Identifying AED errors | Wellbeing
AEDs (Automated External Defibrillators) and defibrillators are increasingly found in public spaces due to their life-saving potential. When used promptly, they can increase a cardiac arrest victim’s chance of survival by up to 74%.
However, recognizing errors or malfunctions in AEDs and defibrillators is essential. Regular inspection and timely maintenance ensure the device is ready when emergencies arise. But have you learned how to identify common issues with an AED or defibrillator?
Let’s explore some of the most frequent errors with Wellbeing so you can be prepared when every second counts.
- Failing to Recognize Device Error Alerts
Most AEDs and defibrillators on the market are equipped with a self-test function to automatically detect errors and signal when there’s a malfunction. However, many devices display alerts that go unnoticed or unaddressed in time.
Examples:
- ZOLL AED Plus typically shows an error through a red X icon at the top right corner of the device.
- Heart+ResQ™ NT-180 indicates a fault using a red button located in the top right corner.
Always ensure staff or users are familiar with these indicators and check the device regularly.
- Failing to Regularly Check Battery and Electrode Pad Expiry Dates
Each AED model has its own lifespan for batteries and electrode pads. Regularly inspecting and replacing these components on time ensures the device will function properly during an emergency. Using expired components may cause the device to fail at a critical moment.
- Storing the Device in Improper Conditions
Each AED has specific requirements regarding humidity, dust, exposure to light, water resistance, and pressure tolerance. Storing the device in unsuitable environments can lead to deterioration or malfunction.
If you notice signs like mold, cracks, or discoloration, immediately assess the device and its storage conditions to prevent failure when needed most.
- Incorrect Installation or Accessory Setup
Many AEDs or defibrillators become unusable during emergencies simply because they were installed or assembled incorrectly—often without the user realizing it.
Always follow the manufacturer’s instructions carefully when setting up the device and ensure it shows a successful activation signal (without performing a test shock). A quick check can prevent serious consequences during real emergencies.
