The Automated External Defibrillator (AED) functions as a lifesaving device which provides electric shocks to treat sudden cardiac arrest (SCA) cases. The portable device provides easy operation which enhances survival chances during cardiac emergencies. The effectiveness of the most advanced Automated External Defibrillator depends solely on its preparedness state. Your defibrillator can become nonfunctional at a critical moment because of neglecting regular maintenance procedures. Regular maintenance of AEDs works in the same way as fire extinguishers and smoke alarms to ensure their functionality.
This guide explains AED maintenance significance through actionable steps and provides a comprehensive AED checklist to maintain device readiness.
Why AED Maintenance Matters
AEDs maintain reliability as designed but function as electronic devices whose components naturally deteriorate with time. AEDs that receive no maintenance will stop working properly thus causing fatal delays when emergencies occur. The most common issues include:
- Expired electrode pads
- Depleted batteries
- Damaged casings
- Outdated software
- Environmental damage (moisture, dust, heat)
The foundation of emergency preparedness rests on performing regular equipment maintenance. A regularly serviced AED ensures successful rescues while following workplace and school and public facility regulatory requirements.
Key AED Maintenance Tips
1. Conduct Regular Visual Inspections
Begin monthly inspections of the device by performing basic checks which should become a regular practice. A visual examination should be performed on the device to check for any noticeable signs of wear or damage by using a checklist.
- The status indicator shows a green color or it displays a warning message.
- The device casing shows no evidence of damage through cracks or dents or signs of moisture.
- The electrode pads must be sealed and should have dates that have not passed their expiration.
- The device battery displays an appropriate level according to specifications or indicates a warning.
- The AED storage container and its housing should be clean and easily accessible for use.
The LED or visual status indicator on numerous AEDs displays green when all systems are operating properly. If the indicator shows red or flashing lights, consult the user manual immediately.
2. Replace Expired Pads and Batteries
The lifetime of electrode pads and batteries as consumables ends before their expiration dates. AED batteries maintain their functionality between 2 to 5 years while electrode pads have a typical 2-to-4-year expiration period. When pads and batteries expire they make the AED device less reliable.
Develop a maintenance schedule that includes automatic alerts for changing parts. The production companies of AED devices offer mobile applications and alert systems which provide early warnings to users.
3. Ensure Accessibility and Visibility
Having a functional automated external defibrillator (AED) becomes useless when people cannot locate it during emergencies. Ensure your AED:
- The device remains accessible without any barriers in the way.
- The AED should be placed inside either a high-visibility wall-mounted box or a high-visibility cabinet.
- The facility maintains clear signs that direct users to the AED location with accompanying arrows.
- The facility maintains complete awareness of the AED location among all staff members and volunteers and students.
Organize short walkthroughs and awareness drills to teach people how to locate and quickly reach the AED.
4. Store in the Right Environment
The environmental factors significantly affect how defibrillators should be maintained. AEDs must be stored:
- In a dry, dust-free area
- Away from direct sunlight and heat sources
- The recommended storage temperature range for this device extends from 32°F to 122°F according to manufacturer specifications (0°C to 50°C).
Weatherproof and climate-controlled cases should be used to protect outdoor AED placements and extreme climate conditions. The improper storage of these devices will harm their sensitive components particularly the battery and pads.
5. Regular Self-testing & Manual Testing Procedures
Modern AEDs conduct automated self-checks through daily, weekly or monthly procedures based on their model type. The automated diagnostic system performs three functions to check internal circuitry and battery status and electrode pad connectivity.
However, it’s still important to:
- Check the status indicator by sight to confirm it matches the recorded information in the AED log.
- Follow any manual test procedures which your model requires.
- Follow the manufacturer’s manual to perform all testing procedures.
6. The Maintenance Log for AED
A maintenance log system is both a necessary requirement and a wise practice according to legal standards and compliance rules. The AED maintenance log should contain the following information:
- Date of each inspection
- Status and findings (pads, batteries, status light)
- The maintenance log should include all actions performed for replacement and cleaning and repair activities.
- The person who conducted the inspection needs to provide their name in the record.
The documentation of your AED maintenance through a detailed log serves as proof to demonstrate proper guideline-based maintenance in emergency situations or legal reviews.
Creating a Comprehensive AED Checklist
Your safety routine should include AED maintenance through standard checklist implementation. Here’s a sample:
Monthly AED Maintenance Checklist:
- The status indicator demonstrates the device functions correctly.
- The AED device remains clean while being free from dust and debris accumulation.
- The AED contains fresh electrode pads which remain sealed and have not reached their expiration date.
- The AED battery remains within its expiration period and displays a complete charge.
- The AED cabinet along with its signage remains easily visible to everyone.
- The AED remains available for immediate use without any barriers.
- The inspection details should be recorded in the log.
Annual Review Checklist:
- Replace both pads and battery immediately before their expiration date.
- Check for any available software and firmware updates that apply to the AED system.
- The staff receives periodic training refreshers about the AED.
- The team should evaluate how well patients and staff can see the placement and its signage.
- The organization needs to verify that all maintenance logs contain complete information.
Common AED Maintenance Mistakes
Avoid these frequent oversights:
- Ignoring expired pads or batteries.
- The self-check process should not replace visual examinations of the device.
- A locked storage space or obstructed area should not be used for AED storage.
- The failure to record inspections together with maintenance activities.
- The failure to provide updated training after performing a device upgrade constitutes a common mistake.
Preventive measures regarding device maintenance prove simpler and more beneficial than handling equipment breakdowns during critical situations.

FAQs
1 When performing AED device inspections what frequency should I follow?
AED inspections should be performed monthly but increased frequency is needed when there is heavy foot traffic or high exposure.
2 Which parts of an AED require periodic replacement?
Typically, batteries (every 2–5 years) and electrode pads (every 2-4 years). Check the maintenance instructions provided by your model specifically.
3 Do AEDs perform automatic self-checks?
Yes. Modern AEDs conduct automatic diagnostic tests either once per day or once per week. Visual inspections together with manual checks remain fundamental components of AED maintenance.
4 When an AED fails to operate during an emergency what will happen?
The consequences can be fatal. The importance of emergency preparedness depends on both regular AED maintenance and following an AED checklist.
5 Can AEDs be stored outside?
Yes, with weatherproof, heated storage cabinets. Manufacturers’ specified environmental requirements must always be met.
