Audiovisual Feedback on Out-of-Hospital Cardiopulmonary Resuscitation Quality and Survival From Out-of-Hospital Cardiac Arrest

INTRODUCTION Background and Importance Communities in North America report wide disparities in outcomes from out-of-hospital cardiac arrest. 1’2Although many report poor outcomes, several have achieved significantly higher survival rates 1’2that are likely a result of multiple factors, with one possible component being out-of-hospital cardiopulmonary resuscitation (CPR) quality. There is preclinical and clinical evidence demonstrating that high-quality CPR (defined by the hemodynamically important components chest compression depth, 3 chest compression fraction, 813 preshock pause,’ 4chest compression release velocity [‘recoil”j,’ 715 chest compression rate, and ventilation 21 )improves outcomes. Although the 2010 American Heart Association (AHA) Guidelines place a clear emphasis on minimally interrupted, high-quality CPR, it remains to be determined whether individual communities can improve Study objective: We assess whether an initiative to optimize out-of-hospital provider cardiopulmonary resuscitation (CPR) quality is associated with improved CPR quality and increased survival from out-of-hospital cardiac arrest.
