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
