What does AED stand for?

AED stands for Automated External Defibrillator. This device is crucial for providing immediate care during cardiac emergencies, specifically in cases of sudden cardiac arrest. The AED is designed to analyze the heart's rhythm and, if necessary, deliver an electric shock to restore a normal heart rhythm. Its automated nature allows even non-medical professionals to use it with minimal training, making it an essential tool in public places where the risk of cardiac events may be increased.

The other options do not accurately describe this life-saving device, which may lead to confusion regarding its function and importance in emergency situations. Understanding the correct terminology is vital for anyone involved in life-saving efforts, especially lifeguards and first responders.
