An Automated External Defibrillator (AED) is one of the most critical tools in saving lives during sudden cardiac arrest. Yet in an emergency, many bystanders hesitate—unsure when or how to use it. The truth is, using an AED quickly can mean the difference between life and death. Here’s what you need to know.
When Should You Use an AED?
You should use an AED any time a person collapses and is unresponsive with no normal breathing or pulse. It’s designed to analyze the heart’s rhythm and deliver a shock only if needed. It won’t shock a person unless it detects a shockable rhythm—so it’s incredibly safe.
Signs You Should Grab the AED:
- The person is unconscious
- Not breathing normally (gasping or not at all)
- No detectable pulse
- CPR has already been started
How Quickly Should It Be Used?
Every minute without defibrillation decreases survival chances by 7–10%. The sooner you apply an AED, the better the chance of restarting the heart in a survivable rhythm.
What Happens If You Don’t Use an AED?
If an AED isn’t used in time:
- The chance of survival plummets with every passing minute.
- CPR alone might not restart the heart—it can only buy time.
- The patient may suffer permanent brain damage after just 4–6 minutes without oxygen.
- Delaying AED use increases the risk of death.
What If You’re Afraid to Use It?
It’s common to hesitate, especially if you’ve never been trained. But AEDs are built to guide you through the process step-by-step—with voice prompts, visual cues, and safety checks. You can’t accidentally harm someone by using it. The real harm is not using it at all.
Final Thought: Take Action, Save a Life
AEDs are lifesaving, simple to use, and essential in cardiac emergencies. Whether you’re a healthcare worker or a bystander, your action—or inaction—matters. Use the AED, follow the prompts, and give someone the best chance at survival.
