An Improved Respiration Magnetometer for Laboratory and Diving Studies

Pagination or Media Count:
A model of a respiration magnetometer, similar to one described by Mead, was constructed at the Submarine Medical Research Laboratory in Groton, Connecticut, and has been modified recently for greater reliability and ease of operation. Good correlation between output signal and lung volume was found with supine subjects giving the most consistent results. The advantage of operation without mouthpiece, mask, or neck seal, and the instruments insensitivity to environmental changes, make it particularly promising for prolonged studies of gas exchange and for hyperbaric research. A system for streamlined calibration and data reduction is proposed.
