Elsewhere, the novel approach to pre-hospital care was also evolving. Portland's Leonard Rose, M.D., in cooperation with Buck Ambulance Service, instituted a cardiac training program and began training other paramedics. Baltimore's R. Adams Cowley, the father of trauma medicine, devised the concept of integrated emergency care, designing the first civilian Medevac helicopter program and campaigning for a statewide EMS system. Other communities that were early participants in the development of paramedicine included Jacksonville, Florida, Pittsburgh, Pennsylvania (in an expanded program), and Seattle, Washington (in an expanded program). In 1972 the first civilian emergency medical helicopter transport service, Flight for Life opened in Denver, Colorado. Emergency medical helicopters were soon put into service elsewhere in the United States. It is now routine to have paramedic and nurse-staffed EMS helicopters in most major metropolitan areas. The vast majority of these aeromedical services are utilized for critical care air transport (inter-hospital) in addition to emergency medical services (pre-hospital).
