Sudden cardiac arrest (SCA) is a leading cause of death in the United States and Canada. This statement provides recommendations to increase rates of bystander cardiopulmonary resuscitation (CPR).

It concludes that to maximize the chance of a successful resuscitation outcome, CPR must be started as soon as possible after a victim of sudden cardiac arrest collapses. Improved survival rates depend on a public trained and motivated to recognize the emergency, activate emergency medical services or the emergency response system, initiate high-quality CPR, and use an automated external defibrillator if available.
