Manned Evaluation of the Swimmer Life Support System Mark 1.

Abstract

The Swimmer Life Support System Mark 1 (SLSS MK 1) was evaluated for its ability to support divers performing heavy work at 30, 140, and 210 FSW. Heart rate, mouth differential pressure with respiration, inspired oxygen, and inspired carbon dioxide levels were monitored. Results indicate that oxygen and carbon dioxide levels were adequately controlled at all depths and work rates, but breathing resistance was excessive at 210 FSW when the breathing gas was nitrogen-oxygen. Because of this and because of nitrogen narcosis considerations, the operational depth was subsequently limited to 150 FSW for nitrogen-oxygen breathing. (Author)
