Police vehicles equipped with automated external defibrillators in North America
Every year sudden cardiac arrest (SCA) kills between 35,000 and 45,000 people in Canada and approximately 350,000 people in the United States; 85% of SCAs are caused by ventricular fibrillation (VF). Receiving defibrillation from an automated external defibrillator (AED) is a key component of the 'chain of survival' for victims of SCA. Chances of survival from a SCA decrease by 7–10% every minute that a victims does not receive defibrillation. Attempts at reducing time until defibrillation have largely focused on improving traditional emergency medical service (EMS) responders and implementing publicly available defibrillator (PAD) programs. In the United States approximately 60% of SCAs are treated by EMS.〔 Equipping police vehicles with AEDs and incorporating them in the emergency dispatching process when a SCA is suspected, can reduce the time until defibrillation for a victim suffering an out-of-hospital sudden cardiac arrest. There are numerous studies which confirm a strong coloration between equipping police vehicles with AEDs and reduced time until defibrillation which ultimately translates into improved survival rates from SCA. As a result of these demonstrable statistics, police departments across North America have begun equipping some or all of their police vehicles with AEDs.

In the 1990s three extensive studies, which examined different elements of police AED programs, occurred in Allegheny County PA , Rochester MN and Miami FL. The purpose of these studies was to examine the effectiveness of equipping police with AEDs, their ability to provide reduced response times in rural and suburban communities and how this translates to improved survival rates from SCA. The police departments which originally took part in these studies retained their adopted capabilities and now contribute to some of the highest survival rates from SCA in the country.
