In an emergency, time is of the essence, and if someone’s heart stops, an Automated External Defibrillator (AED) can be the difference between life and death. These devices are designed to deliver a shock to the heart, jump-starting its rhythm during sudden cardiac arrest (SCA). But what happens when you grab an AED and discover it’s not working? It’s a scenario no one wants to face, but it’s crucial to be prepared just in case.
At Rescue One Training for Life, we emphasize the importance of preparedness, and that includes knowing how to handle situations when things don’t go as planned. Let’s break down what you should do if you find yourself in this kind of predicament and how proper maintenance can prevent it from happening in the first place.
What Should You Do When Your AED is Dead?
Step 1: Stay Calm and Assess the Situation
When dealing with a sudden cardiac arrest, emotions run high, but keeping a level head is vital. If you reach for your AED and it’s not working, it’s easy to panic. However, time is critical, so instead of losing those precious moments, focus on what you can control.
Step 2: Call 911 Immediately
Even if an AED is available, the first step in any emergency involving sudden cardiac arrest is to call 911. Emergency medical professionals are trained to handle these situations and will arrive with advanced life-saving equipment. When you call, be sure to provide specific details about your location and the nature of the emergency so they can respond as quickly as possible.
Step 3: Start CPR
While AEDs can deliver a life-saving shock, CPR (Cardiopulmonary Resuscitation) is another critical action. If your AED isn’t working, you must immediately begin CPR to keep blood and oxygen circulating throughout the body. Effective chest compressions can sustain a person’s life until professional help arrives. Rescue breaths are helpful too, but if you’re not trained, simply focus on chest compressions—fast and deep, at a rate of about 100-120 compressions per minute (think of the beat of “Stayin’ Alive” by the Bee Gees).
CPR keeps oxygen flowing to vital organs, especially the brain, and every minute without CPR or defibrillation decreases the chance of survival by 10%.
Step 4: Look for Backup AEDs
Often, more than one AED is available in many locations such as schools, gyms, airports, or corporate buildings. If your primary AED is dead or malfunctioning, ask someone nearby to find a backup unit. Time is still of the essence, but checking another location for a working AED could save a life.
The Importance of AED Maintenance
Now that we’ve discussed what to do in an emergency when your AED isn’t functioning let’s focus on how to avoid being in that situation in the first place. An AED is only effective if it’s ready to use, so proper maintenance and planning is essential.
Regular Checks are Non-Negotiable
AEDs are incredibly reliable, but they’re not invincible. They have a few parts that require routine checks and replacements, such as batteries and electrode pads, which can expire over time. Each AED is designed to perform self-checks periodically, but this doesn’t mean you should rely solely on the device to catch every issue. The following checks should be part of your routine:
- Battery Life
AED batteries don’t last forever. Most have a shelf life of 2 to 5 years, but that can vary depending on the manufacturer. Make it a habit to check the battery status regularly. Many AEDs have an indicator light or screen that will tell you whether the battery is low. If you see a low battery or error signal, replace the battery immediately. - Electrode Pads
Just like batteries, the electrode pads attached to AEDs can expire. If the pads are expired, they may not adhere properly, or worse, the shock may not be delivered effectively. Most pads have an expiration date printed on them, so checking these periodically and replacing them as needed is necessary. - Device Function
Many AEDs have a self-test function that regularly checks the device’s status. However, a visual check should be part of your maintenance routine. If the indicator light is flashing red, the AED needs attention. If it’s green, you should be in the clear—but still, do the manual checks regularly for peace of mind.
When Preparedness Saved a Life
To emphasize the importance of maintaining your AED properly, let’s look at a real-world example.
Consider the case of a high school gym in Maryland. During a basketball game, one of the players suddenly collapsed on the court. The coach, who had received CPR and AED training, quickly recognized the signs of sudden cardiac arrest. The school’s AED was immediately retrieved, but to their dismay, the battery was dead. Panic set in for a moment, but thanks to their preparedness, the staff had a backup AED in another part of the building.
While one team member called 911, another ran to grab the backup AED. Meanwhile, the coach began performing CPR on the student. Within minutes, the backup AED was brought to the scene, and a shock was delivered, restoring the player’s heart rhythm.
The student survived, and doctors later confirmed that quick access to a working AED was instrumental in saving his life. However, it’s also important to note that the facility had backup systems in place, including another AED and a coach trained in CPR.
This story highlights two key takeaways:
- AED maintenance is crucial. The initial panic could have been avoided if the first AED had been properly maintained.
- Backups and training matter. When things don’t go as planned, having a backup AED and people trained in CPR makes all the difference.

Why Maintaining an AED Can Save a Life
The statistics show sudden cardiac arrest is a leading cause of death, with over 350,000 incidents occurring annually outside of hospitals in the U.S. alone. For every minute that passes without defibrillation, a victim’s chances of survival decrease by about 10%. This means that every second counts and your AED must be ready to go at a moment’s notice.
Maintaining your AED properly ensures:
- Reliability – An AED that’s regularly checked and maintained is less likely to malfunction in an emergency.
- Peace of Mind – Knowing your AED is ready means you can focus on saving lives rather than worrying about equipment failure.
- Compliance – Some areas have legal requirements for maintaining AEDs, especially in public places like schools, gyms, and offices. Failing to properly maintain an AED can result in fines and, more importantly, lost lives.
Don’t Let a Dead AED Cost a Life
An AED is a powerful life-saving tool only if properly maintained and functioning. Having an AED maintenance plan, ensuring time is taken to regularly check all your AED devices, replacing batteries, and training your team can make all the difference when seconds count.
If your AED is dead during an emergency, you still have options—CPR, calling 911, and looking for a backup can buy time until help arrives. However, to avoid this scenario, regular maintenance is key.
