Abstract : 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 430 feet. The present gas recirculating system of the helium-oxygen helmet adequately provides for the removal of CO2 and allows divers to do useful work at the depths tested. (Author)
