Abstract:

The Prototype MK 12 SSDS, Helium-Oxygen System was evaluated to test the ability of the system to support a diver performing sustained heavy work, and to establish the life expectancy of the carbon dioxide absorbent bed. During graded exercise the divers heart rate and helmet CO2 levels were measured. During cannister studies, the cannister effluent was continuously monitored for CO2. Analysis of the data revealed that the system can support a diver performing heavy work 3.0 LMin O2 consumption. However, the carbon dioxide absorbent bed was shown to have a life expectancy incompatible with operational dives at normal working depths. Author
