Digital Computation of Decompression Profiles

Abstract

The Kidd-Stubbs pneumatic analogue decompression computer is used for the real-time prediction of the safe ascent depth following an excursion to depth. The theoretical model which is derived from the decompression computer can be solved using numerical techniques on a digital computer, or can be solved on an analogue computer. This report describes a series of Fortran IV programs which have been written to solve this theoretical model under a variety of conditions. The basic program can be used to calculate the safe ascent depth for a standard dive or for repetitive dives, and if desired, the safe ascent height for flying after diving. Modifications to the basic program are described which permit the use of the model for applications such as the design of pneumatic computers and the analysis of decompression tables.
