Use of the maximum likelihood method in the analysis of chamber air dives.

摘要: Abstract : The method of maximum likelihood was used to evaluate the risk decompression sickness (DCS) for selected chamber air dives. parameters two mathematical models predicting DCS were optimized until best agreement (as measured by likelihood) corresponding observed incidents from a series dives attained. data consisted 800 man-dives with 21 and 6 occurrences marginal symptoms. first model investigated based on nonlinear gas exchange in arrangement four compartments. second mono-exponential parallel overall statistical success describing quite similar models. Predictions safety not part original differed due differences kinetics. For short, no-decompression dives, compartments predicted lower incidence DCS. These predictions more consistent outcome subsequent testing than compartment model. also those single-compartment, two- exponential that evaluated over 1700 U.S. Navy.
