How can you identify whether the AEDs are operational or non-operational?

The identification of whether an Automated External Defibrillator (AED) is operational or non-operational primarily relies on the status indicator lights. These lights provide a clear and immediate visual indication of the device's operational state. When the AED is functional, the status light will typically show a steady or green indicator, signifying that the device is ready for use. If there are issues, such as low battery or malfunction, the indicator might display a different color or blink, alerting the user to the problem.

While sounds made by the AED, visual inspection of components, and manual testing might provide additional insights into the device's operational state, the status indicator lights are specifically designed to give users the most straightforward and reliable assessment of readiness. This feature is critical in emergency situations where time is of the essence, allowing responders to quickly ascertain whether the unit can be used effectively.
