Wyoming AED requirements at a glance
Here is what Wyoming law asks of an AED program, row by row, with the statute behind each answer.
| Requirement | Required? | What the law says |
|---|---|---|
| Inspect and maintain AEDs | Yes | Everyone who possesses an AED must make sure it is maintained and tested per the manufacturer's guidelines (§ 35-26-102(a)(ii)). The site's immunity also depends on meeting this duty (§ 35-26-103(b)). |
| Train expected users | Yes | Everyone who possesses an AED must complete CPR and AED training from the AHA, Red Cross or another nationally or Department of Health recognized course, with a refresher every two years. The duty falls on the possessor, not on expected users. It is also a condition of the site's immunity (§§ 35-26-102(a)(i), 35-26-103(b)). |
| Notify agencies of AEDs | Yes | Through AED placement reporting: see that row. |
| Register the program | No | Not in state law. |
| Report AED locations | Yes | Anyone who possesses an AED must tell the local 911 center and ambulance service that it has one, where it is, and what type it is (§ 35-26-102(b)). This is also a condition of the site's immunity (§ 35-26-103(b)). |
| Physician medical direction | No | Not required. The law protects a prescribing physician who authorizes an AED purchase but does not require physician oversight (§ 35-26-103(a)). |
| Report each AED use | Yes | Each time an AED is used on a patient, the use must be reported to the licensed physician. The law does not say which physician or who must report (§ 35-26-103(c)). |
| Written plan or records | No | Not in state law. |
| Call 911 when an AED is used | No | Not in state law. |
| School cardiac emergency plan | No | No school plan rule. HB 115 (2026), which would have required district cardiac emergency response plans, was not considered by the full House and died. |
| Other requirements | No | Not in state law. |
| AEDs required at specific sites | No | Not in state law. |

Is medical direction required in Wyoming?
No. Wyoming law doesn’t require a physician to oversee an AED program.
Not required. The law protects a prescribing physician who authorizes an AED purchase but does not require physician oversight (§ 35-26-103(a))
Some programs choose a medical director anyway, for example to write the response protocol or review each use. If you want one, AED Log’s Medical Direction add-on is $65 per AED per year.
Training requirements
Yes. Wyoming law requires CPR and AED training for the people expected to use an AED.
Everyone who possesses an AED must complete CPR and AED training from the AHA, Red Cross or another nationally or Department of Health recognized course, with a refresher every two years. The duty falls on the possessor, not on expected users. It is also a condition of the site's immunity (§§ 35-26-102(a)(i), 35-26-103(b))
Training still matters: an AED talks the rescuer through each step, but people who have practiced start CPR sooner and hesitate less. Keep each responder’s card current, since most CPR and AED cards last two years. See how long CPR and AED certification lasts.
Inspection and maintenance
Yes. Wyoming law requires AED owners to keep each AED maintained and tested.
Everyone who possesses an AED must make sure it is maintained and tested per the manufacturer's guidelines (§ 35-26-102(a)(ii)). The site's immunity also depends on meeting this duty (§ 35-26-103(b))
In practice, that means check the status indicator, the pads’ and battery’s expiration dates and the cabinet on a regular schedule, replace anything used or expired, and keep a dated record of each check. Our AED inspection requirements guide covers the routine, and the free AED inspection checklist is a printable version.
EMS notification, registration and placement reporting
Yes. Wyoming requires AED owners to tell EMS, or another agency the law names, that they have an AED and where it is.
Placement reporting: Anyone who possesses an AED must tell the local 911 center and ambulance service that it has one, where it is, and what type it is (§ 35-26-102(b)). This is also a condition of the site's immunity (§ 35-26-103(b)).
Keep the confirmation with your program records, and update it when an AED moves or is replaced. AED Log’s document library keeps registrations, letters and notices with the AEDs they cover.
Notification after an AED is used
Yes. Wyoming requires each AED use to be reported.
Reporting the use: Each time an AED is used on a patient, the use must be reported to the licensed physician. The law does not say which physician or who must report (§ 35-26-103(c)).
After any use, replace the pads, check the AED and its rescue kit, and write down what happened while it’s fresh. AED Log’s incident reports record whether a shock was advised, how many were delivered, whether CPR was given and when EMS arrived.
AEDs required at specific locations in Wyoming
No. Wyoming law doesn’t require AEDs at any particular kind of site.
That doesn’t make an AED optional everywhere: insurers, landlords, accreditors and other rules can still ask for one, and an AED is the only treatment that can restart a heart in cardiac arrest.
Does Wyoming's Good Samaritan law protect AED users?
Yes, with conditions. Wyoming protects people who use an AED in good faith, but some of that protection depends on the AED program meeting the law’s duties.
What the Wyoming (WY) Good Samaritan law covers: A physician or any other person who gives emergency care in good faith without being paid at the place of an emergency, accident or mental health crisis can’t be held liable for civil damages for good-faith acts or omissions. The subsection states no gross negligence exception; unpaid volunteer ambulance crews are covered separately.
AED-specific protection: Anyone who uses or tries to use an AED in a perceived emergency is immune unless the harm came from willful, criminal, reckless or grossly negligent conduct, and no training is needed. The person responsible for the AED's site is immune only if it met the possession duties: training, maintenance and EMS notice.
