Automated External Defibrillators (AEDs) save lives—plain and simple. But like any tool, AEDs need to be used correctly to be effective. While these devices are designed to be user-friendly, it’s still easy to make mistakes, especially in a high-stress situation. The good news is that most of these errors are easily avoidable with a little knowledge and preparation.
Let’s walk through some of the most common AED mistakes people make and how to avoid them.
1. Not Having an AED Ready or Available
One of the biggest mistakes is not having an AED available when it’s needed. It sounds obvious, but a surprising number of places—gyms, schools, offices—don’t have an AED on-site. Even worse, sometimes the AED is tucked away in a cabinet or a hard-to-reach area, making it difficult to access quickly.
How to avoid it:
Make sure an AED is available and easy to access. Place it in high-traffic, visible areas, and regularly remind employees, coaches, or staff where it’s located. The quicker you can get to an AED, the better the chances of saving a life.
2. Forgetting to Check the Battery and Pads
It’s easy to assume that an AED is always ready to go, but like any electronic device, it needs maintenance. AED batteries can die, and electrode pads have expiration dates. The last thing you want is to grab an AED during an emergency, only to find that the battery is dead or the pads are unusable.
How to avoid it:
Make AED maintenance part of your routine. Many AEDs come with maintenance programs or reminders. Check the battery regularly, replace it as needed, and make sure the pads are within their expiration date. It’s worth setting a reminder on your phone or calendar so you don’t forget!
3. Panicking or Hesitating to Use the AED
When someone collapses, it’s natural to feel panicked. However, one of the most common mistakes is hesitating to use the AED. People worry that they might use it incorrectly or cause more harm than good. The reality is that AEDs are built to be simple and intuitive—you won’t cause harm by using one, even if you're not an expert.
How to avoid it:
Trust the AED and yourself. The device will guide you through the process with clear, step-by-step instructions. It won't deliver a shock unless it's absolutely necessary. If you’re unsure, just start following the prompts—it’s better to take action than to wait.
4. Not Following the AED's Voice Instructions
Another mistake is failing to follow the AED’s voice prompts. Some people get distracted or think they know what to do without listening to the device. AEDs are designed to guide you with voice instructions, so following them is crucial for success.
How to avoid it:
Stay calm and focus on the AED’s instructions. The device is literally telling you what to do—just follow along, step by step. It’s there to help you, so let it do its job.
5. Not Pausing CPR When Instructed
Many people don’t realize that you need to pause CPR while the AED analyzes the heart rhythm. Continuing chest compressions during this time can interfere with the AED’s ability to determine whether a shock is needed. It’s one of the most common mistakes but easily preventable.
How to avoid it:
When the AED tells you to stop CPR, stop. This allows the device to analyze the heart rhythm without interference. Once the analysis is complete, the AED will tell you if a shock is needed or when to resume CPR.
6. Improper Pad Placement
In a hurry, it’s easy to place the AED pads incorrectly. Pads should be placed according to the diagrams on the AED unit, but in a high-pressure moment, people sometimes put them in the wrong spots.
How to avoid it:
Take a second to look at the diagram. AED pads are clearly marked, showing exactly where they need to go on the victim’s chest. Slowing down for just a moment can make all the difference in getting it right.
7. Not Preparing the Chest
An AED requires a clean, dry surface to work properly. Sometimes, people forget to remove clothing, wipe off sweat, or deal with chest hair, all of which can interfere with the AED’s ability to deliver a shock.
How to avoid it:
Make sure the chest is prepared before applying the pads. Remove any clothing, quickly wipe away sweat, and if necessary, use the razor in the AED kit to shave any chest hair that might interfere with pad placement.
8. Relying Too Much on the AED
While AEDs are powerful tools, they’re just one part of the equation. It’s crucial to also perform CPR until help arrives, as AEDs alone may not be enough to keep the heart pumping.
How to avoid it:
Remember, using an AED doesn’t replace the need for CPR. Keep performing chest compressions and follow the AED’s instructions until medical professionals take over.
Conclusion
In moments of crisis, the best thing you can do is stay calm and trust the AED. These machines are designed to be used by anyone, even those without medical training. By avoiding these common mistakes and making sure your AED is always ready, you can make a real difference when it matters most. After all, an AED is only effective if it's used correctly, and with a little preparation, you can be ready to save a life.
