What does the acronym AED stand for?

The acronym AED stands for Automated External Defibrillator. This device is lifesaving and is used in emergency situations to treat individuals experiencing sudden cardiac arrest. It works by analyzing the heart's rhythm and determining whether a shock is necessary to restore a normal heart rhythm. The term "automated" indicates that the device is designed to guide the user through the process, making it accessible for use by laypersons or first responders who may not have advanced medical training. The inclusion of "external" specifies that the device is applied externally to the patient's chest, distinguishing it from internal defibrillators which are implanted in patients with specific heart conditions. This clear definition helps in recognizing the importance and functionality of the AED in emergency medical situations.
