Statistically Based Decompression Tables IX: Probabilistic Models of the Role of Oxygen in Human Decompression Sickness.

摘要: Abstract : While probabilistic models of human decompression sickness (DCS) have been successful in describing both the level and timing DCS risk a wide variety N2-O2 data, they failed to account for observed currently available collection dives with significant periods 100% oxygen breathing. The best model date, calibrated over 2300 air dives, under-predicts these O2 by 60%, whether is breathed during in-water or surface procedures. This overestimation benefit 0 due an exaggerated acceleration N2 wash-out 02 Seven-hundred twenty-nine were added calibration data set. Fitting existing base new combined set resulted some improvement OCS prediction n but predictions remained about 30% below level. Three classes 02-specific modifications proposed: (1) modification inert gas kinetics as function pressure, (2) direct contribution either O pressure fraction.
