An Automated External Defibrillator (AED) is a life-saving device designed to help those experiencing sudden cardiac arrest (SCA). It’s portable, easy to use, and designed to be used by anyone, even those without medical training. AEDs work by delivering an electric shock to the heart to restore a normal rhythm, significantly increasing the chances of survival when administered promptly.
How Does an AED Work?
When a person experiences SCA, their heart’s electrical activity becomes chaotic, and it stops pumping blood effectively. This is where an AED comes in. The device analyzes the heart’s rhythm and determines whether a shock is needed. If necessary, it instructs the user to deliver a shock. AEDs are equipped with voice prompts, lights, and text to guide the user through the process, making it straightforward and manageable in high-stress situations.
How to Use an AED
1. Call 911 and turn on the AED: Most AEDs turn on automatically when opened; if not, press the power button.
2. Attach the Pads: Place the AED pads on the victim’s bare chest as shown in the instructions (one pad on the upper right side and the other on the lower left).
3. Analyze the Heart Rhythm: The AED will automatically analyze the heart’s rhythm. Ensure no one is touching the victim during this time.
4. Deliver the Shock (if needed): If the AED determines that a shock is needed, it will prompt you to press the shock button. Make sure everyone is clear of the person before delivering the shock.
5. Resume CPR: After the shock is delivered, or if no shock is needed, continue with CPR until emergency services arrive or the person shows signs of life.
