AEM Status

The facility should establish the scheduled PM frequency through its maintenance policy because the manual directs the user to inspect the device frequently, as necessary, but does not assign a fixed external PM interval.

If the facility performs this PM at a different interval or changes the listed activities, the changes should be managed through the facility’s approved AEM program, risk assessment, maintenance history, and applicable regulatory requirements.

What This PM Procedure Covers

• External condition and cleanliness
• Readiness-status verification
• Electrode condition, connection, and expiration
• Battery age, condition, and expiration
• Manual self-test
• Audio, display, LED, and control checks
• Optional rhythm-analysis and shock-delivery testing
• Optional delivered-energy verification
• CPR-feedback verification
• Rescue-supply inventory
• Return-to-service decision

Required Tools and Equipment

• AED Plus Simulator/Tester or equivalent
• Defibrillator analyzer when delivered-energy accuracy is verified
• Compatible AED test cable or adapter
• Stopwatch or analyzer timing function, when needed
• Soft damp cloth
• Manufacturer-permitted cleaning solution
• Small flat-blade screwdriver for battery-compartment access, if batteries are replaced
• Replacement electrodes, batteries, and rescue supplies as needed

A simulator alone confirms functional shock delivery but does not verify delivered-energy accuracy. Use a defibrillator analyzer when energy accuracy is part of the facility PM procedure.
