# AED (Automated External Defibrillator)

An Automated External Defibrillator (AED) is a portable device used to administer an electric shock to the heart through the chest wall. The device is used in cases of sudden cardiac arrest, where the heart has stopped beating effectively. AEDs are designed to be easy to use with visual and voice prompts to guide the user through the process.
