Surface Decompression, Derivation and Testing of Decompression Tables with Safety Limits for Certain Depths and Exposures.

Abstract

A total of 282 dives were made in this project. The tables tested were - 100 feet for 85 min.; 130 feet for 55 min.; 150 feet for 38 min.; and 170 feet for 30 minutes. Work, rest, wet tank and dry chamber dives were made in these tests. Work dives in the wet tank using standard decompression were also made as controls for each of the above depths. Resulting from all dives made were 27 cases of caisson disease which required recompression and 25 cases of mild caisson disease which did not require recompression. Evidence is presented to show the relationship between the site of bends symptoms and the part of the body exercise.
