Automated external defibrillators: Do you need an AED?

Content

By Mayo Clinic Staff

An automated external defibrillator (AED) is a device that can be used to treat a person whose heart has suddenly stopped beating and pumping blood. This condition is called sudden cardiac arrest.

AEDs are available in many public places, such as schools, airports and other community spaces. Small, lightweight AEDs are available without a prescription for use at home.

People who are at risk of sudden cardiac arrest might think about having an AED at home. Talk with your healthcare professional about whether you should buy an AED for your home.
