Individuals who are flown by airevac businesses do not have the ability to be transported on your common flights …. because they are in need of advanced cardiac life support. The cases need a breathing machine and an ACLS trained flight staff and flight paramedic – and accordingly these are the patients who can not be sent by the the public airplane services. As they do not want to go on public air travel services — because these individuals are not in medically stable condition , private air ambulance crews must be used. Almost all air ambulances are designated as being charter operations that are privately owned. The cases sometimes will look for fixed wing air ambulance establishments with a case work specialist. When hospitalized patients are unable to fly with the public airplane charters . That is due to the fact that these are patients that are in need of a nurse , or an IV monitor and care for special medicine, there are crews that help transfer patients in emergency cases.
