Decompression Mechanisms and Decompression Schedule Calculations.

Abstract

A theoretical method has been developed to predict space craft and space suit atmospheres. The method used to analyze stage decompression procedures which have been tested for the Shuttle. The effect of exercise during compression and bottom time has been studied with rats during an 18 minute air dive at 350 fsw. Seventeen resting rats and 27 exercising rats out of 2 groups of 108 rats developed decompression sickness. A method for developing decompression schedules for helium/oxygen and nitrogen/oxygen saturation dives is described. Only one unknown constant is required for each saturation depth and inert gas, and this constant can be estimated from the results of previous saturation dives. Equations are presented for analyzing previous dives and for calculating decompression schedules, and examples of provisional schedules are given.
