Automated Electronic Defibrillator (AED): Must-Know Facts

Automated Electronic Defibrillators, or AEDs, are crucial for treating sudden cardiac arrest (SCA). When the heart abruptly stops, SCA happens, and it’s a top killer in adults.

In this article, we’ll explore all key facts on AEDs. We’ll cover what they are, their mechanism, their use, and their advantages. Additionally, we’ll bust some widespread misconceptions surrounding them.

What is an Automated Electronic Defibrillator (AED)?

An Automated Electronic Defibrillator (AED) is a compact life-saving gadget for treating sudden cardiac arrest (SCA), a top killer in adults. Simple to operate, even if you’re not medically trained, AEDs notably boost SCA survival odds.

These devices function by sending a regulated electric jolt to the heart, aimed at restoring its regular beat. They come with audio and visual cues, making the process user-friendly.


There are two key kinds of AEDs: fully automatic and semi-automatic. The fully automatic ones assess heart activity and administer a shock if needed, while the semi-automatic ones need you to hit a button for the shock.

A variety of brands and models are out there. Popular names include Philips, Zoll, and Cardiac Science.

Courses and Certification

You can find AED training courses through a range of providers like the Red Cross, American Heart Association, or even your local community college and fire department. Joining the CPR AED training will teach you to handle a patient in cardiac arrest and use an AED effectively.

These classes usually run for 2-4 hours and address topics like:

  • How does it work?
  • When to use it.’
  • How to use it?
  • AED safety

Once you finish, you’ll get a completion certificate. This certification generally lasts for two years.

Importance of AEDs in Sudden Cardiac Arrest

Sudden cardiac arrest (SCA) abruptly halts the heart’s beating and is one of the top killers among adults. The scary part? It can strike anyone, anytime.

AEDs are literal lifesavers for treating SCA. These gadgets send a measured electrical shock to the heart, aiming to get it back in rhythm. What’s more, you don’t need a medical degree to use one.

Time is of the essence with SCA. For every tick of the clock without defibrillation, survival odds dip by 10%. AEDs can turn the tide by acting fast, dramatically improving those odds.

Indeed, having an AED around can hike up SCA survival rates by a solid 50%. That’s why their presence is crucial in public spaces—think schools, offices, and malls.

How to Use an AED

Before you even think about using an AED, you’ve got some boxes to tick for safety:

  • Assess the situation: If the victim is in a risky spot, like a busy street, move them somewhere safer before whipping out the AED.
  • Watch for water: Please make sure the victim and the surface they’re on are dry. AEDs can shock through water, but it’s best to minimize that risk.
  • Pacemaker alert: If the victim has one, keep the AED pads away from it. Position them an inch below and slightly to the right.
  • Hands off during the shock: Seriously, please don’t touch the person while the AED is doing its thing.

Step-by-Step Guide

Here’s your step-by-step playbook for using an AED:

  • Power up the AED.
  • Listen closely to the voice instructions from the AED.
  • Place the pads correctly on the victim’s chest. One goes just below the right collarbone, and the other goes under the left armpit.
  • Step back and hit the shock button.
  • If no shock is advised, keep the CPR going.
  • If a shock’s on the menu, deliver it.
  • Stick with CPR till more help shows up.

What to Do After Using an AED

Once you’ve operated the AED, it’s crucial to remain beside the individual until medical help gets there. Keep an eye on their respiratory rate and heartbeat. If they aren’t breathing, it’s CPR time.

Here’s your to-do list afterward:

  • Stick close to the individual: Don’t go wandering off.
  • Track their breathing and pulse: If they stop breathing, jump into CPR mode. Should they be living, please take note of their pulse at two-minute intervals.
  • Revive via CPR when needed: If there’s no breath or pulse, fire up CPR again. Please keep it going until either professional help steps in or the individual takes a breath independently.

AED vs CPR: What’s the Difference?

Sudden cardiac arrest (SCA) instantly halts the heart’s function, posing a significant threat to adult lives. It’s a situation where every second counts and both AEDs and CPR can be lifesavers.

CPR, short for cardiopulmonary resuscitation, is a first aid method used to keep the blood and oxygen circulating to crucial organs. It involves a combo of chest compressions and rescue breaths.

Main Differences

AEDs use a regulated electric shock to reset the heart’s rhythm. In contrast, CPR manually pumps the heart and ventilates the lungs, sustaining blood and oxygen flow. AEDs are most effective in the initial moments following SCA, while CPR is your go-to until an AED or professional help arrives.

Survival Stats

Surviving SCA is tough, but using CPR or an AED quickly ups those odds.

  • Without either, the American Heart Association states a bleak 10% survival rate.
  • With CPR, survival rates climb to around 38%
  • Using an AED can boost survival chances to about 50%.

Combining AED and CPR

If you find someone collapsed and pulseless, immediately call 911 and start CPR. If there’s an AED close by, grab it and use it ASAP.

If you’re using an AED, the device will guide you when to halt CPR for a shock. When two people are on hand, one can administer the AED while the other continues CPR. Here’s a quick guide on combining the two:

  • Call 911 and initiate CPR.
  • If an AED is within reach, use it right away.
  • Listen to the AED’s voice prompts.
  • If no shock is advised, keep up the CPR.
  • When a shock is advised, go ahead and shock.
  • Stick with CPR until more help gets there.

Legal and Regulatory Aspects

The U.S. Food and Drug Administration (FDA) classifies AEDs as Class II medical devices. This signifies that before these devices hit the U.S. market, they need to pass specific safety and effectiveness standards.

Furthermore, the FDA mandates AED makers to offer usage training. Luckily, this training often comes free or at a minimal charge from the device manufacturers, distributors, and other associated entities.

Public Access

These days, spotting an AED in common areas like schools or malls is no rare sight. In fact, several state and local laws are pushing for AED installations in various public zones.

Where do you find one? Here’s a handy list:

  • Schools
  • Workplaces
  • Malls
  • Transport hubs like airports and train stations
  • Athletic arenas
  • Hotels and casinos
  • Gyms
  • Recreational spots
  • Government offices
  • Worship centers

And if you’re tech-savvy, a quick online search or mobile app can point you to the nearest AED in an instant!

AED Myths and Misconceptions

Myth: AEDs are only for medical pros.

Fact: Nope, AEDs are user-friendly and intended for the general public. You don’t need a medical degree to use one. They offer voice-guided steps and on-screen cues to walk you through the procedure.

Myth: AEDs might shock folks who aren’t experiencing a heart crisis.

Fact: Rest easy. AEDs have built-in safeguards to stop accidental shocks. They first analyze the heart activity of the victim. If cardiac arrest isn’t the issue, the device won’t fire a shock.

Myth: Operating an AED is complex.

Fact: Quite the opposite! AEDs are designed to be straightforward. You’ll get step-by-step voice and visual guidance. Plus, their built-in safety measures make them foolproof to use.
