The Relationship Between Time Useful Consciousness and Various Physiological Factors in ROKAF Pilots

Abstract
|
|
|
Hypoxia is a serious aviation problem and will be a source of dangerous aerospace accidents. Hypoxia tolerance has been evaluated by the time of useful consciousness (TUC), subjective symptoms, hypoxic ventilatory responses (HVR), and
cardiovascular
changes. It is not clear which physiological factors relate to the former parameters and only few studies are occurred in Korea. From 15 May 1998 through 17 September 1999, 929 ROKAF pilots are checked CBC, blood chemistry, health-related
physical
fitness tests, pulmonary function tests, life-style, and we analyzed the variables showing significant correlation with TUC. Age, total flying time, grade, and smoking duration had negative correlation with TUC. BMI, FVC, TV, and flexibility had
positive correlation. But the reasons why fighter pilots showed significantly shorter TUC than transporter pilots are needed more following study. Also further studies must be made on the intervention study for hypoxia tolerance promotion of
ROKAF
pilots.
