<p>Approximately 360000 persons suffer out-of-hospital cardiac arrest (OHCA) annually in the United States , and high-quality cardiopulmonary resuscitation (CPR) is the cornerstone of prehospital resuscitation . Real-time feedback devices improve CPR quality  but are typically an accessory to the monitor/defibrillator and not available to the lay public. Instead, the lay public is taught to “push hard and fast” without any provision for real-time feedback to optimize performance . Bystander CPR provides a key link in the chain of survival : communities with higher rates of bystander CPR enjoy commensurate improvements in OHCA survival [2,6], and 1 additional life is saved for every 30 OHCA victims who receive bystander CPR .</p>
