User Guide & Resources for Automated External Defibrillators (AEDs)

Automated External Defibrillators (AEDs) are becoming increasingly common and available in many public spaces. These devices are designed to analyze heart rhythms and provide visual and audio prompts to guide rescuers through emergency procedures in the event of cardiac arrest.

1. What is Cardiac Arrest?

Cardiac arrest (also known as circulatory arrest) is a condition where the heart stops beating or beats ineffectively (fibrillation). It is a critical emergency that can strike anyone—including healthy individuals with no prior medical history—at any time and in any place.

The most common cause is an abnormal heart rhythm, specifically Ventricular Fibrillation. This abnormality often occurs when the heart muscle is damaged due to a heart attack or when the heart is deprived of sufficient oxygen.

2. What is an AED? Step-by-Step User Guide

The Automated External Defibrillator (AED) is a device used to correct life-threatening heart rhythms by delivering a controlled electric shock. Designed to be remarkably user-friendly, this device allows even those with absolutely no medical experience or knowledge to significantly increase the survival chances of cardiac arrest victims, both in hospital settings and in the community.

Step 1: Power on the AED and remove the electrode pads from their sealed package. Remove or cut through the victim's clothing and wipe away any sweat from the chest to ensure good contact.
Step 2: Tear open the pad packaging, peel off the backing, and attach the pads to the victim's chest at the indicated positions. Place the first electrode pad on the upper right side, directly below the victim's collarbone.
Step 3: Place the second electrode pad on the left side, directly below the victim's armpit (as shown in the device's diagram). Ensure the pad is aligned vertically along the body's axis from head to toe.
Step 4: The AED will automatically begin analyzing the heart rhythm. Ensure that no one is touching the victim during this process. Strictly follow the visual and/or verbal instructions provided by the machine (e.g., "Shock Advised" or "Start CPR").
