about AEDs

An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses the 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 layperson, and the use of AEDs is taught in many first aid, certified first responder, and basic life support (BLS) level cardiopulmonary resuscitation (CPR) classes. Philips Automated External Defibrillators (AED) are the most widely used AED in the world.

If an AED is hooked up to a patient in the first 4-6 minutes, they have about a 92% chance of being resuscitated every minute there after they lose about 10% chance of being resuscitated every minute, 10 minutes after SCA(sudden cardiac event) with no AED, they have about less then 5% chance of being resuscitated.
