An Automated External Defibrillator (AED) is a medical device designed to analyze heart rhythms and deliver an electrical shock if necessary to restore normal heart function during sudden cardiac arrest.

AEDs should be placed in easily accessible and visible locations with high foot traffic, such as public buildings, schools, workplaces, and sports facilities.

AEDs should be inspected weekly to ensure they are in proper working order and have fresh batteries. Regular maintenance, typically performed annually, should be conducted by trained technicians.

AEDs are designed to be used by anyone, regardless of medical training. They provide clear and concise instructions, enabling lay rescuers to assist individuals experiencing sudden cardiac arrest.
