Threshold altitude resulting in decompression sickness.

摘要: A review of case reports, hypobaric chamber training data, and experimental evidence indicated that the threshold for incidence Altitude Decompression Sickness (DCS) was influenced by various factors such as prior denitrogenation, exercise or rest period exposure, in addition to individual susceptibility. Fitting these data with appropriate statistical models has potential estimating frequency occurrence DCS at altitudes under different conditions allows us examine influence on DCS. This approach illustrated logistic regression analysis below 9,144 m (30,000 ft). Estimations using regressions showed a noprebreathe, 6-h simulated extravehicular activity profile, symptoms occurred approximately 3,353 (11,000 ft); while no-prebreathe, 2-h exposure profile knee-bends exercise, 7,925 (26,000 These examples definition altitude should be qualified particular combination variables which it observed.
