OBSTACLES IN OXYGEN TRANSPORT DURING AEROMEDICAL EVACUATION,
Abstract
Aeromedical evacuation is well tolerated by the majority of casualties evacuated from Viet Nam to Japan. Low cabin altitudes are better tolerated by all injury types. Cabin altitudes of 6,700 and above are poorly tolerated by the S.I. and V.S.I. (22% of all evacuees). The most hypoxemic patients during flight were those with fractured femurs, multiple extremity fractures and abdominal cases. The lowest tolerance to flight was observed in those who were very seriously injured, regardless of the injury sustained, those with burns, sepsis and patients with chest injuries. Primary determinants of hypoxemia were cabin altitude and preflight pulmonary insufficiency. Of significance but of secondary importance were the patient's level of anemia, low serum osmolality and the type, seriousness and complications of injury. (Author)
