Having an AED nearby when needed

Police and ambulance crews carry AEDs. Also, they're commonly found in many public places, such as malls, office buildings, schools, sports arenas, gyms and airplanes. But many cardiac arrests occur at home. Having a home AED may save precious minutes in treating a person who has a sudden cardiac arrest.

Supporters of home AEDs say putting them where they're needed most will save many lives. But critics argue there's not enough evidence to show that home AEDs save more lives.
