There generally are hospitalized patients who look for transportation from airevac charters because of the fact that these men or women are unable to go by the usual airplanes. As these people do not want to go on the public airline establishments . This sometimes is on account of the fact that they are not in non critical circumstance , air evacuation businesses have to be contracted. Often there are individuals who necessitate an IV monitor and care for narcotics , and/or an advanced cardiac life support flight staff ; and consequently they are unable to go by the public air travel charters. From time to time there are air evacuation fleets which do exist anywhere in the world. Many outpatients occasionally will try to find airevac companies without the helping hand of a trained hospital volunteer.
