What does AED stand for?

The correct answer, AED, stands for Automated External Defibrillator. This device is essential in emergency medical situations as it is used to treat individuals experiencing sudden cardiac arrest. An AED works by analyzing the heart's rhythm and delivering an electric shock if necessary to restore a normal heartbeat.

Understanding what an AED is and how it functions is critical, especially in environments like airports and on planes where quick medical response can be vital. Training staff on the use of AEDs enhances safety and readiness to deal with cardiac emergencies effectively.

The other terms, while they may sound plausible, do not accurately represent the widely recognized medical device used in emergency situations. The focus on "automated" and "external" in the correct definition underscores its purpose and usability.
