AED Basic Care and Maintenance

Adult Audience Only

 

SUMMARY

An automated external defibrillator (AED) is a small, portable medical device that generates a shock that can jolt the heart into beating correctly. To ensure AEDs function properly when needed, regular inspections are required.

 

GENERAL INFORMATION

If you are tasked with maintaining an AED, follow the manufacturer’s instructions on how and when to inspect the unit and replace batteries, pads, and electrodes. This information can be generally found in the operator’s instruction manual and/ or online and should be carefully followed. Be aware that laws governing the use and care of AEDs vary by state and often change, so become familiar with your state/local AED regulations. It is highly suggested that you add these devices to your monthly check of emergency equipment — just like for fire extinguishers and other safety devices — so they will be ready for an emergency.

In addition to regularly checking the AED manually, most brands of AED units perform multiple self-tests periodically. This will vary by brand and model. Many models will emit an alarm if there is an issue found during a self-test. However, you should never rely solely on an AED’s self-test. Manual inspections with documentation should occur monthly or as often as the manufacturer/state laws require. Batteries must remain in the AED for self-testing and manual testing to occur. Otherwise, the AED might not function during an emergency.

The designated person(s) maintaining an AED should check that the batteries and pads are intact and have not reached the expiration date. Order replacements well in advance of any expiration date. Some AED batteries have an “Install By” date instead of an expiration date. Know when batteries need replacement and be sure to document that information. Keep in mind that environmental conditions (e.g., heat, humidity) might affect the AED, batteries, and pads/electrodes. Check the manufacturer’s recommendations on proper AED storage.

It’s rare, but recalls of AEDs and their components do occur. Make sure to register your AED and components to receive recall notices.

After any AED use, the pads must be replaced. AED pads are single use. Check with the AED manufacturer and battery supplier for recommendations on battery replacement. There might be companies in your area that service AEDs for a fee.

To ensure readiness for use in the case of a sudden cardiac arrest, understand how to care for and maintain your AED, and ensure AED inspections are done regularly.
