AED Inspection & Readiness: A Facility Maintenance Guide
AED maintenance is mostly about readiness: the device is where it belongs, accessible, showing a normal ready status, and stocked with unexpired model-approved pads and battery.

What to check first
Bring these
- Flashlight
- Site AED program and inspection record
Before touching anything
- Use the AED manufacturer's inspection schedule and your facility's emergency-response/AED program.
- As a practical facility routine, a documented monthly readiness check is a useful baseline unless the manufacturer or site program requires more frequent checks.
- Also check after an AED has been used, after an alarm/error indication, and after any event that could have damaged the cabinet or device.
What to do
- 1Status indicatorConfirm the device displays the manufacturer's normal ready/OK status. A red, failed, blank or unfamiliar status indication requires follow-up using the device manual or service provider.
- 2Access and cabinetConfirm the AED is in its designated location, readily accessible, not blocked, and the cabinet/signage are intact. If the cabinet has an alarm, verify it according to the site's approved procedure without compromising AED readiness.
- 3Pads and batteryCheck that electrode-pad packages are sealed and within their expiration date, and that the battery status/expiration or replacement date is acceptable for the model. Confirm required pediatric pads/key, spare battery or other site-required accessories are present where applicable.
- 4Physical conditionLook for cracks, contamination, moisture, missing components, damaged cables/connectors or evidence of tampering. Do not dismantle the AED for a routine facility inspection.
- 5Rescue kit and signageVerify the site's intended rescue supplies are present and usable, such as gloves, scissors, razor and barrier mask, and that directional/AED signage remains visible.
- 6After the AED is usedDo not simply return it to the cabinet. Follow the manufacturer's post-use process and the facility's medical/emergency-response program. Typically this includes replacing used pads and other consumed supplies, checking/replacing the battery if required, cleaning the device as instructed, downloading/event-data handling only by authorized personnel, and confirming the AED returns to its normal ready status before it is placed back in service.
What to record
Record AED location/ID, date, ready-status indication, pad expiration, battery status/date, cabinet/access condition, accessory status, deficiencies and corrective action. Keep the record consistent with your facility's AED program and manufacturer recommendations.
