What does the acronym AED stand for?

The acronym AED stands for Automated External Defibrillator. This device is a critical piece of equipment used in emergency situations to treat individuals experiencing sudden cardiac arrest. It analyzes the heart’s rhythm and, if necessary, delivers an electric shock to restore a normal heartbeat. AEDs are designed to be user-friendly, allowing even those without medical training to utilize them effectively in life-threatening situations.

Understanding the role of an AED is vital for lifeguards and other first responders, as quick access to an AED can significantly increase the chances of survival for a person experiencing cardiac issues. The specific terminology outlined in the correct answer emphasizes the device’s automated function and external application, distinguishing it from other medical devices that may not necessarily be designed for public use or immediate deployment in emergencies.
