Let's talk statistics for a moment... it's a long read, but worthwhile.
356,000+
Out-of-hospital cardiac arrests occur in the U.S. each year
The CDC uses this annual estimate to describe cardiac arrests that happen outside a hospital.
10.5%

This share is from 2024 U.S. adult out-of-hospital cardiac arrest data; nursing homes accounted for another 11.1%.
7% to 10%
Estimated drop in survival probability for each minute of delay
The FDA describes defibrillation as time-sensitive for a person who remains in a life-threatening arrhythmia.
Preparedness is more than a purchase.
A public-access AED needs a known location, current pads and battery, and a simple inspection routine. The data on bystander CPR and AED use show why access and upkeep deserve attention alongside the device itself.
Placement has to fit the setting.
Most adult out-of-hospital cardiac arrests occur at home, while public locations account for a meaningful share. Workplaces, schools, gyms, and community spaces need a location plan that makes an AED easy to find when seconds matter.
National figures do not replace local planning.
Local requirements, building layout, population, and response plans vary. Use this page as a factual starting point, then confirm the practical details for the people and place you are protecting.
