There’s something quietly reassuring about seeing a defibrillator in your local high street, school, or village hall. It signals preparedness, that if the worst happens, help is close at hand. But that peace of mind can give a false sense of security if the defibrillator isn’t actually ready to use.
A device that’s been forgotten, left unchecked, or hidden behind a jammed cabinet door can become a false promise. That’s why maintenance matters just as much as installation. In this blog, we’ll break down the simple steps that keep defibrillators in working order, explain the risks of neglect, and explore how smart technology can make maintenance that much easier.
The importance of defibrillator readiness
Sudden cardiac arrest can happen anywhere — at a bus stop, in a park, outside a school. When it does happen, public access defibrillators (AEDs) give bystanders a powerful tool to restart a person’s heart before emergency services arrive. Sadly, a defibrillator that doesn’t work is worse than not having one at all. At least if there’s no device, people will call for help immediately. A faulty defibrillator, on the other hand, wastes precious minutes at a time when every second counts.
Ensuring your AED is always ‘rescue ready’ goes way beyond good practice. It’s a moral responsibility. These devices are placed in public spaces to save lives. If they’re not maintained properly, they simply can’t do that.
Common defibrillator maintenance issues
Like any piece of equipment, defibrillators and their cabinets are vulnerable to wear and tear, especially when exposed to outdoor conditions. Here are some of the most common maintenance issues:
Battery failures
AED batteries degrade over time, particularly in extreme temperatures. A drained battery is one of the most common reasons for defibrillator failure.
Pad degradation
The electrode pads, which deliver the life-saving shock, can dry out or degrade if exposed to moisture or simply over time. Using expired pads could render the AED ineffective.
Cabinet malfunctions
Outdoor defibrillator cabinets, especially in coastal areas, can suffer from rust or jammed locks due to salty air or lack of maintenance. A locked or stuck cabinet door can delay access when time is tight.
Smarter maintenance with remote monitoring
Technology is making defibrillator maintenance easier than ever. At Turtle Engineering, we offer GPS-enabled systems that allow for remote monitoring.
With these smart cabinets, you can:
- Get notified when a defibrillator is removed or moved.
- Receive alerts if the cabinet door is opened or left ajar.
- Track battery and pad status remotely, so you know when replacements are needed.
- Monitor environmental conditions that might affect the cabinet or device.
These solutions mean fewer manual checks and faster responses when something’s wrong. For communities with limited time or resources, it’s a huge help.
One village defib guardian shared how remote monitoring has saved them countless hours. Before, they had to drive across town to manually inspect each unit. Now, they get real-time alerts and can act only when needed. It’s peace of mind and it saves time, ensuring that their defibs are always ready for a cardiac arrest.
Hopefully time saving technology such as cabinet monitoring and defib tracking will encourage councils and other organisations to install even more public access defibs in locations previously neglected.
Simple defibrillator maintenance steps to start today
You don’t need to overhaul your entire system to make a difference. Start small and build habits that keep your defibrillators in top condition:
Create a maintenance schedule
Mark monthly (defib) and 6 monthly (cabinet) check-ins on a calendar or set reminders on your phone.
Assign a custodian
Choose someone responsible and train them on what to look for. Defibs should be registered on The Circuit (national database) with a named Guardian.
Use technology to help
Consider installing a remote monitoring system, especially if your device is outdoors or in a remote area.
