Automatic external defibrillator

Automatic external defibrillator: Automatic external defibrillator (AED) is an electronic device which can give electrical countershock to revive a person in cardiac arrest. When the electrode patches of the device are applied to the chest and the device switched on, it detects the heart rhythm and gives audio prompts for action. If it is a shockable rhythm, it advises a shock and delivers one if activated. Otherwise it will advise the continuation of cardiopulmonary resuscitation (CPR).
