Medical emergencies happen every day. Knowledge is everything when faced with a medical emergency. Emergency situations that affect heart health are often navigated thanks to devices known as AEDs. Knowledge of AEDs and recognition of why they’re such vital components of medical emergency response protocols can save lives.

What are AEDs?

The American Heart Association notes an automated external defibrillator (AED) is a lightweight and portable device that delivers an electric shock to the heart through the chest when the device detects an abnormal rhythm. 

What Calls for the use of an AED?

The AHA notes AEDs help people who experience sudden cardiac arrest, which is often deadly if not treated immediately. Sports fans may recall an incident in January 2023 that played out on national television during Monday Night Football. In that situation, Buffalo Bills safety Damar Hamlin went into cardiac arrest on the field after making a tackle against the Cincinnati Bengals. Those in the stadium and millions more watching at home looked on in fear and uncertainty as Hamlin laid on the field for 10 minutes. It was later revealed that an AED was utilized to restore Hamlin’s heartbeat on the field before he was taken away by an ambulance. The instance involving Hamlin, who has since fully recovered and returned to play for the Bills, underscores the significance of AED training and the benefits of having a readily accessible AED.

Who can use an AED?

The AHA notes AEDs were designed to be used by the general public so anyone with access to the device can save a life when a person goes into cardiac arrest. 

Where can an AED be found?

Wider availability of AEDs remains a point of emphasis for many both within and outside the medical community. Educators and coaches remain among the most vocal advocates for AEDs within schools and in places where athletes routinely compete. The AHA recommends AEDs be placed near elevators, cafeterias, main reception areas, and on walls in well-trafficked corridors. Educating individuals, including young athletes, about the location of AEDs and how to use them can be a lifesaving preventive measure.

Is AED training available?

The AHA offers CPR and AED training to individuals within the United States, and information about such sessions can be found at heart.org/CPR. Individuals in Canada also can access such training by visiting the Canadian Red Cross at redcross.ca.

AEDs save lives, and anyone can learn to use these invaluable devices.
