Abstract |
An approach to estimating the probability of decompression sickness (DCS) in astronauts performing extravehicular activities (EVAs) is described. Data from 66 hypobaric chamber tests (211 cases of DCS in 1075 exposures) were analyzed. Variables considered were denitrogenation prior to decompression, magnitude of the decompression, exercise after decompression, and length of the EVA. Probability models were fitted using techniques from survival analysis. Constant probability of DCS was better described by tissue ratios that decrease as ambient pressure after decompression decreases, a conclusion supported by other studies. |
