[The relationship between the state of the pulmonary circulation and indices of cerebral gas exchange in patients with acquired heart defects].
The author studied the state of hemeostasis in normals and in patients with acquired heart insufficiency. By means of bloody methods of triple probe samples of the blood inflow and outflow from the brain, and by biochemical methods they also studied 22 normals and 100 patients with acquired heart insufficiency for interrelations between the gas metabolism indices and acid-base equilibrium of the central pulmonary hemodynamics. As a results it was established that the brain blood flux in patients with acquired heart insufficiency in different degrees of pulmonary hypertension is adequate to the metabolic requirement of the brain in oxygen and corresponds to identical indices in normals. There was no relation between the state of pulmonary circulation and brain circulation.
