Review Meta Analysis
Bystander Automated External Defibrillator Use and Clinical Outcomes after Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis.
To systematically review studies comparing bystander automated external defibrillator (AED) use to no AED use in regard to clinical outcomes in out-of-hospital cardiac arrest (OHCA), and to provide a descriptive summary of studies on the cost-effectiveness of bystander AED use. ⋯ The evidence supports the association between bystander AED use and improved clinical outcomes, although the quality of evidence was low to very low.

Multicenter Study
Post-Resuscitation Arterial Oxygen and Carbon Dioxide and Outcomes after Out-of-Hospital Cardiac Arrest.
To determine if arterial oxygen and carbon dioxide abnormalities in the first 24h after return of spontaneous circulation (ROSC) are associated with increased mortality in adult out-of-hospital cardiac arrest (OHCA). ⋯ In the first 24h after ROSC, abnormal post-arrest oxygen and carbon dioxide tensions are associated with increased out of-hospital cardiac arrest mortality.

Amplitude spectrum area (AMSA) of ventricular fibrillation (VF) has been associated with survival from out-of-hospital cardiac arrest (OHCA). Ischemic heart disease has been shown to change AMSA. We studied whether the association between AMSA and survival changes with acute ST-elevation myocardial infarction (STEMI) as cause of the OHCA and/or previous MI. ⋯ The prognostic value of AMSA is altered by the presence of STEMI: while AMSA has strong predictive value in patients without STEMI, AMSA is not a predictor of survival in STEMI-patients.
