So many lives have been saved because of the automated external defibrillator. This device can diagnose automatically a potential cardiac episode like ventricular tachycardia or arrhythmia. It is responsible for re-establishing the rhythm of the heart. One of its most vital components is the AED pads. Different sets of pads are used for children and adults.

AED pads are made of thin flexible conductor inside a protective polymer backing. This is held by hydrogel adhesive. Good pads should be durable enough to stand the rigors of CPR and harsh conditions. Typically, they are soft, oval shaped and flexible. The lead wire connector is often times designed for fast and easy insertion.
