How often should I check my AED?
Keep Your AED Ready
The Vital Importance of Checking Battery and Pad Expiry Dates
In a cardiac emergency, seconds count. Automated External Defibrillators (AEDs) are designed to deliver life-saving shocks to individuals experiencing sudden cardiac arrest. But owning an AED isn’t enough—it must be properly maintained to ensure it works when needed. A critical part of this maintenance is regularly checking the battery and pad expiry dates. Neglecting these simple checks could lead to device failure in an emergency.
Why Regular AED Maintenance Matters
An AED relies on both its battery and electrode pads to function effectively. If either component is outdated, damaged, or depleted, the device may fail to deliver the necessary shock, reducing the chances of survival for the person in distress. Routine maintenance ensures that your AED remains ready for action at all times.
Understanding AED Batteries and Pad Expiry
AED batteries have a limited lifespan, generally lasting anywhere between two to five years, depending on the model. The electrode pads, which adhere to the patient’s skin and conduct the shock, usually expire within 18 to 30 months after manufacture. Expired pads may lose their adhesive quality or the gel may dry out, reducing their effectiveness in an emergency. Similarly, an old battery might not have enough power to administer a shock properly. Most devices will have a battery indicator to warn owners when the battery is underperforming. Battery life will be impacted if the device needs to be used on a casualty.
How to Check AED Battery and Pad Expiry Dates
Making sure your AED is fully functional is easy with regular checks. Here’s a simple step-by-step guide:
- Check Expiry Labels – Batteries and electrode pads have clear expiration dates printed on their packaging. Make a habit of inspecting them frequently.
- Monitor the AED’s Status Indicator – some AEDs perform regular self-tests and will display a warning if there’s an issue with the battery or pads.
- Physically Inspect Components – Check for any visible signs of wear, damage, or leaks in the battery and pads.
- Keep a Maintenance Log – Record expiry dates and set reminders for replacements well in advance.
- Replace Components After Use – If your AED has been used in an emergency, the pads must be replaced immediately, and the battery may need inspection.
The Consequences of Neglect
An AED that isn’t properly maintained can pose serious risks. If a cardiac emergency occurs and the device fails due to an expired battery or faulty pads, valuable time is lost in seeking alternative treatment. In life-or-death situations, having a fully functional AED can mean the difference between survival and tragedy.
Best Practices for AED Maintenance
Ensure your AED remains in peak condition with these simple practices:
- Store It in an Accessible Location – Place the AED in a visible, easily accessible area where anyone can grab it quickly during an emergency.
- Follow Manufacturer Recommendations – Each AED model has specific maintenance guidelines. Always refer to the user manual for best practices.
- Dispose of Expired Items Safely – Old batteries should be recycled at designated collection points, while used pads should be disposed of properly, especially if they’ve been contaminated.
- Conduct Routine Checks – Set a schedule for inspecting and replacing AED components to ensure they are always ready for use.
Conclusion
AEDs are invaluable tools in saving lives, but they must be maintained to ensure they function in an emergency. Regularly checking the battery and pad expiry dates is an essential step in keeping your device operational and effective. By implementing routine maintenance, setting up reminders, and following best practices, you can ensure that your AED is always ready when needed.
