Abstract
Cardiac output of a test individual is determined in a noninvasive method, by processing CO.sub.2 expirogram data obtained from the individual. The method also noninvasively determines pulmonary arterial blood CO.sub.2 concentration for the test individual. An apparatus for carrying out this noninvasive method includes a database of computed numerical CO.sub.2 expirograms, a device for measuring experimental CO.sub.2 expirogram data and means for processing the data sets to determine cardiac output.
