Abstract

A method of compensating for non-metabolic changes in respiratory or blood gas parameters including generating a compensatory signal based on the magnitude of the non-metabolic change and the amount of time elapsed since the onset of the non-metabolic change. The method of the present invention is useful for compensating for non-metabolic changes in non-invasive carbon dioxide elimination measurements and, particularly, when carbon dioxide elimination is employed to determine cardiac output on a non-invasive, continuous basis.
