higher number of extra-thoracic and life-threatening lesions were described among the mechanical assisted CPR group. Patients with life-threatening had statistically significant higher mortality at 30-days compared to the severe and lesion's free cohort. Conclusion Traumatic lesions occurred frequently after chest compression and their severity was associated with increased 30-day mortality. Mechanical devices, compared to manual chest compression, appear to be more harmful and may play a role in causing body lesions and hemorrhagic events.

Abstract
BACKGROUND Autoresuscitation is the phenomenon of spontaneous return of circulation after cessation of CPR, also known as the Lazarus phenomenon. Most of the evidence is based on case reports and a few systematic reviews. The occurrence of autoresuscitation may lead to self-reproach and dismay in affected emergency personnel and may rise questions about the correct procedure after terminating resuscitative efforts. In contrast to existing cardiac arrest guidelines there is no standardized approach to terminating resuscitative attempts. CASE We report a case of out of hospital autoresuscitation in a 67-year-old female after 60 min of advanced cardiac life support. After shock refractory shockable rhythm, we recorded pulseless electrical activity and fixed pupils, consequently resuscitation was terminated. About 50 min later the patient surprisingly showed signs of life. Due to the suggestive history a coronary angiography was performed, showing severe coronary heart disease which necessitated surgical intervention. After ACBP surgery and intensive care followed by treatment on the cardiological ward, she was finally discharged to neurological rehabilitation. CONCLUSION As already proposed by existing literature, there should be at least a 10-min interval of close monitoring after abandoning CPR. Transport of a deceased patient should only take place after secure signs of death can be detected. Further investigation is needed to determine which patients are most likely to benefit from an extended observation period. Our case reports highlights the difficulties in death declaration and the importance of close monitoring after abandoning CPR.

Abstract
Donor vessel injury is a well-known complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Due to significant amount of myocardium at risk, donor vessel injury may lead to rapid hemodynamic collapse. In this setting, prompt restoration of blood flow into the donor artery is of paramount importance. Advancement of a safety coronary workhorse guidewire in the donor vessel prior to attempting CTO PCI is a simple maneuver that provides access to the donor artery for rapid coronary intervention and restoration of blood flow, in the event of donor vessel injury. We describe two cases of CTO PCI that illustrate the value of the safety coronary guidewire.

Abstract
INTRODUCTION Little is known about cardiopulmonary resuscitation (CPR) quality during pediatric interhospital transport; hence, our aim was to investigate its feasibility. METHODS After implementing an institutional education curriculum on pediatric resuscitation during ambulance transport, we conducted a 4-year prospective observational study involving simulation events. Simulated scenarios were (1) interhospital transport of a child retrieved in cardiac arrest (Sim1) and (2) unanticipated cardiac arrest of a child during transport (Sim2). Cardiopulmonary resuscitation data were collected via Zoll RSeries defibrillators. Performance was evaluated using age-appropriate American Heart Association (AHA) Guidelines. Video recordings were reviewed for qualitative thematic analysis. RESULTS Twenty-six simulations were included: 16 Sim1 [mannequins: Laerdal SimMan 3G (n = 13); Gaumard 5-year-old HAL (n = 3)] and 10 Sim2 [Gaumard 1-year-old HAL (n = 8); Laerdal SimBaby (n = 2)]. Median (IQR) CPR duration was 18 minutes 23 seconds (14-22 minutes), chest compression rate was 112 per minute (106-118), and fraction (CCF) was 1 (0.9-1). Five hundred eight 60-second resuscitation epochs were evaluated (Sim1: 356; Sim2: 152); 73% were AHA compliant for rate and 87.8% for CCF. Twenty-four minutes (4.7%) had pauses more than 10 seconds. One hundred fifty seven Sim1 epochs (44.1%) met criteria for excellent CPR (AHA-compliant for rate, depth, and CCF). Rates of excellent CPR were higher for learner groups with increased simulation and transport experience (59.1% vs. 35.3%, P < 0.001). Thematic analysis identified performance-enhancing strategies, stemming from anticipating challenges, planning solutions, and ensuring team's shared mental model. CONCLUSIONS High-quality CPR may be achievable during pediatric interhospital transport. Certain transport-specific strategies may enhance resuscitation quality. Learners' performance improved with simulation and transport experience, highlighting ongoing education's role.

Abstract
Mechanical automated compression devices are being used in cardiopulmonary resuscitation instead of manual, “hands-on”, rescuer-delivered chest compressions. The -theoretical- advantages include high-quality non-stop compressions, thus freeing the rescuer performing the compressions and additionally the ability of the rescuer to stand reasonably away from a potentially “hazardous” victim, or from hazardous and/or difficult resuscitation conditions. Such circumstances involve cardiopulmonary resuscitation (CPR) in the Cardiac Catheterization Laboratory, especially directly under the fluoroscopy panel, where radiation is well known to cause detrimental effects to the rescuer, and CPR during/after land or air transportation of cardiac arrest victims. Lastly, CPR in a coronavirus disease 2019 patient/ward, where the danger of contamination and further serious illness of the health provider is very existent. The scope of this review is to review and present literature and current guidelines regarding the use of mechanical compressions in these “hostile” and dangerous settings, while comparing them to manual compressions.

Abstract
INTRODUCTION Cardiopulmonary resuscitation-induced consciousness is a newly recognized phenomenon with an increasing incidence. A return of consciousness during cardiopulmonary resuscitation affects up to 0.9% of cases. Patients may also experience physical pain associated with chest compressions, as most victims of cardiac arrest who are subjected to resuscitative efforts sustain ribs or sternum fractures. METHODS A rapid review was carried out from August 2021 to December 2022. RESULTS Thirty-two articles were included in the rapid review. Of these, eleven studies focused on the return of consciousness during CPR, and twenty-one on CPR-induced chest injuries. CONCLUSION A small number of studies that have dealt with the return of consciousness associated with cardiopulmonary resuscitation made it hard to clearly determine how often this occurs. There were more studies that dealt with chest trauma during resuscitation, but no study considered the use of analgesics. Of note, there was no standardized therapeutic approach as far as the use of analgesics and/or sedatives was considered. This is probably due to the lack of guidelines for analgesic management during cardiopulmonary resuscitation and peri-resuscitative period.

[PMID: 36607514 PMCID: PMC9823175 DOI: 10.1186/s40635-022-00485-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 12/17/2022] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND In refractory out-of-hospital cardiac arrest, transportation to hospital with continuous chest compressions (CCC) from a chest compression device and ventilation with 100% oxygen through an advanced airway is common practice. Despite this, many patients are hypoxic and hypercapnic on arrival, possibly related to suboptimal ventilation due to the counterpressure caused by the CCC. We hypothesized that a compression/ventilation ratio of 30:2 would provide better ventilation and gas exchange compared to asynchronous CCC during prolonged experimental cardiopulmonary resuscitation (CPR). METHODS We randomized 30 anaesthetized domestic swine (weight approximately 50 kg) with electrically induced ventricular fibrillation to the CCC or 30:2 group and bag-valve ventilation with a fraction of inspired oxygen (FiO2) of 100%. We started CPR after a 5-min no-flow period and continued until 40 min from the induction of ventricular fibrillation. Chest compressions were performed with a Stryker Medical LUCAS® 2 mechanical chest compression device. We collected arterial blood gas samples every 5 min during the CPR, measured ventilation distribution during the CPR using electrical impedance tomography (EIT) and analysed post-mortem computed tomography (CT) scans for differences in lung aeration status. RESULTS The median (interquartile range [IQR]) partial pressure of oxygen (PaO2) at 30 min was 110 (52-117) mmHg for the 30:2 group and 70 (40-171) mmHg for the CCC group. The median (IQR) partial pressure of carbon dioxide (PaCO2) at 30 min was 70 (45-85) mmHg for the 30:2 group and 68 (42-84) mmHg for the CCC group. No statistically significant differences between the groups in PaO2 (p = 0.40), PaCO2 (p = 0.79), lactate (p = 0.37), mean arterial pressure (MAP) (p = 0.47) or EtCO2 (p = 0.19) analysed with a linear mixed model were found. We found a deteriorating trend in PaO2, EtCO2 and MAP and rising PaCO2 and lactate levels through the intervention. There were no differences between the groups in the distribution of ventilation in the EIT data or the post-mortem CT findings. CONCLUSIONS The 30:2 and CCC protocols resulted in similar gas exchange and lung pathology in an experimental prolonged mechanical CPR model.

Mathematical Model of Blood Circulation with Compression of the Prototype's Mechanical CPR Waveform. BIOENGINEERING (BASEL, SWITZERLAND) 2022; 9:bioengineering9120802.

Abstract
The waveform of chest compressions directly affects the blood circulation of patients with cardiac arrest. Currently, few pieces of research have focused on the influence of the cardiopulmonary resuscitation (CPR) device's mechanical waveform on blood circulation. This study investigates the effect of the mechanical waveform from a novel CPR prototype on blood circulation and explores the optimal compression parameters of the mechanical waveform to optimize blood circulation. A novel CPR prototype was designed and built to establish a kinetic model during compressions. The prototype's mechanical waveforms at various operating conditions were obtained for comparison with manual waveforms and the investigation of the optimal compression parameters. The novel CPR prototype can complete chest compressions quickly and stably. The cardiac output (CO), coronary perfusion pressure (CPP), and cerebral flow (CF) obtained by mechanical waveform compressions (1.22367 ± 0.00942 L/min, 30.95083 ± 0.24039 mmHg, 0.31992 ± 0.00343 L/min, respectively) were significantly better than those obtained by manual waveform compressions (1.10783 ± 0.03601 L/min, 21.39210 ± 1.42771 mmHg, 0.29598 ± 0.01344 L/min, respectively). With the compression of the prototype, the blood circulation can be optimized at the compression depth of 50 mm, approximately 0.6 duty cycle, and approximately 110 press/min, which is of guiding significance for the practical use of CPR devices to rescue patients with cardiac arrest.

Abstract
Introduction The presented study aimed to investigate whether a mechanical chest compression piston device with a suction cup assisting chest recoil could impact the hemodynamic status when compared to a bare piston during cardiopulmonary resuscitation. Methods 16 piglets were anesthetized and randomized into 2 groups. After 3 minutes of induced ventricular fibrillation, a LUCAS 3 device was used to perform chest compressions, in one group a suction cup was mounted on the device’s piston, while in the other group, compressions were performed by the bare piston. The device was used in 30:2 mode and the animals were manually ventilated. Endpoints of the study were: end tidal carbon dioxide, coronary and cerebral perfusion pressures, and brain oxygenation (measured using near infrared spectroscopy). At the end of the protocol, the animals that got a return to spontaneous circulation were observed for 60 minutes, then euthanized. Results No difference was found in end tidal carbon dioxide or tidal volumes. Coronary perfusion pressure and cerebral oxygenation were higher in the Suction cup group over the entire experiment time, while cerebral perfusion pressure was higher only in the last 5 minutes of CPR. A passive tidal volume (air going in and out the airways during compressions) was detected and found correlated to end tidal carbon dioxide. Conclusions The use of a suction cup on a piston-based chest compression device did not increase end tidal carbon dioxide, but it was associated to a higher coronary perfusion pressure.

Abstract
Objective This study aimed to compare the rates of sustained return of spontaneous circulation (ROSC) between manual and mechanical chest compression in adult non-traumatic cardiac arrest. Methods A retrospective cohort study was conducted from 2017 to 2019. The medical records were reviewed in 227 cardiac arrest patients aged ≥18 years who experienced out-of-hospital cardiac arrest or cardiac arrest while visiting the emergency department (ED). The patients were divided into manual chest compression and mechanical chest compression groups. The two groups were compared in terms of baseline characteristics, time to arrive at the ED, time to basic life support, initial rhythm, time to defibrillation in the shockable group, time to the first dose of adrenaline, and possible cause of arrest. A multivariate logistic regression model was used to determine the factors associated with ROSC. Results A total of 227 patients met the inclusion criteria:193 patients in the manual chest compression group and 34 patients in the mechanical chest compression group. The rate of sustained ROSC in the manual chest compression group was higher (43% vs 8.8%; P < 0.001). The significant factors associated with ROSC were witnessed cardiac arrest (odds ratio (OR) = 3.41; 95% confidence interval (CI) 0.94–12.4), ED arrival by basic ambulance service (OR = 1.93; 95% CI 0.86–4.35), cardiac arrest at the ED (OR = 3.69; 95% CI 1.73–7.88), and cardiac arrest from hypoxia (OR = 2.01; 95% CI 1.02–3.97). Conclusion Mechanical chest compression was not associated with sustained ROSC and tended to be selectively used in patients with a prolonged duration of cardiac arrest.

Abstract
This case series presents patients who presented to the hospital with an outside hospital cardiac arrest and were initially resuscitated successfully. All patients suffered fatal traumatic injuries during the resuscitation process with the common variable being the use of mechanical cardiopulmonary resuscitation (CPR) device. The goal of this case series is to describe the limitations and potential fatal side effects of CPR. We also present a review of literature with our impressions of the appropriate indications for the use of mechanical CPR. Learning objectives 1) Recognize appropriate indications for the use of mechanical vs manual cardiopulmonary resuscitation (CPR). 2) Identify signs and symptoms of mechanical CPR-related complications.

Abstract
BACKGROUND Although high-quality chest compressions are an essential, lifesaving component of cardiopulmonary resuscitation, injuries are common with both manual and mechanical chest compressions. CASE REPORT We discuss the case of a 77-year-old woman who sustained thoracic vertebral fractures after cardiopulmonary resuscitation involving both manual and mechanical chest compressions. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Routine post-cardiac arrest care should include evaluation for chest compression-related injury. If a patient has back pain, focal vertebral tenderness, or paraplegia after chest compressions, imaging to evaluate for vertebral fracture should be performed. If unable to assess for back pain or tenderness, consider imaging to evaluate for vertebral fracture in patients with kyphosis or osteopenia, as these patients are at higher risk for chest compression vertebral injury.

Abstract
Pectus excavatum (PE) is a malformation of the chest characterized by a median depression of the sternum. The incidence of PE is between 0.1% and 0.8%. In the last decade mechanical chest compression devices (MCCD) became of particular interest in cardiopulmonary resuscitation. Different devices became available and this resulted in an increase in their use during CPR mainly for practical reasons. Despite their increasing use, little evidence existed for their effectiveness and little was known about complications. Skin lesions and fractures of sternum or ribs are the ones with the highest incidence. Whereas subdiaphragmatic lesions, in particular fatal liver injuries are uncommon and described only in few case reports. In a recent retrospective study, CT was used to determine the proper compression landmark and depth of cardiopulmonary resuscitation in PE patients. The authors showed that the mean Haller Index in PE patients was higher than in controls, thus exposing internal organs to a higher injury risk during standard CPR maneuvers. We report the first case, to our knowledge, of liver injury during mechanical CPR in a patient with PE. Awareness is being raised on tailoring mechanical CPR in patients with chest deformities. Further exploration is needed to determine if there is a strong correlation between mechanical CPR and organ damage in PE. We believe that this case highlights the importance of individualizing CPR techniques.

Abstract
Aim To determine compression force variation (CFV) during mechanical cardiopulmonary resuscitation (CPR) and its relationship with CPR-related injuries and survival. Methods Adult non-traumatic OHCA patients who had been treated with mechanical CPR were evaluated for CPR-related injuries using chest X-rays, thoracic computed tomography or autopsy. The CFV exerted by the LUCAS 2 device was calculated as the difference between the maximum and the minimum force values and was categorised into three different groups (high positive CFV ≥ 95 newton (N), high negative CFV ≤ -95 N, and low variation for intermediate CFV). The CFV was correlated with the CPR injuries findings and survival data. Results Fifty-two patients were included. The median (IQR) age was 57 (49-66) years, and 13 (25%) cases survived until hospital admission. High positive CFV was found in 21 (40.4%) patients, high negative CFV in 9 (17.3%) and a low CFV in 22 (42.3%). The median (IQR) number of rib fractures was higher in the high positive and negative CFV groups compared with the low CFV group [7(1-9) and 9 (4-11) vs 0 (0-6) (p = 0.021)]. More bilateral fracture cases were found in the high positive and negative CFV groups [16 (76.2%) and 6 (66.7%) vs 6 (27.3%) (p = 0.004)]. In the younger half of the sample more patients survived until hospital admission in the low CFV group compared with the high CFV groups [5 (41.7%) vs 1 (7.1%) (p = 0.037)]. Conclusions High CFV was associated with ribcage injuries. In the younger patients low CFV was associated with survival until hospital admission.

A novel strategy sequentially linking mechanical cardiopulmonary resuscitation with extracorporeal cardiopulmonary resuscitation optimizes prognosis of refractory cardiac arrest: an illustrative case series. Eur J Med Res 2022; 27:77.

Abstract
Background Extracorporeal membrane oxygenation (ECMO) to support cardiopulmonary resuscitation (CPR), also known as extracorporeal cardiopulmonary resuscitation (ECPR), has shown encouraging results in refractory cardiac arrest (RCA) resuscitation. However, its therapeutic benefits are linked to instant and uninterrupted chest compression (CC), besides early implementation. Mechanical CC can overcome the shortcomings of conventional manual CC, including fatigue and labor consumption, and ensure adequate blood perfusion. A strategy sequentially linking mechanical CPR with ECPR may earn extra favorable outcomes. Case series We present a four-case series with ages ranging from 8 to 94 years who presented with prolonged absences of return of spontaneous circulation (ROSC) after CA associated with acute fulminant myocarditis (AFM) and myocardial infarction (MI). All the cases received VA-ECMO (ROTAFLOW, Maquet) assisted ECPR, with intra-aortic balloon pump (IABP) or continuous renal replacement treatment (CRRT) appended if persistently low mean blood pressure (MAP) or ischemic kidney injury occurred. All patients have successfully weaned off ECMO and the assistant life support devices with complete neurological recovery. Three patients were discharged, except the 94-year-old patient who died of irreversible sepsis 20 days after ECMO weaning-off. These encouraging results will hopefully lead to more consideration of this lifesaving therapy model that sequentially integrates mechanical CPR with ECPR to rescue RCA related to reversible cardiac causes. Conclusions This successful case series should lead to more consideration of an integrated lifesaving strategy sequentially linking mechanical cardiopulmonary resuscitation with ECPR, as an extra favorable prognosis of refractory cardiac arrest related to this approach can be achieved.

Abstract
Chest compressions during cardiopulmonary resuscitation (CPR) may be associated with iatrogenic chest wall injuries. The extent to which these CPR-associated chest wall injuries contribute to a delay in the respiratory recovery of cardiac arrest survivors has not been sufficiently explored. In a single-center retrospective cohort study, surviving intensive care unit (ICU) patients, who had undergone CPR due to medical reasons between 1 January 2018 and 30 June 2019, were analyzed regarding CPR-associated chest wall injuries, detected by chest radiography and computed tomography. Among 109 included patients, 38 (34.8%) presented with chest wall injuries, including 10 (9.2%) with flail chest. The multivariable logistic regression analysis identified flail chest to be independently associated with the need for tracheostomy (OR 15.5; 95% CI 2.77−86.27; p = 0.002). The linear regression analysis identified pneumonia (β 11.34; 95% CI 6.70−15.99; p < 0.001) and the presence of rib fractures (β 5.97; 95% CI 1.01−10.93; p = 0.019) to be associated with an increase in the length of ICU stay, whereas flail chest (β 10.45; 95% CI 3.57−17.33; p = 0.003) and pneumonia (β 6.12; 95% CI 0.94−11.31; p = 0.021) were associated with a prolonged duration of mechanical ventilation. Four patients with flail chest underwent surgical rib stabilization and were successfully weaned from the ventilator. The results of this study suggest that CPR-associated chest wall injuries, flail chest in particular, may impair the respiratory recovery of cardiac arrest survivors in the ICU. A multidisciplinary assessment may help to identify patients who could benefit from a surgical treatment approach.

Abstract
Background and Objectives: This study analyzed the prognostic impact of mechanical cardiopulmonary resuscitation (CPR) devices in out-of-hospital cardiac arrest (OHCA) patients, in comparison to manual CPR. Materials and Methods: This study was a nationwide population-based observational study in South Korea. Data were retrospectively collected from 142,905 OHCA patients using the South Korean Out-of-Hospital Cardiac Arrest Surveillance database. We included adult OHCA patients who received manual or mechanical CPR in the emergency room. The primary outcome was survival at discharge and the secondary outcome was sustained return of spontaneous circulation (ROSC). Statistical analysis included propensity score matching and multivariate logistic regression. Results: A total of 19,045 manual CPR and 1125 mechanical CPR cases (671 AutoPulseTM vs. 305 ThumperTM vs. 149 LUCASTM) were included. In the matched multivariate analyses, all mechanical CPR devices were associated with a lower ROSC than that of manual CPR. AutoPulseTM was associated with lower survival in the multivariate analysis after matching (aOR with 95% CI: 0.57 (0.33–0.96)), but the other mechanical CPR devices were associated with similar survival to discharge as that of manual CPR. Witnessed arrest was commonly associated with high ROSC, but the use of mechanical CPR devices and cardiac origin arrest were associated with low ROSC. Only target temperature management was the common predictor for high survival. Conclusions: The mechanical CPR devices largely led to similar survival to discharge as that of manual CPR in OHCA patients; however, the in-hospital use of the AutoPulseTM device for mechanical CPR may significantly lower survival compared to manual CPR.

Manual versus mechanical chest compression in in-hospital cardiac arrest: A retrospective cohort in emergency department patients. Turk J Emerg Med 2022; 22:83-88.

Abstract
OBJECTIVE: Mechanical chest compression (CC) devices are frequently used in in-hospital and out-of-hospital settings. In this study, mechanical and manual CC in in-hospital cardiac arrest was compared in terms of survival. METHODS: Adult patients who were admitted to the emergency department (ED) for 2 years period and had cardiac arrest in the ED were included in this retrospective, observational study. Return of spontaneous circulation (ROSC), 7-day and 30-day survival and hospital discharge data were compared between the two groups of patients who underwent manual CC and those who had mechanical CC with the Lund University Cardiac Assist System-2 device. RESULTS: Although the rate of ROSC in the mechanical CC group was lower than in the manual CC group, this difference was not statistically significant (41.7% vs. 50.4%; P = 0.133). The 7-day survival rate was found to be statistically significantly higher in the mechanical CC group (19.4% vs. 8.9%; P = 0.012). The 30-day survival rate was also found to be high in the mechanical CC group, but this difference was not statistically significant (10.6% vs. 7.3%; P = 0.339). CONCLUSION: In the light of these results, we can say that the use of piston-based mechanical CC devices in ED may be beneficial. More reliable results can be obtained with a prospective study to be performed in the ED.

Mechanical active compression-decompression versus standard mechanical cardiopulmonary resuscitation: A randomised haemodynamic out-of-hospital cardiac arrest study. Resuscitation 2021; 170:1-10. [PMID: 34710550 DOI: 10.1016/j.resuscitation.2021.10.026] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 10/13/2021] [Accepted: 10/15/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Active compression-decompression cardiopulmonary resuscitation (ACD-CPR) utilises a suction cup to lift the chest-wall actively during the decompression phase (AD). We hypothesised that mechanical ACD-CPR (Intervention), with AD up to 30 mm above the sternal resting position, would generate better haemodynamic results than standard mechanical CPR (Control). METHODS This out-of-hospital adult non-traumatic cardiac arrest trial was prospective, block-randomised and non-blinded. We included intubated patients with capnography recorded during mechanical CPR. Exclusion criteria were pregnancy, prisoners, and prior chest surgery. The primary endpoint was maximum tidal carbon dioxide partial pressure (pMTCO2) and secondary endpoints were oxygen saturation of cerebral tissue (SctO2), invasive arterial blood pressures and CPR-related injuries. Intervention device lifting force performance was categorised as Complete AD (≥30 Newtons) or Incomplete AD (≤10 Newtons). Haemodynamic data, analysed as one measurement for each parameter per ventilation (Observation Unit, OU) with non-linear regression statistics are reported as mean (standard deviation). A two-sided p-value < 0.05 was considered as statistically significant. RESULTS Of 221 enrolled patients, 210 were deemed eligible (Control 109, Intervention 101). The Control vs. Intervention results showed no significant differences for pMTCO2: 29(17) vs 29(18) mmHg (p = 0.86), blood pressures during compressions: 111(45) vs. 101(68) mmHg (p = 0.93) and decompressions: 21(20) vs. 18(18) mmHg (p = 0.93) or for SctO2%: 55(36) vs. 57(9) (p = 0.42). The 48 patients who received Complete AD in > 50% of their OUs had higher SctO2 than Control patients: 58(11) vs. 55(36)% (p < 0.001). CONCLUSIONS Mechanical ACD-CPR provided similar haemodynamic results to standard mechanical CPR. The Intervention device did not consistently provide Complete AD.

Safety of mechanical and manual chest compressions in cardiac arrest patients: A systematic review and meta-analysis. Resuscitation 2021; 169:124-135.

Abstract
AIM Summarise the evidence regarding the safety of mechanical and manual chest compressions for cardiac arrest patients. METHODS Two investigators separately screened the articles of EMBASE, PubMed, and Cochrane Central databases. Cohort studies and randomized clinical trials (RCTs) that evaluated the safety of mechanical (LUCAS or AutoPulse) and manual chest compressions in cardiac arrest patients were included. A meta-analysis was performed using a random effects model to calculate the pooled odds ratios (ORs) and their 95% confidence intervals (CIs). The primary outcome was the rate of overall compression-induced injuries. The secondary outcomes included the incidence of life-threatening injuries, skeletal fractures, visceral injuries, and other soft tissue injuries. RESULTS The meta-analysis included 11 trials involving 2,818 patients. A significantly higher rate of overall compression-induced injuries was found for mechanical compressions than manual compressions (OR, 1.29; 95% CI, 1.19-1.41), while there was no significant difference between the two groups in respect of the rate of life-threatening injuries. Furthermore, both modalities shared similar incidences of sternal fractures, vertebral fractures, lung, spleen, and kidney injuries. However, compared to mechanical compressions, manual compressions were shown to present a reduced risk of posterior rib fractures, and heart and liver lesions. CONCLUSIONS The findings suggested that manual compressions could decrease the risk of compression-induced injuries compared to mechanical compressions in cardiac arrest patients. Interestingly, mechanical compressions have not increased the risk of life-threatening injuries, whereas additional high-quality RCTs are needed to further verify the safety of mechanical chest devices.

Abstract
PURPOSE Mechanical chest compression has been shown to be equivalent to manual chest compression in providing survival benefits to patients experiencing cardiac arrest. There has been a growing need for a contemporary review of iatrogenic injuries caused by mechanical in comparison with manual chest compression. Our study aims to analyze the studies that document significant life-threatening iatrogenic injuries caused by mechanical and manual chest compression. METHODS A systematic review of PubMed and Embase was performed according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. All studies published after January 1st, 2000 were reviewed using inclusion/exclusion criteria and completed by May 2020. A total of 7202 patients enrolled in 15 studies were included in our meta-analysis. RESULTS Significant life-threatening iatrogenic injuries had higher odds of occurring when mechanical chest compression was used compared to manual chest compression, especially for hemothorax and liver lacerations. Mechanical chest compression involves consistently deeper compression depths compared to manual chest compression, potentially resulting in more injuries. In the mechanical chest compression cohort, chest wall fractures had the highest incidence rate (55.7%), followed by sternal fracture (28.3%), lung injuries (3.7%), liver (1.0%), and diaphragm (.2%) lacerations. CONCLUSIONS Mechanical chest compression was associated with more iatrogenic injuries as compared to manual chest compression. Further research is needed to define the appropriate application of mechanical in comparison with manual chest compression in different scenarios. Levels of provider training, different mechanical chest compression device types, patient demographics, and compression duration/depth may all play roles in influencing outcomes.

Abstract
Out-of-hospital cardiac arrest (OHCA) is a major healthcare problem, with approximately 200 weekly cases in the Netherlands. Its critical, time-dependent nature makes it a unique medical situation, of which outcomes strongly rely on infrastructural factors and on-scene care by emergency medical services (EMS). Survival to hospital discharge is poor, although it has substantially improved, to roughly 25% over the last years. Recognised key factors, such as bystander resuscitation and automated external defibrillator use at the scene, have been markedly optimised with the introduction of technological innovations. In an era with ubiquitous smartphone use, the Dutch digital text message alert platform HartslagNu (www.hartslagnu.nl) increasingly contributes to timely care for OHCA victims. Guidelines emphasise the role of cardiac arrest recognition and early high-quality bystander resuscitation, which calls for education and improved registration at HartslagNu. As for EMS care, new technological developments with future potential are the selective use of mechanical chest compression devices and extracorporeal life support. As a future innovation, ‘smart’ defibrillators are under investigation, guiding resuscitative interventions based on ventricular fibrillation waveform characteristics. Taken together, optimisation of available prehospital technologies is crucial to further improve OHCA outcomes, with particular focus on more available trained volunteers in the first phase and additional research on advanced EMS care in the second phase.

Abstract
Introduction Our goal was to systematically review contemporary literature comparing the relative effectiveness of two mechanical compression devices (LUCAS and AutoPulse) to manual compression for achieving return of spontaneous circulation (ROSC) in patients undergoing cardiopulmonary resuscitation (CPR) after an out-of-hospital cardiac arrest (OHCA). Methods We searched medical databases systematically for randomized controlled trials (RCT) and observational studies published between January 1, 2000–October 1, 2020 that compared mechanical chest compression (using any device) with manual chest compression following OHCA. We only included studies in the English language that reported ROSC outcomes in adult patients in non-trauma settings to conduct random-effects metanalysis and trial sequence analysis (TSA). Multivariate meta-regression was performed using preselected covariates to account for heterogeneity. We assessed for risk of biases in randomization, allocation sequence concealment, blinding, incomplete outcome data, and selective outcome reporting. Results A total of 15 studies (n = 18474), including six RCTs, two cluster RCTs, five retrospective case-control, and two phased prospective cohort studies, were pooled for analysis. The pooled estimates’ summary effect did not indicate a significant difference (Mantel-Haenszel odds ratio = 1.16, 95% confidence interval, 0.97 to 1.39, P = 0.11, I2 = 0.83) between mechanical and manual compressions during CPR for ROSC. The TSA showed firm evidence supporting the lack of improvement in ROSC using mechanical compression devices. The Z-curves successfully crossed the TSA futility boundary for ROSC, indicating sufficient evidence to draw firm conclusions regarding these outcomes. Multivariate meta-regression demonstrated that 100% of the between-study variation could be explained by differences in average age, the proportion of females, cardiac arrests with shockable rhythms, witnessed cardiac arrest, bystander CPR, and the average time for emergency medical services (EMS) arrival in the study samples, with the latter three attaining statistical significance. Conclusion Mechanical compression devices for resuscitation in cardiac arrests are not associated with improved rates of ROSC. Their use may be more beneficial in non-ideal situations such as lack of bystander CPR, unwitnessed arrest, and delayed EMS response times. Studies done to date have enough power to render further studies on this comparison futile.

Abstract
INTRODUCTION The recommended method of cardiopulmonary resuscitation (CPR) has been closed-chest cardiac compressions, but the development of CPR adjunctive devices has called into question the efficacy and role of these adjunctive devices. In this review, we provide a comprehensive evaluation and discussion on the commercially available noninvasive CPR adjuncts used during out-of-hospital cardiac arrest (OHCA). AREAS COVERED We review the three most common CPR adjunctive devices: the piston mechanism, the load distributing band, and the impedance threshold device. All three CPR adjunctive devices have preclinical data to support their use during cardiac arrest. In clinical trials, limited data show improvement in survival and neurologic recovery for these devices, and there is insufficient high-level evidence to support their use over manual chest compressions. However, there is a role for them when adequate manual chest compressions are not feasible. EXPERT OPINION The commercially available CPR adjuncts do not consistently show improved outcomes in the literature. There is still a need for research and development into innovative solutions to improve OHCA survival and neurologic recovery. Efforts focused on increasing the speed of CPR initiation and increasing perfusion to the cerebral and coronary vasculature have the potential to advance resuscitative practices.

Abstract
Research regarding the use of mechanical compressions in the setting of a cardiac arrest, either outside of or inside the hospital environment has produced mixed results. The debate whether they can replace manual compressions still remains. The aim of this review is to present current literature contemplating the application of mechanical compressions in both settings, data comparing them to manual compressions as well as current guidelines regarding their implementation in everyday clinical use. Currently, their implementation in the resuscitation protocol seems to benefit the victims of an in-hospital cardiac arrest rather than the victims that sustain a cardiac arrest outside of the hospital.

Abstract
OBJECTIVE To identify and compare manual and load-distributing band (LDB) cardiopulmonary resuscitation (CPR)-related injuries. METHODS Retrospective observational cohort study. Adult, nontraumatic deaths with a postmortem computed tomography scan (PMCT) performed were classified into two groups: deceased after LDB CPR or after manual CPR. PMCT scans were reviewed for thoracoabdominal injuries such as fractures, pneumothorax and hemorrhage. The injuries between groups were compared. RESULTS LDB CPR (n = 43) showed increased incidences of posterior rib fractures (53 vs 18%, P = 0.006), pneumothorax (23 vs 4%, P = 0.04) and more pericardial fluid (median 12 vs 6 mm, P = 0.002) compared with manual CPR (n = 29). Multivariable regression analysis revealed that LDB CPR was significantly associated with posterior rib fractures [odds ratio (OR) 5.37, 95% confidence interval (CI): 1.44-20.09, P = 0.01). Pneumothorax (OR 6.80, 95% CI: 0.73-62.99, P = 0.09) and the amount of pericardial fluid (OR 3.40, 95% CI: 0.20-56.32) were not significantly associated with LDB CPR. No significant difference was found for anterolateral rib fractures, sternal fractures, vertebral fractures, pleural fluid, hemothorax, hemopericardium, pneumoperitoneum, perihepatic, perisplenic and perirenal hemorrhage. CONCLUSION Rib fractures, sternal fractures, hemothorax and hemopericardium are common CPR-related injuries. LDB CPR is significantly associated with more posterior rib fractures and a trend toward more pneumothoraces is observed when compared with manual CPR. This knowledge is important for caretakers in the case of ongoing CPR, as a pneumothorax may attribute to not achieving persistent return of spontaneous circulation, and to improve postresuscitation care of survivors.

Abstract
Sudden cardiac death is a leading cause of death worldwide, whereby myocardial infarction is considered the most frequent underlying condition. Percutaneous coronary intervention (PCI) is an important component of post-resuscitation care, while uninterrupted high-quality chest compressions are key determinants in cardiopulmonary resuscitation (CPR). In our paper, we evaluate a case of a female patient who suffered aborted cardiac arrest due to myocardial infarction. The ambulance crew providing prehospital care for sudden cardiac arrest used a mechanical chest compression device during advanced CPR, which enabled them to deliver ongoing resuscitation during transfer to the PCI laboratory located 20 km away from the scene. Mechanical chest compressions were continued during the primary coronary intervention. The resuscitation, carried out for 2 h and 35 min, and the coronary intervention were successful, as evidenced by the return of spontaneous circulation and by the fact that, after a short rehabilitation, the patient was discharged home with a favorable neurological outcome. Our case can serve as an example for the effective and safe use of a mechanical compression device during primary coronary intervention.

Abstract
BACKGROUND Mechanical chest compression devices are accepted alternatives for cardiopulmonary resuscitation (CPR) under specific circumstances. Current devices lack prospective and comparative data on their specific cardiovascular effects and potential for severe thoracic injuries. OBJECTIVES To compare CPR effectiveness and thoracic injuries of two mechanical chest compression devices in pigs. STUDY DESIGN Prospective randomised trial. ANIMALS Eighteen male German landrace pigs. METHODS Ventricular fibrillation was induced in anaesthetised and instrumented pigs and the animals were randomised into two intervention groups. Mechanical CPR was initiated by means of LUCAS™ 2 (mCCD1) or Corpuls™ cpr (mCCD2) device. Advanced life support was applied for a maximum of 10 cycles and animals achieving ROSC were monitored for 8 h. Ventilation/perfusion measurements were performed and blood gas analyses were taken. Thoracic injuries were assessed via a standardised damage score. RESULTS Five animals of the mCCD1 group and one animal of the mCCD2 group achieved ROSC (p = 0.048). Only the mCCD1 animals survived until the end of the monitoring period (p < 0.01). MCCD1 animals showed less pulmonary shunt (p = 0.025) and higher normal V/Q (p = 0.017) during CPR. MCCD2 animals showed significantly more severe thoracic injuries (p = 0.046). CONCLUSION The LUCAS 2 device shows superior resuscitation outcomes and less thoracic injuries compared to Corpuls cpr when used for experimental CPR in juvenile pigs. Researchers should be aware that different mCCDs for experimental studies may significantly influence the respective outcome of resuscitation studies and affect comparability of different trials. Controlled human and animal CPR studies and a standardised post-resuscitation injury evaluation could help to confirm potential hazards. TRIAL REGISTRATION Trial approval number: G16-1-042-E4.

Abstract
Background There are data suggesting that passive leg raising (PLR) improves hemodynamics during cardiopulmonary resuscitation (CPR). This trial aimed to determine the effectiveness and safety of PLR during CPR in out-of-hospital cardiac arrest (OHCA).
Methods We conducted a randomized controlled trial with blinded assessment of the outcomes that assigned adults OHCA to be treated with PLR or in the flat position. The trial was conducted in the Camp de Tarragona region. The main end point was survival to hospital discharge with good neurological outcome defined as cerebral performance category (CPC 1–2). To study possible adverse effects, we assessed the presence of pulmonary complications on the first chest X-rays, brain edema on the computerized tomography (CT) in survivors and brain and lungs weights from autopsies in non-survivors. Results In total, 588 randomized cases were included, 301 were treated with PLR and 287 were controls. Overall, 67.8% were men and the median age was 72 (IQR 60–82) years. At hospital discharge, 3.3% in the PLR group and 3.5% in the control group were alive with CPC 1–2 (OR 0.9; 95% CI 0.4–2.3, p = 0.91). No significant differences in survival at hospital admission were found in all patients (OR 1.0; 95% CI 0.7–1.6, p = 0.95) and among patients with an initial shockable rhythm (OR 1.7; 95% CI 0.8–3.4, p = 0.15). There were no differences in pulmonary complication rates in chest X-rays [7 (25.9%) vs 5 (17.9%), p = 0.47] and brain edema on CT [5 (29.4%) vs 10 (32.6%), p = 0.84]. There were no differences in lung weight [1223 mg (IQR 909–1500) vs 1239 mg (IQR 900–1507), p = 0.82] or brain weight [1352 mg (IQR 1227–1457) vs 1380 mg (IQR 1255–1470), p = 0.43] among the 106 autopsies performed. Conclusion In this trial, PLR during CPR did not improve survival to hospital discharge with CPC 1–2. No evidence of adverse effects has been found.

Abstract
Introduction Cardiopulmonary resuscitation (CPR)-related injuries are complications of chest compressions during CPR. This study aimed to investigate the differences and complications between mechanical and manual CPR techniques by using computed tomography (CT). Methods Patients in whom return of spontaneous circulation was achieved after CPR and thorax CT imaging were performed for diagnostic purposes were included in the study. Results A total of 178 non-traumatic cardiac arrest patients were successfully resuscitated and had CT scans in the emergency department. The complications of CPR are sternum fracture, rib fracture, pleural effusion/hemothorax, and pneumothorax. There were no statistically significant differences in terms of age, first complaint, cardiac arrest rhythm, CPR duration, and complications between mechanical and manual CPR. The number of exitus in the emergency department was similar (p=0.638). The discharge from hospital rate was higher in the mechanical CPR group but there was no statistically significant difference (p=0.196). The duration of CPR was associated with the number of rib fractures and lung contusion, but it did not affect other CPR-related chest injuries. Conclusion There was no significant difference observed in terms of increased complications in patients who received mechanical compression as compared with those who received manual compression. According to our results, mechanical compression does not cause serious complications, and the discharge from hospital rate was higher than for manual CPR; therefore, its use should be encouraged.

Abstract
PURPOSE OF REVIEW The purpose of this narrative review is to provide an update on hemodynamics during cardiopulmonary resuscitation (CPR) and to describe emerging therapies to optimize perfusion. RECENT FINDINGS Cadaver studies have shown large inter-individual variations in blood distribution and anatomical placement of the heart during chest compressions. Using advanced CT techniques the studies have demonstrated atrial and slight right ventricular compression, but no direct compression of the left ventricle. A hemodynamic-directed CPR strategy may overcome this by allowing individualized hand-placement, drug dosing, and compression rate and depth. Through animal studies and one clinical before-and-after study head-up CPR has shown promising results as a potential strategy to improve cerebral perfusion. Two studies have demonstrated that placement of an endovascular balloon occlusion in the aorta (REBOA) can be performed during ongoing CPR. SUMMARY Modern imaging techniques may help increase our understanding on the mechanism of forward flow during CPR. This could provide new information on how to optimize perfusion. Head-up CPR and the use of REBOA during CPR are novel methods that might improve cerebral perfusion during CPR; both techniques do, however, still await clinical testing.

Abstract
INTRODUCTION AIM:: To compare injuries after cardiopulmonary resuscitation (CPR) caused by manual or mechanical chest compressions in resuscitated patients with non-traumatic cardiac arrest. METHODS This retrospective, multicenter study was based on autopsy reports of patients who died after CPR; individuals with a traumatic cause(s) of cardiac arrest were excluded. Patients were divided into two CPR groups: mechanical and manual. The Abbreviated Injury Scale was used to objectively evaluate the most serious injuries and the New Injury Scale Score was used to summarize all injuries. RESULTS Of 704 patients, data from 630 individuals were analyzed after exclusion of those with trauma-related cardiac arrest. Manual CPR was performed in 559 patients and mechanical in 64 subjects. There were no differences in sex, bystander CPR, or etiology of cardiac arrest between the two groups, however, mechanical CPR was significantly longer (X vs. Y, p = 0.0005) and patients in this group were younger (X vs. Y, p = 0.0067). No differences were found in the incidence of CPR-related injuries between the groups. The median number of the most serious injury (according to Abbreviated Injury Scale) was 3, which was not statistically different; the median number of injuries according to the New Injury Severity Score was 13 in both groups (low probability of fatal injury). Type of injuries were also similar with the exception of pericardial damage that was more prevalent in mechanical CPR group. Only age and bystander CPR were found to be independently associated with the autopsy-documented trauma. CONCLUSION Our results suggest that mechanical chest compressions do not increase the incidence and severity of CPR-related injury in comparison with manual methods despite significantly longer CPR duration.

Abstract
Rationale: Cardiopulmonary resuscitation is the cornerstone of cardiac arrest (CA) treatment. However, lung injuries associated with it have been reported.Objectives: To assess 1) the presence and characteristics of lung abnormalities induced by cardiopulmonary resuscitation and 2) the role of mechanical and manual chest compression (CC) in its development.Methods: This translational study included 1) a porcine model of CA and cardiopulmonary resuscitation (n = 12) and 2) a multicenter cohort of patients with out-of-hospital CA undergoing mechanical or manual CC (n = 52). Lung computed tomography performed after resuscitation was assessed qualitatively and quantitatively along with respiratory mechanics and gas exchanges.Measurements and Main Results: The lung weight in the mechanical CC group was higher compared with the manual CC group in the experimental (431 ± 127 vs. 273 ± 66, P = 0.022) and clinical study (1,208 ± 630 vs. 837 ± 306, P = 0.006). The mechanical CC group showed significantly lower oxygenation (P = 0.043) and respiratory system compliance (P < 0.001) compared with the manual CC group in the experimental study. The variation of right atrial pressure was significantly higher in the mechanical compared with the manual CC group (54 ± 11 vs. 31 ± 6 mm Hg, P = 0.001) and significantly correlated with lung weight (r = 0.686, P = 0.026) and respiratory system compliance (r = -0.634, P = 0.027). Incidence of abnormal lung density was higher in patients treated with mechanical compared with manual CC (37% vs. 8%, P = 0.018).Conclusions: This study demonstrated the presence of cardiopulmonary resuscitation-associated lung edema in animals and in patients with out-of-hospital CA, which is more pronounced after mechanical as opposed to manual CC and correlates with higher swings of right atrial pressure during CC.

Abstract
DISCLAIMER Veno-arterial extracorporeal membrane oxygenation (ECMO) is increasingly being deployed for selected patients in cardiac arrest who do not attain a native circulation with conventional CPR (ECPR). This ELSO guideline is intended to be a practical guide to implementing ECPR and the early management following establishment of ECMO support. Where a paucity of high-quality evidence exists, a consensus has been reached amongst the authors to provide guidance to the clinician. This guideline will be updated as further evidence in this field becomes available.

Abstract
Background Limited epidemiological data are available on the outcomes of in‐hospital cardiac arrest (CA) in COVID‐19 patients. Methods We performed literature search of PubMed, EMBASE, Cochrane, and Ovid to identify research articles that studied outcomes of in‐hospital cardiac arrest in COVID‐19 patients. The primary outcome was survival at discharge. Secondary outcomes included return of spontaneous circulation (ROSC) and types of cardiac arrest. Pooled percentages with a 95% confidence interval (CI) were calculated for the prevalence of outcomes. Results A total of 7,891 COVID patients were included in the study. There were 621 (pooled prevalence 8%, 95% CI 4–13%) cardiac arrest patients. There were 52 (pooled prevalence 3.0%; 95% CI 0.0–10.0%) patients that survived at the time of discharge. ROSC was achieved in 202 (pooled prevalence 39%;95% CI 21.0–59.0%) patients. Mean time to ROSC was 7.74 (95% CI 7.51–7.98) min. The commonest rhythm at the time of cardiac arrest was pulseless electrical activity (pooled prevalence 46%; 95% 13–80%), followed by asystole (pooled prevalence 40%; 95% CI 6–80%). Unstable ventricular arrhythmia occurred in a minority of patients (pooled prevalence 8%; 95% CI 4–13%). Conclusion This pooled analysis of studies showed that the survival post in‐hospital cardiac arrest in COVID patients is dismal despite adequate ROSC obtained at the time of resuscitation. Nonshockable rhythm cardiac arrest is commoner suggesting a non‐cardiac cause while cardiac related etiology is uncommon. Future studies are needed to improve the survival in these patients.

Abstract
CME: Mechanical Assist Devices in Cardiopulmonary Resuscitation Abstract. Early high-quality cardiopulmonary resuscitation in the event of a cardiac arrest is the most effective measure to improve the outcome. With the aim of improving the quality of resuscitation and replacing the need of manual compression, various mechanical assist devices have been developed and are used in the clinical practice. When should they be used, whether do they lead to better outcomes and what injuries are they associated with? These questions have been examined in several studies and the following review will provide an overview.

Abstract
BACKGROUND With the "Artemis"-mission mankind will return to the Moon by 2024. Prolonged periods in space will not only present physical and psychological challenges to the astronauts, but also pose risks concerning the medical treatment capabilities of the crew. So far, no guideline exists for the treatment of severe medical emergencies in microgravity. We, as a international group of researchers related to the field of aerospace medicine and critical care, took on the challenge and developed a an evidence-based guideline for the arguably most severe medical emergency - cardiac arrest. METHODS After the creation of said international group, PICO questions regarding the topic cardiopulmonary resuscitation in microgravity were developed to guide the systematic literature research. Afterwards a precise search strategy was compiled which was then applied to "MEDLINE". Four thousand one hundred sixty-five findings were retrieved and consecutively screened by at least 2 reviewers. This led to 88 original publications that were acquired in full-text version and then critically appraised using the GRADE methodology. Those studies formed to basis for the guideline recommendations that were designed by at least 2 experts on the given field. Afterwards those recommendations were subject to a consensus finding process according to the DELPHI-methodology. RESULTS We recommend a differentiated approach to CPR in microgravity with a division into basic life support (BLS) and advanced life support (ALS) similar to the Earth-based guidelines. In immediate BLS, the chest compression method of choice is the Evetts-Russomano method (ER), whereas in an ALS scenario, with the patient being restrained on the Crew Medical Restraint System, the handstand method (HS) should be applied. Airway management should only be performed if at least two rescuers are present and the patient has been restrained. A supraglottic airway device should be used for airway management where crew members untrained in tracheal intubation (TI) are involved. DISCUSSION CPR in microgravity is feasible and should be applied according to the Earth-based guidelines of the AHA/ERC in relation to fundamental statements, like urgent recognition and action, focus on high-quality chest compressions, compression depth and compression-ventilation ratio. However, the special circumstances presented by microgravity and spaceflight must be considered concerning central points such as rescuer position and methods for the performance of chest compressions, airway management and defibrillation.

Abstract
We describe a hepatic laceration and subsequent anterior spinal artery syndrome in a 21-year-old man, secondary to prolonged cardiopulmonary resuscitation with a Lund University Cardiac Assist System (LUCAS2) mechanical cardiac compression device. We briefly review the current literature pertaining to hepatic injury from trauma due to cardiopulmonary resuscitation. The etiology of the anterior spinal artery syndrome in this patient is discussed. This case highlights that intra-abdominal causes of hypotension should be considered in patients after a prolonged resuscitation attempt. Extending focused cardiac ultrasound to exclude intra-abdominal free fluid should be routinely considered in these patients.
