What must be done if an AED indicates a low battery?

When an Automated External Defibrillator (AED) indicates a low battery, the appropriate action is to change the battery. AEDs are critical pieces of medical equipment used in emergencies to deliver electric shocks to restore a normal heart rhythm in individuals experiencing sudden cardiac arrest. A low battery can compromise the device's ability to function effectively when needed.

Changing the battery ensures that the AED is fully operational and ready for immediate use in an emergency situation, thereby enhancing the safety of passengers and crew. Regular maintenance checks, including battery status checks, are essential to ensure the AED's reliability.

In contrast, simply keeping the AED for emergencies without addressing the low battery status could result in a failure to respond adequately in a critical situation. While reporting the situation to the captain and replacing the AED may be considered, the most direct and immediate action is to replace the depleted battery, ensuring the device remains fully functional.
