Evaluation of a Full Face Mask for Incorporation into the Swimmer Life Support System MK 1.

Abstract

The (SLSS) MK 1 with the Full Face Mask (FFM) was tested for its ability to support a diver performing sustained heavy work at operational depth. During exercise sequences, measured parameters were the diver's heart rates, oral-nasal mask differential pressures, and the oxygen and carbon dioxide fractions of inspired and expired gas. Analysis of the data clearly demonstrates that the system supports a working diver without causing either a decrement in work performance or abnormal retention of carbon dioxide. In addition, it was demonstrated that the external resistance to breathing was significantly lower with the FFM-hose assembly compared with similar data obtained with the MK VI Mod 0 mothpiece-hose assembly.
