Maryland is the first state to offer a statewide lifesaving trauma response initiative that carries whole blood aboard state police helicopters. When a Maryland State Police medevac helicopter responds to a scene, emergency teams might only have seconds to provide lifesaving aid to an injured person. Through a new partnership called “Blood on Board,” involving state police, Shock Trauma, the Maryland Institute for Emergency Medical Services Systems and the University of Maryland Medical Center, the helicopters will carry whole blood for emergency transfusions.
