Review Meta Analysis
Monophasic and Biphasic Shock for Transthoracic Conversion of Atrial Fibrillation: Systematic Review and Network Meta-analysis.
Conduct a systematic review of the literature to compare the efficacy of different biphasic and monophasic shock waveforms technologies for transthoracic cardioversion of Atrial Fibrillation (AF). ⋯ The evidences points to a Biphasic waveform superiority over Monophasic to perform AF cardioversion, supporting current guidelines to use less energy when using a Biphasic defibrillator. It is suggested that the Biphasic defibrillators from PhysioControl ADAPTIV, Philips SMART and ZOLL Rectilinear have similar efficacy and the use of any of them may result in similar chances, energy and number of shocks to achieve successful AF cardioversion.

Review Meta Analysis
When should chest compressions be paused to analyze the cardiac rhythm?: A systematic review and meta-analysis.
Most guidelines recommend pausing chest compressions at 2 min intervals to analyze the cardiac rhythm. We conducted a systematic review and meta-analysis to define the optimal interval at which to pause chest compressions in adults for cardiac rhythm analysis in any setting. ⋯ There is a paucity of quality evidence to support pausing chest compressions at any singular interval to assess the cardiac rhythm in adults in cardiac arrest in any setting. Very low-quality evidence suggests improved clinical outcomes in patients receiving 200-compression intervals compared with 1- or 3 min intervals.

Review Meta Analysis
The association of gasping and outcome, in out of hospital cardiac arrest: A systematic review and meta-analysis.
Gasping is common after cardiac arrest, and its frequency decreases over time. The aim of this study was to conduct a meta-analysis to evaluate the association of gasping and survival to discharge in patients who suffered out-of-hospital cardiac arrest. ⋯ Findings of this meta-analysis demonstrated that gasping is common after cardiac arrest, and is associated with increased survival to discharge. Patients who are cardiac arrest with gasping should be promptly resuscitated.

Review Meta Analysis
The Efficacy and Safety of Prehospital Therapeutic Hypothermia in Patients with Out-of-hospital cardiac arrest: A Systematic Review and Meta-Analysis.
The benefit of therapeutic hypothermia (TH) to patients suffering out-of-hospital cardiac arrest (OHCA) has been well established. However, the effect of prehospital cooling remains unclear. We aimed to investigate the efficacy and safety of prehospital TH for OHCA patients by conducting a systematic review of randomised controlled trials (RCTs). ⋯ Evidence does not support the administration of prehospital TH to patients with OHCA.

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.
