Altitude decompression sickness susceptibility: influence of anthropometric and physiologic variables.

摘要: Introduction: There is considerable variability in individual susceptibility to altitude decompression sickness (DCS). The Air Force Research Laboratory Altitude DCS Database consists of extensive information on 2980 exposures conducted with consistent procedures and endpoint criteria. We used this database quantify the variation determine if anthropometric and/or physiologic variables could be predict risk. Methods: were 240 subjects who participated at least 4 70 exposure profiles which between 5 95% all tested developed symptoms. A subject/study ratio (SSR) was calculated by dividing experienced a subject during their incidence for identical exposures. SSR identify relative use analyzing possible relationships height, weight, body mass index, age, percent fat, aerobic capacity. Results: 46.5% 1879 subject-exposures exposed times. significant relationship existed higher combination lower capacity greater weight (p < 0.05). Discussion: Despite correlation, less than 13% accounted best variables, Vo 2 max. Conclusion: Differences cover wide range appear related some variables. However, there insufficient correlation allow prediction an individual's susceptibility.
