ABSTRACT:
An apparatus for introducing test gas commonly containing an inert gas and carbon monoxide to a patient through a mouthpiece which, in turn, is attached to a sample chamber within which are arranged sensors enabling measuring of carbon monoxide, carbon dioxide, an inert gas or other gases. Valving permits the test gas to be inhaled by the patient and then exhaled into the chamber. Further valving at the outlet of the chamber permits evacuation through a gas volume measuring device after measurements within the chamber have been completed. Sample chambers may be of various shapes but preferred forms are essentially linear or closed loop arrangements.
