Blood biochemical and cellular changes during decompression and simulated extravehicular activity.

摘要: Blood biochemical and cellular parameters were measured in human subjects before after exposure to a decompression schedule involving 6 h of oxygen prebreathing. The was designed simulate extravehicular activity for (subjects performed exercise while exposed 29.6 kPa). There no significant differences between blood samples from. who susceptible (n =11) versus those resistant = 27) formation venous gas emboli. Although several statistically (P < 0.05) changes observed following the (increases white cell count, prothrombin time, total bilirubin, decreases triglycerides, very-low-density lipoprotein cholesterol, urea nitrogen), small magnitude factor levels remained within normal clinical ranges. Thus, used this study is not likely result that would pose threat astronauts during activity.
