3. Electrode Pad Inspection and Replacement

A core component of any effective AED maintenance checklist is the systematic inspection and timely replacement of electrode pads. These pads are the direct point of contact with the patient, and their ability to adhere properly and conduct electricity is non-negotiable for successful defibrillation. Because the adhesive and conductive gel on the pads degrade over time, they have a strict expiration date that must be respected to ensure the AED can deliver a life-saving shock.

This task involves more than just glancing at a date; it's about guaranteeing the pads are in pristine, rescue-ready condition. Dried-out gel, poor adhesion, or damaged packaging can all lead to therapy failure. Implementing a regular check ensures that the pads will function exactly as intended during the high-stress environment of a sudden cardiac arrest emergency.

Why Pad Management is Critical

Expired or compromised electrode pads are one of the most common and preventable causes of AED failure. If pads don't stick firmly to the patient's chest, the electrical current cannot be delivered effectively, rendering the rescue attempt futile. A proactive replacement strategy is absolutely essential.

• Guaranteed Conductivity: Ensures the gel is moist and can effectively transfer the electrical shock.
• Proper Adhesion: Verifies the adhesive is strong enough to maintain full contact with the skin, even on a sweaty or hairy chest.
• Prevents Device Errors: Using expired pads can cause the AED to issue a "Check Pads" error, delaying or preventing a shock.

Effective pad management is a simple but powerful way to ensure your equipment is always ready. For a deeper understanding of the different types of pads and their specific requirements, exploring key factors for effective use can provide crucial insights into making the right choices for your AED program. Taking the time to manage these consumables is a small investment that pays massive dividends in a crisis.

The video above demonstrates the straightforward process of checking and replacing AED pads, a skill every program manager should be familiar with. Consistent checks and strict adherence to expiration dates remove a significant point of potential failure from your emergency response plan.

4. Self-Test Function Execution and Documentation

While daily visual checks are fundamental, diving deeper into the device's own health reporting is a critical part of a comprehensive AED maintenance checklist. Modern AEDs are sophisticated medical devices equipped with internal self-test functions that automatically verify their core systems. This automated process is your AED’s way of giving itself a regular check-up, ensuring the internal circuits, software, and shock delivery systems are all functioning as designed.

These self-tests are the backbone of device reliability, running on schedules set by the manufacturer—which can be daily, weekly, or monthly. Understanding and properly documenting these tests bridges the gap between a visual "all clear" and true operational certainty. It confirms that the device isn't just present but is internally prepared to deliver that life-saving shock.

Why Self-Test Verification is Essential

Relying solely on a green status light without understanding the self-tests behind it is a gamble. Verifying and documenting these tests provides concrete evidence of the device's health over time. It allows you to track patterns, identify potential recurring issues, and maintain a defensible record of due diligence, which is vital for compliance and liability purposes.

• Proactive Fault Detection: Identifies internal electronic issues that are invisible to the naked eye before they can lead to failure during a rescue.
• Compliance and Record-Keeping: Creates an auditable trail demonstrating that the device has been maintained according to manufacturer specifications and industry best practices.
• Informed Maintenance: Provides detailed diagnostic data that can help technicians or manufacturer support quickly resolve any problems that arise.

Beyond simply performing self-tests, meticulously documenting their execution and outcomes is paramount, and leveraging effective business process documentation templates can significantly streamline this critical aspect of AED readiness. Different AED models provide this data in various ways; for instance, LIFEPAK devices perform daily self-tests with results stored internally, while some HeartStart units conduct weekly tests and display results directly on their status indicators. Other brands, like Defibtech, offer detailed reports that can be downloaded via specialized software.
