ABSTRACT:
The metabolic rate analyzer comprises a flow proportioning valve for producing a proportional sample of the expired gas of the subject being studied. A sample cylinder is provided for drawing a proportional sample of the expired gas of the subject being studied from the flow proportioning valve. A test chamber is provided and an O.sub.2 sensor is provided. The test chamber is provided with a selectively-permeable membrane, the selectively-permeable membrane having a selective permeability for CO.sub.2, whereby CO.sub.2 is selectively vented from the test chamber. The sample cylinder is also used for chrging the test chamber with the proportional sample of the expired gas of the subject. A pressure sensor is provided for monitoring the pressure of the sample and determining the rate of pressure decay in the test chamber due to the selective venting of CO.sub.2 through the permeable membrane. An analyzing means is provided fo determining CO.sub.2 content in the expired gas from the rate of pressure decay in the test chamber, conducting a volumetric analysis of the proportional sample to determine total volume of expired gas, and then correlating O.sub.2 content, CO.sub.2 content and total volume of expired gas to provide a measure of the metabolic rate of the subject being studied.
