Computer Algorithms Used in Computing the Mk 15/16 Constant 0.7 ATA Oxygen Partial Pressure Decompression Tables.

Abstract

(U) The computer algorithms used in computing the MK 15/16 Constant 0.7 ATA Oxygen Partial Pressure Decompression Table are presented. These algorithms were used to compute both the nitrogen-oxygen and helium-oxygen tables. No physiological rationale or test results are presented. Two model independent input-output programs are presented which can be used with any decompression model which can be written in the prescribed 8 subroutines. One input-output program outputs each decompression schedule in a very detailed format while the other outputs schedules in U.S. Navy Decompression Table format. The 8 subroutines comprising the current MK 15/16 Decompression Model are presented in detail. Where changes in the Decompression Model were made, all versions of the appropriate subroutines are presented. All versions of the program used for computing ascent criteria are presented as well as tables of all ascent criteria actually used in the development of the current MK 15/16 Decompression Model. Annexes contain complete listings of all programs in the Fortran IV language. (attached error correction)
