Each year in the United States more than 300,000 people die from an out of hospital cardiac arrest (where the heart stops beating). Unfortunately, cardiac arrest kills more than 90% of victims before they reach hospital. (1)
Early cardiopulmonary resuscitation is key to improving survival rates from a cardiac arrest. Without bystander CPR (before an ambulance arrives), the survival rate is as low as 2%. With early CPR, this survival rate rises to 5 - 10% (2).
Combined with early defibrillation, the survival rate can rise to as much as 30%.
Brain damage occurs 4 minutes after a cardiac arrest with no bystander CPR. (3)
