[Mass spectrum analysis of expired and alveolar gas during separate bronchospirometry].

It is possible to measure with a mass spectrometer the oxygen and carbon dioxide pressure in expired gas and alveolar gas in each lungs during a separate bronchospirometry. In 15 cases out of 26 (of which 21 had broncho-pulmonary cancers) it was possible to trace serious disorders of the alveolar-capillary exchanges in the diseased lung, probably related to an altered ventilation-perfusion relationship. This technique brings more data to the physio-pathologist than the plain measurement of the oxygen consumption of the diseased lung.

[Study of pulmonary leucostasis by measurement of the alveolo-arterial CO2 difference (author's transl)].

In order to study pulmonary leucostasis in 18 leukemic subjects, the ventilatory flow from ventilated nonperfused zones (VFVNZ) was measured using alveolo-arterial CO2 difference (28 times). This method proved to be simple and accurate in the follow-up of the patients. The number of white cells necessary to increase the VFVNZ by 1% is very different from one histologic type to another. These results are in agreement with in vitro observations.
