What does AED stand for in aviation terminology?

In aviation terminology, AED stands for Automated External Defibrillator. This device is critical for providing immediate treatment to individuals experiencing sudden cardiac arrest on board an aircraft. The AED analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help restore a normal heartbeat.

The use of an AED is essential in emergency situations as it can significantly increase the chances of survival by providing timely defibrillation before professional medical assistance arrives. Flight attendants are trained to use AEDs as part of their emergency response protocols, ensuring they can act quickly and effectively in managing medical emergencies during flights.

The other options represent terms that may sound plausible in the context of emergency equipment, but they do not accurately reflect the standard definition of AED in the aviation and medical communities.
