[Effect of a local disorder of bronchial patency on the circulation and gas exchange in the lungs].


Acute and chronic experiments on dogs have demonstrated the onset of local alveolar hypoxia in disturbed bronchial patency. Alveolar hypoxia caused a rise in the pulmonary vascular resistance. Pulmonary hypertension is predetermined by an increased number of pulmonary zones of hypoxic vasoconstriction due to higher incidence and degree of bronchial… (More)
