What should all crew members be informed of when an AED has been used?

When an AED (Automated External Defibrillator) has been used on a passenger, it's critical for all crew members to be informed to notify paramedics coming onboard. This is essential because paramedics need to know that an AED has been employed, as it provides them with vital information about the condition of the patient and the treatment that has already been administered. This can help them assess the situation swiftly and continue with appropriate care without delay.

Informing paramedics allows them to be better prepared for the medical care they will need to provide upon boarding the aircraft. Understanding the patient's status, such as whether a shock was delivered and any changes that might have occurred, is crucial for effective emergency response.

While halting all services, offering counseling, or preparing emergency exits may seem relevant in a broader emergency response context, the priority when an AED is used is to ensure that medical professionals are promptly informed so they can take over care efficiently.
