In recent years there has been growth in international tourism, particularly in air travel. This has been reflected in a profusion of activity in the aeromedical transportation of patients. Pre-hospital medical care has also developed rapidly, with helicopters in use with many of the emergency services. This work addresses relevant issues of the special physical, physiological and psychological stresses that are important in the flight environment. It describes, in detail, the conditions which are susceptible to this form of transport and how patients may be safely and efficiently carried. Much of the text's content is devoted to clinical matters. Administration and organization are also discussed, but are addressed from the standpoint of the clinical aeromedical escort.
