Sudden cardiac arrest can happen anywhere: at work, at home, in a public place. When it does, every second matters. An AED (Automated External Defibrillator) can make the difference between life and death, and the good news is: you don’t have to be a medical professional to use one.
In this blog, we’re breaking down how AEDs work, when to use them, and why they’re essential in every workplace.
What Is an AED?
An AED is a portable device that delivers an electric shock to help restart a heart that’s stopped beating effectively. It’s designed for quick, easy use in emergencies, even by someone with no medical background.
You’ll find AEDs in many public spaces: airports, gyms, schools, shopping centres, and increasingly, workplaces. That’s because early defibrillation, combined with CPR, greatly improves survival chances after cardiac arrest.
When Should You Use an AED?
Use an AED if someone:
- Collapses suddenly
- Is unresponsive
- Is not breathing normally or not breathing at all
Always call emergency services (999 or 112) first. Once help is on the way, grab the AED and begin the steps below.
How to Use an AED (Step-by-Step)
- Turn on the AED – Most units power up automatically when opened or have a clearly marked power button. The device will start giving voice instructions.
- Expose and dry the chest – Remove any clothing and wipe the chest dry if needed.
- Attach the electrode pads – Follow the diagrams on the pads (one goes on the upper right chest, the other on the lower left side).
- Let the AED analyse the heart rhythm – Make sure no one is touching the person during analysis.
- Press the shock button if advised – Only deliver a shock if the AED tells you to. Don’t worry, it won’t let you shock someone who doesn’t need it.
- Resume CPR if prompted – Continue CPR as instructed until emergency services arrive or the person shows signs of life.
Common AED Myths – Debunked
“I might hurt them if I use it wrong.”
AEDs are built with safety in mind. They won’t deliver a shock unless it’s necessary.
“AEDs are only for trained professionals.”
False. AEDs are meant to be used by the public. The device guides you through each step with clear audio and visual instructions.
Why Every Workplace/Public Space Should Have an AED
- Time matters – For each minute without defibrillation, survival chances drop by 7–10%.
- They’re easy to use – AEDs are designed for real people in real emergencies.
- It’s part of a safer work environment – Having an AED on site can save lives and shows your commitment to health and safety.
