What does AED stand for?

The term AED stands for Automatic External Defibrillator. This device is crucial in emergency situations where a person is experiencing sudden cardiac arrest. It is designed to be user-friendly and can be operated by individuals with minimal training. The AED analyzes the heart's rhythm and determines whether a shock is needed to restore a normal heartbeat. Its automation allows it to provide audio and visual prompts to guide the user through the process, making it accessible for laypersons as well as medical professionals. The importance of this device cannot be overstated, as it can significantly increase survival rates when used promptly.
