Manned Evaluation of the MK 14 Closed Circuit Saturation Diving System.

Abstract : The MK 14 Closed Circuit Saturation Diving System was evaluated over a depth range of 167 FSW to 1100 FSW to test its ability to support a diver performing heavy work. During graded exercise, helmet carbon dioxide, differential pressure, and inspired gas temperature as well as diver heart rate were measured. Analysis of the data indicates that the MK 14 can support a diver performing heavy work (3.0 LPM oxygen consumption), and has successfully met it's design objectives. (Author)
