What does a flashing green light on the AED signify?

A flashing green light on an Automated External Defibrillator (AED) signifies that the device is operational. This indication shows that the AED has completed its self-check and is ready for use in an emergency situation. When the AED is operational, it assures the user that the device is functioning correctly and is equipped to provide the necessary assistance during a cardiac emergency.

A flashing green light is crucial for users, as it serves as a visual confirmation that they can confidently rely on the AED to deliver shocks if needed. This operational status is essential because in an emergency, having a fully functional and ready-to-use AED can make a significant difference in outcomes.

In contrast, other indicators such as a steady red light or specific warnings would be associated with low battery levels, lack of power, or a device in standby mode. These would signal the need for further action, such as recharging the device or ensuring it is powered on, but the flashing green light confirms that everything is in order for immediate use.
