Abstract

A series of experiments has been designed to evaluate the performance of an oxygen uptake computer. The Model OCC-2500 oxygen uptake computer is an electronic instrument including a mask-sensor assembly and a special-purpose analog computer. Intended for the analysis of respiratory gases in human subjects, the system produces a real-time analog voltage proportional to the oxygen uptake in one minute or other time periods controlled by the operator. Expired air samples, monitored by the polarographic oxygen sensor and mass gas flowmeter of the computer system were simultaneously collected in a gasometer and analyzed by gas chromatography. Oxygen uptake values (200-3200 cc/min) obtained from 15 subjects (297 observations) during rest and after exercise produced a sample correlation coefficient of 0.998. Subjects enjoy virtually unrestrained mobility using the device, in that attachment to monitoring equipment is limited to electrical leads. Personnel support requirements and errors, associated with conventional procedures, are significantly reduced. The compact nature of the device permits application in almost any experimental design situation including presurized suits and underwater studies.
