Computer-Assisted System for Determination of O2 Consumption and Co2 Production in Man.
Abstract
Determination of oxygen and carbon dioxide production rates are routinely made in the exercise physiology laboratory. A semi-automated, portable system based on a desktop computer has been developed. Expired gas from several breaths, collected in a bag, has its volume measured with a spirometer. The oxygen and carbon dioxide concentrations are directly read by the computer from the appropriate gas analyzers. The computations needed to evaluate oxygen consumption, carbon dioxide production and respiratory exchange ratio are automatically performed and the results immediately displayed. Measured volumes are accurate + or - 0.010 liters absolute and gas concentrations are reproducible to + or - 0.01% absolute. The system is technically simple and can be learned quickly by even relatively inexperienced operators.
