What does an AED stand for?

An AED stands for Automated External Defibrillator. This device is crucial in providing life-saving assistance during cardiac arrest situations. When a person experiences sudden cardiac arrest, the normal rhythm of the heart is disrupted, and an AED can analyze the heart's rhythm and deliver a shock if necessary, in order to restore a normal rhythm. The "automated" aspect means that the device is designed to identify whether defibrillation is needed without requiring advanced training, making it accessible for use by laypersons and healthcare providers alike.

The terminology in the other choices does not reflect the established term used globally in emergency medical settings. This specificity in the name highlights the AED's role and function, distinguishing it from other devices or concepts that do not accurately describe this life-saving tool.
