Six of us attended a day course in how to give CPR and use an AED run by The Irish Heart Foundstion

An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation and pulseless ventricular tachycardia in a patient,[1] 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 layperson, and the use of AEDs is taught in many first aidcertified first responder, and basic life support(BLS) level cardiopulmonary resuscitation (CPR) classes.[2]

The portable version of the defibrillator was invented in the mid-1960s by Frank Pantridge in BelfastNorthern Ireland, a pioneer in emergency medical treatment.

Here in this video we have a person learning how to use an AED.

It was a great course and we all received a certificate.
