END TIDAL GAS SAMPLING IN DIVING RESEARCH

Abstract

The possible use of the Rahn Sampler and the Experimental Diving Unit-developed electromechanical sampling system, for obtaining reliable endtidal gas samples from subjects in physiological studies under pressure under water, was studied. It was found that the Rahn Sampler was unsuitable with submerged subjects, but in the dry state the system works well at increased pressures as well as at normal barometric pressures. The Experimental Diving Unit System obtains reliable endtidal samples from submerged subjects when operated manually; an automatic feature obtained reliable samples only with the pressure tank dry, and using the recompression chamber.
