Cardiac arrest is a leading cause of death in the United States. Each year, emergency medical services (EMS) treats about 360,000 victims of cardiac arrest before they reach the hospital. Less than 10 percent of those victims survive. Cardiac arrest can happen to anyone at any time. Placing automated external defibrillators (AEDs) in key locations, and making sure employees are trained to use them, can mean the difference between life and death. Places such as offices, airports, schools, shopping malls, grocery stores, manufacturing plants and golf courses are being equipped with AEDs.
