An AED is a portable medical device used to help people experiencing sudden cardiac arrest. It analyzes the heart's rhythm and, if necessary, delivers an electric shock to help the heart re-establish an effective rhythm. AEDs are designed to be easy to use, even for people without medical training, and are commonly found in public places like schools, airports, and offices.
