Once in a while there are air evacuation operations which exist just for the purpose of transporting patients in need wherever they need to be picked up and taken. As you may not know , fixed wing air ambulance fleets occasionally have to be used simply because these case patients can not go by public airline service . That usually is because these are people who need a flight paramedic and/or medical care. Often there are men or women who are in need of medical aid when they fly. Those people that seek the services of non emergency air ambulance crews cannot go on the common air charter services . That usually is because these people have need of a paramedic and/or IV solutions and infusion sets. Air evacuation specialists generally are looked up by clients with a qualified hospital volunteer.
