An AED is only effective if it's properly maintained and ready to use at a moment's notice. Regular maintenance ensures your device will function flawlessly when needed most. This guide covers everything you need to know about AED maintenance, from daily checks to component replacement.

1Why AED Maintenance Matters

AEDs are sophisticated medical devices that require periodic attention. Failure to maintain your AED can result in device malfunction during an emergency, depleted batteries, expired electrode pads with reduced adhesion, and non-compliance with health authority requirements. A well-maintained AED can be the difference between life and death.

2Daily and Weekly Checks

Modern AEDs perform automatic self-tests, but you should still conduct visual inspections:

Daily Visual Inspection

Check the status indicator light (should be green, not red or amber); Verify the AED is in its designated location and accessible; Ensure the cabinet or case is closed and undamaged; Confirm AED signage is visible and intact.

Weekly Inspection

Open the AED case and check for any visible damage; Verify electrode pads are sealed and within expiration date; Check battery expiration date (typically printed on battery); Listen for any audible alarms from the device; Test the cabinet alarm if using a wall-mounted AED.

3Battery Maintenance and Replacement

AED batteries are the device's power source and have a limited lifespan:

Battery Lifespan

Most AED batteries last 4-7 years in standby mode (Philips HeartStart: 4-5 years, ZOLL AED Plus: 5 years, Defibtech Lifeline: 7-9 years). Battery life can be affected by extreme temperatures common in the GCC, particularly if stored in vehicles or outdoor cabinets.

When to Replace

Replace batteries before the expiration date, not after. If the status indicator shows low battery (often red or amber light), replace immediately. After using the AED in an emergency, install a fresh battery even if the device indicates remaining charge.

Replacement Process

Order manufacturer-approved replacement batteries (generic batteries may void warranty). Follow device-specific instructions in the user manual. After installation, verify the status indicator shows green (ready). Document the replacement date and new battery expiration.

4Electrode Pad Maintenance and Replacement

Electrode pads have a limited shelf life due to the conductive gel:

Pad Lifespan and Storage

Most pads expire 18-30 months from manufacture date. Heat and humidity in the GCC can accelerate degradation - store AEDs in climate-controlled environments when possible. Keep pads sealed in original packaging until use.

When to Replace Pads

Replace before the printed expiration date. After any use (even if AED did not deliver a shock), pads must be replaced - they are single-use only. If pad packaging is damaged or opened, replace immediately.

Pediatric Pads

If your facility serves children, maintain a set of pediatric pads (for children under 8 years or less than 25 kg). Check expiration dates separately from adult pads.

5Monthly Maintenance Checklist

Conduct a comprehensive monthly inspection: Verify all status indicators and self-test results; Check and document battery and pad expiration dates; Inspect electrode pad packages for integrity; Test rescue accessories (scissors, razor, gloves, CPR mask if included); Clean the exterior with a damp cloth (avoid harsh chemicals); Review and update your maintenance log.

6Annual Professional Inspection

Even with regular self-checks, schedule annual professional servicing: Have a certified technician or supplier inspect the device; Verify energy output and shock delivery (using test equipment, not on humans!); Update firmware if available; Replace any worn or damaged components; Ensure compliance with local health authority standards; Obtain certification of inspection for your records.

7Environmental Considerations in the GCC

The Gulf climate presents unique challenges: High temperatures can degrade batteries and pads faster; Store AEDs in air-conditioned spaces (ideal: 15-35°C); Outdoor AED cabinets should be temperature-controlled or insulated; Dust and sand can infiltrate cases - keep AEDs sealed when not in use; Humidity can affect electronics - use desiccant packs in storage cases if needed.

8Maintenance Record Keeping

Maintain a logbook for each AED documenting: Installation date and location; Serial number and model; Battery and pad expiration dates; Dates of all inspections, replacements, and servicing; Any incidents of use; Contact information for the responsible person. Many modern AEDs with Wi-Fi connectivity offer digital monitoring and automated alerts for maintenance needs.

9Where to Get Replacement Parts in the GCC

Purchase replacement batteries and pads from: Authorized AED distributors in UAE, KSA, Qatar, Oman; Manufacturer-certified suppliers (ensures genuine parts and warranty compliance); Medical equipment suppliers with proper licensing. Avoid third-party or counterfeit parts - they may not meet safety standards and can void your warranty.

Key Takeaways

Proper AED maintenance is simple but critical. By following a regular inspection schedule, replacing components before expiration, and keeping detailed records, you ensure your AED will be ready to save a life when needed. Assign a responsible person in your organization to oversee AED maintenance, and consider setting calendar reminders for inspections and component replacements. A well-maintained AED is a reliable AED.
