To comply with the state protocol for dispatching Medevac helicopters, an emergency responder at the scene of an incident must contact SYSCOM Helicopter Communications in Maryland where a Maryland state police officer is stationed. The officer makes the decision on dispatching Medevac services.
Weather conditions play an important role in the decision to launch a helicopter. Maryland state police Aviation Command requires visibility of three miles and a cloud height of 800 feet in the daytime and 100 feet at night to dispatch a helicopter.
In order to dispatch Medevac services, emergency medical services must make SYSCOM Helicopter Communications aware of the amount of injured patients and the type of trauma involved. A decision about which hospital to take patients to is made regarding the facility that specializes in treating a specific type of trauma.
