Automated External Defibrillators (AEDs) are lifesaving devices that provide an electric shock to the heart in the event of sudden cardiac arrest. Their presence in public spaces, workplaces, schools, and homes can mean the difference between life and death. However; just like any medical equipment, AEDs have a limited lifespan and knowing when to replace or service your AED is crucial for ensuring it remains effective in an emergency.
In this blog, we’ll guide you through the key signs that indicate it’s time to replace your AED, helping you stay prepared to save lives when it matters most.
1. End of AED Manufacturer Warranty
Every AED comes with a warranty period, which typically ranges from 5 to 8 years. Once this warranty expires, it’s important to carefully evaluate the condition of your AED.
While an expired warranty doesn’t mean the device will stop working immediately, it does signal that your AED is no longer supported by the manufacturer for repairs or servicing. Parts could also potentially become harder or more expensive to source as the device ages. Diagnosis and repair of an AED not under warranty can sometimes cost more than a brand new AED! If your AED is no longer under warranty, replacing it with a newer model is a proactive approach to ensure you have the latest technology and continued support.
2. Technological Advancements in Defibrillators
Like all medical technology, AEDs have continued to evolve over the years. Newer models come with enhanced features, such as clearer voice prompts, improved battery life, more advanced shock delivery systems, and compatibility with remote monitoring systems.
If your AED is several years old, it may be lacking some of these features, which could be crucial in an emergency situation. While your older AED might still work, investing in a new model with the latest advancements could improve the chances of successful defibrillation, especially in high-stress environments.
3. Frequent Error Messages or Malfunctions
If your AED starts displaying error messages or malfunctions frequently, it’s a sign that the device may need to be replaced. Common errors that come up during routine AED self-tests are battery capacity, electrode sensors, software and internal circuitry issues, and shock capacitor test failures.
While most AEDs can be serviced to repair minor issues, persistent or serious malfunctions often mean it’s time for a replacement. If the device is older and out of warranty, the cost of repairs can sometimes exceed the cost of a new unit.
4. FDA Recalls and Manufacturer’s “End of Life” Status
Another critical aspect to consider when evaluating whether it’s time to replace your AED is whether the device has been subject to an FDA recall or has reached its “end of life” status with the manufacturer.
- FDA Recalls: The U.S. Food and Drug Administration (FDA) issues recalls for medical devices, including AEDs, if they are found to be faulty or pose a safety risk. If your AED has been recalled, it is essential to follow the manufacturer’s instructions and either return the device or replace it. Regularly check the FDA website for any updates on recalls and ensure that your AED is not part of a recall list. It is essential to monitor this as using a recalled AED could lead to a failure to deliver the necessary shock in an emergency.
- End of Life (EOL) Status: Many AED manufacturers eventually phase out older models. When a device reaches its end of life (EOL) with the manufacturer, it means the company will no longer support it with updates, parts, or servicing. If your AED is no longer supported or serviced by the manufacturer, it’s time to consider replacing it. Continuing to use an outdated device can leave you with a non-functional AED if something goes wrong or if parts break. Always verify whether your AED is still supported by the manufacturer and, if not, replace it with a newer model.
5. Published Guidelines for Specific AED Ages
Several healthcare organizations provide guidelines regarding the replacement of AEDs based on the device’s age. While the specifics can vary depending on the model and manufacturer, here are some general recommendations:
- The American Hospital Association suggests that AEDs should be replaced or serviced at least every 7 to 10 years, depending on the model, usage, and maintenance. It’s important to check whether your device is up to date with the latest clinical guidelines, as AED technology and protocols may have evolved.
- Manufacturer-Specific Guidelines: Different AED manufacturers may have specific recommendations regarding the age at which their devices should be replaced. Some models may be considered obsolete after 7 years, while others may last longer with regular maintenance. Always consult the manufacturer’s guidelines for the recommended replacement or upgrade timeline for your specific AED model.
6. Lack of Regular AED Maintenance and Periodic Testing
One of the most critical aspects of ensuring your AED remains in optimal working condition is regular maintenance and testing. AEDs are designed to be user-friendly and reliable, but they still require consistent care to ensure they are functional when an emergency occurs.
- Periodic Testing: Most AEDs perform a self-test daily or weekly to ensure their components (such as battery, shock delivery system, and software) are working correctly. However, it’s crucial that you, as the owner or operator, periodically test the device manually. This includes checking the device’s status lights, confirming that it’s passing its self-test (if applicable), and ensuring it is ready for use.
Critical to testing: It is also important to ensure that the AED is capable of making appropriate shock/no-shock decisions. This means that the device’s algorithm should accurately analyze the heart rhythm and decide whether a shock is needed or not. In addition, the AED must be able to actually deliver the treatment when necessary. Even if the device indicates a “no shock advised” message, it’s essential to confirm that it can properly assess and deliver a shock if required.
- Maintenance Checks: Regularly inspect the device for any signs of physical damage, dust, or debris. Review the manufacturer’s maintenance schedule and follow it carefully. If the AED is not functioning correctly during a self-test or if any damage is found, it’s time to address the issue before it becomes a critical failure.
Neglecting regular maintenance or failing to test the device periodically can result in missed signs of a malfunction, making it essential to keep a close eye on your AED’s condition.
7. Environmental Factors and Wear and Tear on your AED
AEDs in high-use areas or exposed to extreme temperatures, humidity, or dust might wear down faster. Even if your device hasn’t reached its expiration date, if it shows signs of physical wear, such as cracks, corrosion, or internal damage, it may need to be replaced.
For AEDs stored in vehicles or exposed to harsh environments, always check for any external damage regularly and make sure it’s still functional. In cases where the device has sustained significant wear, it may be more cost-effective to replace it than to attempt costly repairs.
Conclusion: Stay Prepared, Stay Safe
Replacing your AED at the right time can save lives. By following these guidelines and staying proactive about the condition of your device, you can ensure that your AED is always ready for use when an emergency strikes. Regularly test the condition of your AED, maintain the device according to the manufacturer’s instructions, and invest in upgrades as needed to stay up to date with the latest technology and regulations.
Additionally, it’s crucial to stay vigilant for recalls or “end of life” notifications from the manufacturer, as well as any updates to clinical guidelines. An AED that isn’t functioning properly—or one that’s no longer supported by the manufacturer—will not be able to perform when it’s needed most.
Now, let’s take a moment to consider something we all experience in the workplace or at home: the frequency with which we replace common office equipment. How often do we upgrade or replace our laptops, desktops, cell phones, or other electronics? Many of us, whether due to performance issues, software updates, or simple desire for the latest technology, replace these devices every few years.
It’s not uncommon to see employees switching out laptops or desktops every 3 to 5 years, and many people upgrade their cell phones every 2 to 3 years to stay on top of new features and functionality. However, when it comes to AEDs, it’s easy to forget that they too have a limited lifespan.
How many of us still use a 10-year-old cell phone or rely on an outdated laptop in our personal or professional lives? Most of us wouldn’t dream of holding onto such old technology. Yet, when it comes to life-saving equipment like AEDs, many individuals and organizations fail to recognize the need for regular upgrades. Just as we wouldn’t hesitate to replace outdated phones or computers, we should treat AEDs with the same level of urgency and ensure they are up-to-date, functional, and ready to save lives.
Don’t wait until it’s too late, take the necessary steps today to ensure that your AED is fully operational and ready to save a life when every second counts.
