An automated external defibrillator (AED) is a potentially life-saving device that can help save the life of someone experiencing sudden cardiac arrest. However, in order for an AED to work effectively, it needs to be properly maintained and kept in good condition. In this article, we’ll discuss how to maintain an AED and keep it in good condition.

#1. Conduct Regular Inspections

It’s important to inspect the AED regularly to ensure that it is in good working condition. Check the battery status and expiration date, and ensure that the electrode pads are properly attached and have not expired. Also, check that the AED’s software is up to date and that any diagnostic tests are performed successfully.

#2. Store the AED Properly

Store the AED in a location that is easily accessible, well-lit, and dry. It’s important to ensure that the AED is not exposed to extreme temperatures, humidity, or direct sunlight. Also, make sure that the AED is not stored near any strong electromagnetic fields or devices.

#3. Keep the AED Clean

Keeping the AED clean is essential to maintaining its functionality. It’s important to use a clean, dry cloth to wipe down the AED and its accessories on a regular basis. However, make sure not to use any harsh chemicals or cleaning agents, which can damage the device. Follow the cleaning instructions provided by the manufacturer.

#4. Replace Parts When Necessary

Replace any parts of the AED when they are damaged or have expired. This can include the electrode pads, batteries, and any other accessories that may need replacing. Always use parts that are compatible with the AED and have been approved by the manufacturer.

#5. Train Employees

Make sure that all employees who may need to use the AED are properly trained on how to use it. They should know how to recognize the signs of cardiac arrest, how to properly attach the electrode pads, and how to operate the AED. By ensuring that all employees are properly trained, you can increase the chances of a successful rescue.

#6. Keep Records

It’s important to keep detailed records of all AED inspections, repairs, and maintenance. Keep a logbook that includes the date, time, and results of each inspection, and any repairs or replacements made. This will help ensure that the AED is always in good condition and ready to use in an emergency.


An AED is a potentially life-saving device, but it needs to be properly maintained and kept in good condition to work effectively. By conducting regular inspections, storing the AED properly, keeping it clean, replacing parts when necessary, training employees, and keeping detailed records, you can ensure that the AED is always in good condition and ready to use in an emergency. Remember, the life you save could be that of someone you love.
