On the afternoon of July 16th, dispatch received a radio call from the park’s remote north entrance station reporting a female bicyclist who was experiencing chest pain. VUA Chris Reinhardt went to the 52-year-old woman’s aid and relayed patient information to responding rangers and other park emergency services personnel. While other resources were still en route to the scene, Reinhardt advised that the woman had become unresponsive and that he was beginning CPR. EMS personnel, including park medic Jason Ramsdell, arrived to find the woman in cardiac arrest. They immediately employed an AED to administer three shocks to her. The shocks, combined with ALS medications, restored her breathing. She was then flown by Mercy Air to a hospital in Medford. The combination of effective early CPR, delivery of the first shock from an AED within eight minutes of the arrest, and ALS interventions contributed to saving the woman’s life. Responding to the incident were rangers, personnel from fire management, fee collection and resource management, and the Chemult Rural Fire Protection District ambulance. Supervisory park ranger Jan Lemons was the incident commander.
