Breathing Characteristics Study.

Abstract

The report describes the evaluation of a technique for measuring the respiratory characteristics of underwater breathing apparatus using a mechanical breathing machine. The technique considered was one used successfully at Yale University to examine the respiratory response of guinea pigs to drugs. Using it, breathing resistance, compliance, and time constant are computed in real time from continuous measurements of tidal volume, air flow rate, and pleural pressure. This technique was tested under a variety of conditions and was shown to be unsuitable for use in the evaluation of underwater breathing apparatus. (Author)
