A 2007 publication estimated that in the United States, 753 helicopters (and 150 dedicated fixed-wing aircraft) were in EMS service, providing about 3% of all ambulance transports.1 By 2011, the Association of Air Medical Services (AAMS) placed the number of rotor-wing (ie, helicopter) transport vehicles at about 900. Individual helicopter EMS (HEMS) programs' mission profiles and crew configurations vary widely. Varying programs have varying mission breakdowns (as well as differing aircraft and crew configurations), but a typical US HEMS program performs 54% interfacility transports, 33% scene runs, and 13% “other” mission types (eg, neonatal, pediatric, transplant related).2
