Colorado ties AED owner protection to a short list of program steps (C.R.S. § 13-21-108.1), and a 2025 law (SB25-191) simplified those steps while adding AED standards for schools.
Training:
People expected to use the AED must complete CPR and AED training in a course that meets nationally recognized standards. See our CPR and AED certification classes.
EMS Notification:
Owners must notify the local emergency communications or vehicle dispatch center of the AED's existence, location, and type. AED365 program management keeps location records current.
Written Plan and Maintenance:
Owners keep written plans covering AED placement, training, coordination with EMS, maintenance, and reporting of AED use, and must maintain and test the AED to the manufacturer's guidelines. Our pad and battery guide lists replacement intervals by model.
Medical Oversight:
Since SB25-191, written plans no longer need review or approval by a physician, and owners no longer keep a list of authorized users.
Use Protocol:
Anyone who uses an AED on a person in cardiac arrest must call EMS as soon as possible.
Good Samaritan Protection:
Colorado protects good-faith AED users from civil liability, along with physicians involved in an AED program, whoever arranges AED placement, CPR and AED trainers, and whoever is responsible for the site. This protection does not cover gross negligence or willful and wanton misconduct.
Schools:
Starting January 1, 2026, public schools that have AEDs must place and maintain them to nationally recognized standards, and nonpublic schools must meet the same standards. Browse AEDs for schools.
