Tech. Sgt. Cole Anderson begins a vital signs test on iStan, the patient simulator, Oct. 5, 2014, at the Pittsburgh International Airport Air Reserve Station. For an aeromedical evacuation technician such as Anderson, iStan serves as an important training tool to practice inflight patient care. This patient simulator can produce sweat from sweat-like glands, “bleed” from certain parts of the body, and even get a swollen tongue. (U.S. Air Force photo by Senior Airman Justyne Obeldobel)
