Creates a single national baseline of civil‑liability protection for people who use automated external defibrillators (AEDs), owners of AEDs, and owners or managers of places where AEDs are used during perceived medical emergencies. It aims to reduce fear of lawsuits so more AEDs are installed and used to save lives from sudden cardiac arrest.

Provides immunity from civil lawsuits for good‑faith responders, premises owners/lessees/managers, and AED owners, while keeping accountability for intentional or reckless misconduct and for AED owners who fail to properly maintain a device. It also defines key terms to make the protections clear and consistent nationwide.
