When it comes to life-saving equipment like Automated External Defibrillators (AEDs), it is important to ensure that they are in top condition. But how do you know when it’s time to replace an AED? A recent study reveals that outdated AEDs can significantly impact survival rates. AEDs that are more than 10 years old or have not been properly maintained can be up to 50% less effective in delivering life-saving shocks. This is a staggering statistic when you consider that early defibrillation can increase the chance of survival by up to 70% in cases of sudden cardiac arrest.
As technology advances, so do the capabilities of AEDs. This makes it essential to keep up with the latest models and features. Regularly assessing your AED’s condition and understanding the signs that indicate it needs replacement can make a life-or-death difference. In this blog, we’ll explore the key indicators that it’s time to upgrade your old AED.
How long does an AED last?
The lifespan of an Automated External Defibrillator (AED) typically ranges from 5 to 10 years. Several factors influence this duration:
- Battery Life: Most AEDs have batteries that last between 4 to 5 years. Some newer models may have batteries with longer lifespans.
- Electrode Pads: The pads or electrodes usually need replacement every 2 to 5 years, depending on the manufacturer’s recommendations.
- Maintenance: Regular maintenance and adherence to manufacturer guidelines can extend the AED’s effective lifespan.
- Technological Advances: Upgrading to newer models every 5 to 10 years ensures you benefit from the latest advancements in technology and features.
What are the indications that an AED is going to expire?
Recognizing when an AED is nearing the end of its useful life is crucial for maintaining readiness in emergencies. Here are some key indications that your AED may be approaching expiration:
- Battery Warning: Many AEDs have a battery life indicator or alarm that signals when the battery is low or nearing expiration.
- Expiration Date on Pads: Check the expiration date on the electrode pads, as they typically need replacement every 2 to 5 years.
- Self-Check Alerts: AEDs perform regular self-checks. If your device indicates a malfunction or fails a self-test, it may be time for replacement.
- Battery Replacement Warning: Some models have indicators that alert you when it’s time to replace the battery, usually based on a specific time interval.
- Manual Review: Periodically review the manufacturer’s guidelines for your AED model to ensure it is within its recommended operational life.
- Physical Condition: Inspect the AED for physical damage or wear, which could affect its performance and reliability.

How to maintain an AED?
Maintaining an Automated External Defibrillator (AED) is crucial to ensure it’s ready to use in an emergency. Here’s a simple guide to keeping your AED in top condition:
- Regular Inspections: Check the AED monthly to ensure it is in working order. Verify that the device’s indicators show it’s functioning correctly.
- Battery Checks: Monitor the battery life indicator. Replace the battery according to the manufacturer’s recommendations, typically every 4 to 5 years, or when the device alerts you.
- Electrode Pad Replacement: Replace the electrode pads based on their expiration date, usually every 2 to 5 years. Always keep a spare set of pads on hand.
- Clean the Device: Wipe down the AED with a soft, dry cloth to keep it free from dust and debris. Avoid using harsh chemicals or submerging the device in water.
- Keep Updated: Follow any manufacturer updates or recalls. Ensure you’re aware of any new instructions or changes to maintenance procedures.
- Perform Self-Tests: Most AEDs conduct self-tests to ensure proper functionality. Review these test results and address any issues immediately.
- Ensure Accessibility: Place the AED in a visible, accessible location. Regularly check that it’s not obstructed or misplaced.
What can happen when using a defective AED?
Using a defective AED can have serious consequences. It compromises both the device’s effectiveness and the patient’s safety. Here’s what can happen:
- Ineffective Shock Delivery: A defective AED may fail to deliver a shock or provide an inappropriate shock, reducing the chances of successfully resuscitating the patient.
- Inaccurate Diagnostics: The AED might misinterpret the patient’s heart rhythm, leading to incorrect instructions and potentially delaying necessary treatment.
- Device Failure: Critical components of the AED, such as the battery or electrode pads, might not function correctly, rendering the device useless in an emergency.
- Increased Risk of Injury: If the AED malfunctions and delivers an improper shock, it could potentially cause harm or further injury to the patient.
- Delayed Response: Issues with the AED can delay the response time, which is crucial in cardiac emergencies where every second counts.
- Legal and Financial Consequences: Using a defective AED can lead to legal ramifications if it results in patient harm, along with potential financial costs related to lawsuits and fines.
