In 60 patients with stage II-III bronchogenic carcinoma of the lung the following procedures were included in the complex of preoperative functional examination: spiro-body-plethysmography, catheterization of the right heart, and simultaneous examination of gas exchange using a DELTATRAC MBM-100 metabolic monitor. To evaluate the lung diffusion capacity and the dimensions of the arteriovenous shunt, oxygen mixtures differing in O2 concentration were used. The results were interpreted within the framework of a homogeneous model of lung gas exchange realized on a PC/AT personal computer. The interrelationship of ventilation disorders with hemodynamic and lung gas--exchange function was studied. Arterial hypoxemia was mainly observed in obstructive and mixed disorders of ventilation function and was more marked in the latter. Primary disturbance of the lung diffusion capacity was found to be the leading link in the development of acute respiratory insufficiency after the operation. |
