Evaluation of Newly Computed Helium-Oxygen Decompression Tables at Depths Greater than Provided for in the Published Tables,the Effectiveness of the Improved Recirculation System and the Feasibility of Accomplishing Useful Work by Highly Trained and Conditioned Divers at these Depths,

摘要

Forty-nine multipurpose pressure exposures were made in the helium-oxygen diving helmet. These dives were made to check newly computed helium-oxygen decompression tables for deep depths,evaluate an improved gas recirculation system and determine if useful work could be accomplished at deep depths by highly trained and conditioned divers. Results indicate that the accepted physics of decompression is not valid for working dives to depths in excess of 430feet. The present gas recirculating system of the helium-oxygen helmet adequately provides for the removal of CO2and allows divers to do useful work at the depths tested. (Author)
