ABSTRACT A method of determining the mixed venous PCO2 (PvCO2) is disclosed, the method comprising the steps of: (a) measuring the PCO2 of the gases inhaled and exhaled by the patient under controlled conditions without rebreathing; (b) causing the patient to inhale a test gas containing at least a small concentration of CO2 and continuing to measure the PCO2 of the inspired and expired gases, the patient taking at least two breaths without rebreathing; (c) determining the PCO2 of the inspired gases (PICO2) and the end tidal PCO2 of expired gases (PECO2); (d) determining the differences between the end tidal PCO2 and inspired PCO2 under control and test conditions, and relating it to the inspired PCO2 used in the determination of the difference. This relationship can be used to calculate the mixed venous PCO2.
