Automated External Defibrillator (AED)

Last updated: May 17, 2017

What Does Automated External Defibrillator (AED) Mean?

An automated external defibrillator (AED) is a small portable device that is used to correct abnormal activity in the heart by delivering an electrical shock to certain cardiac rhythms. The device analyzes heart rhythms to determine if the rhythm can be corrected by defibrillation. If the rhythm is shockable, the machine will deliver a shock. If the rhythm is not shockable, the machine will not deliver a shock and advise CPR instead.

Safeopedia Explains Automated External Defibrillator (AED)

AEDs are becoming increasingly more common in public areas, more specifically public sporting areas. CPR combined with the use of an AED can increase the likelihood of survival of a cardiac arrest by 75% or greater. AEDs are effective and efficient because the automated feature means that they can be used by anyone, as the instructions are dictated by the device. Therefore, specific training is not required for use. Though training is not necessary, AED training is now being incorporated into standard first aid and CPR certification courses.
