INCIDENCE OF LOSS OF CONSCIOUSNESS IN 1,980 AIR FORCE PERSONNEL

摘要

To learn the incidence of loss of consciousness among members of the United States Air Force military population four different surveys have been carried out to included 1,578 individuals on flying status and 402 Academy cadets (total, 1,980). Anonymous questionnaires indicate that loss of consciousness has occurred in 37.4 percent of rated flying personnel. Loss of consciousness, for reasons other than all types of physical trauma, has occurred in 20.2 percent of the flying population. A wide variety of precipitating factors were described by the individuals surveyed. The results of the surveys indicate that loss of consciousness and syncope are not infrequent events in a healthy flying population. The surveys establish that many pilots have had successful flying careers even the ugh they have, on occasion, experienced loss of consciousness precipitated by innumerable causes.
