Virtually all air ambulance services are designated as being business organizations that are privately run. Once in a while there are hospitalized patients that are diagnosed as being in a stable condition yet they are acutely restrained by their illness, so medevac companies arrange an air evacuation together with their customers. Jet ambulance fleets generally can be found by families of patients with the case managers suppliers list. As they are dependent on a full emergency care setup , and/or a RT(Respiratory Therapist) , med flight companies are a necessity. There are cases that are in need of a flight EMT — and consequently they do not have the ability to go by normal airline companies. It is general knowledge among those who do social work for hospitals that victims of major illnesses obtain the service of medivac outfits.
