What is an AED used for?

An Automated External Defibrillator (AED) is a portable medical device used to treat sudden cardiac arrest (SCA), a condition where the heart unexpectedly stops beating. The AED analyzes the heart's rhythm and, if necessary, delivers an electric shock to help restore a normal heartbeat. Here’s how it works:

1. Detection: When someone collapses and is unresponsive, an AED is quickly attached to the person's chest via adhesive pads. The device then analyzes the heart's rhythm to determine if a shock is needed.

2. Shock Delivery: If the AED detects a life-threatening arrhythmia, such as ventricular fibrillation or pulseless ventricular tachycardia, it instructs the user to deliver a shock. The shock can potentially restart the heart or restore a normal rhythm.

3. Guidance: AEDs are designed to be user-friendly and often provide audible and visual instructions to guide the rescuer through the process, including performing CPR if necessary.

AEDs are crucial in emergency situations because they can be used by both medical professionals and laypersons, significantly increasing the chances of survival for someone experiencing SCA when used promptly.
