Review Meta Analysis
Cardiopulmonary resuscitation quality and patient survival outcome in cardiac arrest: a systematic review and meta-analysis.
To conduct a systematic review and meta-analysis to determine whether cardiopulmonary resuscitation (CPR) quality, as indicated by parameters such as chest compression depth, compression rate and compression fraction, is associated with patient survival from cardiac arrest. ⋯ Chest compression depth and rate were associated with survival outcomes. More studies with consistent reporting of data are required for other quality parameters.

Review Meta Analysis
Mechanical chest compression for out of hospital cardiac arrest: Systematic review and meta-analysis.
This review of five trials investigating the efficacy of mechanical CPR devices (the LUCAS & AutoPulse) concluded that the devices demonstrate no outcome advantage compared with manual CPR, in terms of 30 day survival, survival to discharge, or neurological outcome.

Review Meta Analysis
Cerebral oximetry and return of spontaneous circulation after cardiac arrest: a systematic review and meta-analysis.
The prediction of return of spontaneous circulation (ROSC) during resuscitation of patients suffering of cardiac arrest (CA) is particularly challenging. Regional cerebral oxygen saturation (rSO2) monitoring through near-infrared spectrometry is feasible during CA and could provide guidance during resuscitation. ⋯ Higher initial and average regional cerebral oxygen saturation values are both associated with greater chances of achieving ROSC in patients suffering of CA. A note of caution should be made in interpreting these results due to the small number of patients and the heterogeneity in study design: larger studies are needed to clinically validate cut-offs for guiding cardiopulmonary resuscitation.

Review Meta Analysis
Gender and Survival after Sudden Cardiac Arrest A Systematic Review and Meta-Analysis.
Conflicting results exist regarding the impact of gender on early survival after sudden cardiac arrest (SCA). We aimed to assess the association between female gender and early SCA survival. ⋯ This meta-analysis of observational studies demonstrates that women have increased odds of survival after SCA. Further studies are needed to address mechanisms explaining this discrepancy.

Review Meta Analysis
Endotracheal Intubation versus Supraglottic Airway Placement in Out-of-Hospital Cardiac Arrest: A Meta-Analysis.
Overall survival from out-of-hospital cardiac arrest (OHCA) is less than 10%. After initial bag-valve mask ventilation, 80% of patients receive an advanced airway, either by endotracheal intubation (ETI) or placement of a supraglottic airway (SGA). The objective of this meta-analysis was to compare patient outcomes for these two advanced airway methods in OHCA patients treated by Emergency Medical Services (EMS). ⋯ Patients with OHCA who receive ETI by EMS are more likely to obtain ROSC, survive to hospital admission, and survive neurologically intact when compared to SGA.
