An automated external defibrillator (AED) is a portable device used to restore normal heart rhythm to patients in cardiac arrest by delivering an electrical shock to a patient thought the chest wall.
A built-in computer checks a victim's heart rhythm through adhesive electrodes. The MCU calculates whether defibrillation is needed, and a recorded voice indicates whether to press the shock button on the AED.
This shock momentarily stuns the heart and stops all activity giving the heart an opportunity to resume beating effectively.
The charge is generated by high-voltage generation circuits from energy stored in a capacitor bank in the control box.
