Manned Testing of the Superlite 17B Diving Helmet with the Oronasal One-Way Valve Removed.

Abstract

The Diving Systems International Superlite 17B helmet underwent manned failure-mode testing at simulated depths of 30 and 856 feet of seawater during air bounce dives and a helium-oxygen saturation dive in the Ocean Simulation Facility. Twenty-three graded exercises (50-150 watts) were performed by seven subjects with either the helmet in normal configuration or with the one-way oronasal valve removed to simulate a worst case single failure. There was no significant difference in maximum end tidal CO2 between the two configurations. (Author)
