What does a green tab indicate on the AED?

A green tab on an automated external defibrillator (AED) signifies that the pads are present and functional. This visual indication is crucial for ensuring that the device is ready for use in an emergency situation. The presence of functional pads means that they are properly connected to the device, have not expired, and are ready to deliver the necessary shocks to a patient experiencing a cardiac arrest.

This feature is designed to provide a quick and clear status check for responders, allowing them to assess the AED's readiness at a glance without needing to open the device or conduct a lengthy inspection. This helps save valuable time during critical situations where every second counts.

In contrast, other indicators—like a red tab or an audible alert—would typically signal issues such as low battery, need for maintenance, or that the device is not operational. Thus, the green tab's specific indication reinforces the readiness and functionality of the AED pads, ensuring effective response during emergencies.
