Title Modeling the effects of exercise during 100% oxygen prebreathe on the risk of hypobaric decompression sickness
Bibliographic information Mar. 1997, Vol.68, No.3, p.199-204. 23 ref.
Abstract Previous studies on the effect of exercise during oxygen prebreathe on the incidence of hypobaric decompression sickness (DCS) were analyzed, and a statistical model was developed as a predictive tool for DCS. A dose-response probability tissue ratio (TR) model was created for two groups: prebreathe with exercise and resting prebreathe. Results suggested that exercise during prebreathe increases tissue perfusion and nitrogen elimination approximately 2-fold and markedly lowers the risk of DCS. The model provides a useful planning tool for developing appropriate prebreathe exercise protocols and for predicting DCS for astronauts.
