Nearly all airevac services are privately ran . Elderly men and women that obtain help from medevac services call for a flight staff. Medivac businesses are researched by clients without the helping hand of a social worker. As they can not be taken on public airplanes —- because they are not in stable situation , private air ambulance charters must be coordinated with. Those few people call for a paramedic and/or a complete ICU/CCU setup — and these are the people that are not good to be moved on the everyday commercial air travel charters. There sometimes are medical air evacuation operations who are available to be hired within the United States.
