Automatic External Defibulator
A device designed so that a layman can use it to resuscitate a heart attack victim
I guess they might be called something else in other countries.
In the US you will find them mounted in malls, airports, other places of gathering.
An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient, and is able to treat them through defibrillation, the application of electrical
therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.
With simple audio and visual commands, AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level cardiopulmonary resuscitation (CPR) classes
