Evaluation of the Mark 11 Mod 0 UBA in Cold Water.

Abstract

The MK 11 Mod 0 UBA was evaluated for its ability to efficiently absorb carbon dioxide during prolonged moderate work in cold water. In addition, thermal protection of the absorbent bed and the degree of inspired gas warming were analyzed. The results show that near the surface the apparatus can efficiently absorb CO2 for prolonged periods in cold water, and that the absorbent bed is thermally protected. However, there was a virtual absence of inspired gas warming which may be a limiting factor for a diver at depth. (Author)
