AED

What medical device does AED stand for?

Automated external defibrillator

An "AED" is a portable medical device used to help someone experiencing sudden cardiac arrest. The device analyzes the person's heart rhythm and, if needed, delivers an electrical shock to help restore a more normal heartbeat. The devices are designed to guide users through the process with clear voice and visual instructions.

AEDs are commonly placed in public spaces, such as airports, gyms, schools, and workplaces, so they can be used quickly during emergencies. They are designed for use by both trained responders and bystanders, and many models provide step-by-step prompts to help users respond safely while waiting for emergency services.
