Identifying Common AED Errors and Maintenance Issues | Wellbeing

1. Failure to Recognize Status Indicators

Most AED models on the market feature a "Self-test" function that automatically checks for errors and displays a specific status signal. However, many devices report errors that go unnoticed and unresolved by the owner.

• Example: The ZOLL AED Plus typically indicates an error with a Red "X" (or a specific indicator) in the status window on the front of the unit.

• Example: The Heart+ResQ™ NT-180 signals an error via a blinking Red light on the top right corner of the machine.

2. Neglecting Battery and Pad Expiration Dates

Every AED model has specific expiration dates for its battery and electrode pads (consumables). Regularly checking and replacing these components in a timely manner is essential to ensure the device remains fully operational and effective during emergency situations.

3. Improper Storage Environment

Each device has specific manufacturer ratings regarding humidity, dust, light exposure, water resistance, and crush resistance. Consequently, many AEDs malfunction due to improper storage conditions. If you detect signs such as mold, cracks, or discoloration on the casing, you must immediately inspect the quality of the storage environment and the device itself.

4. Incorrect Installation or Setup

There are numerous cases where an AED fails to function in an emergency because the accessories were installed incorrectly or the setup was not finalized, yet these errors went undetected. Therefore, always install the AED and its accessories strictly according to the manufacturer's instructions. Verify that the device signals a "Ready" status upon activation.

• Crucial Note: Never perform an actual electric shock (discharge) to test the device.
