ABSTRACT
The paper shows that some patients with disseminated pneumo- and pleurofibrosis and pulmonary emphysema, which have developed in chronic specific and nonspecific lung diseases, have severe local disorders of respiratory biomechanics, which appear as the paradoxical ventilation phenomenon It also indicates that these abnormalities can be identified by the rather easy-to-use and accessible technique, regional rheography of the lung. The significance of detection of the paradoxical local ventilation phenomenon for clarifying the mechanism responsible for ventilation disorders is illustrated by a clinical note.

Resulting from complex preoperative clinico-functional examination of the 50 patients with generalized fibro-cavernous pulmonary tuberculosis, it was established that inclusion of compensatory mechanisms of the cardiovascular and respiratory systems was due to the development of chronic failure. Direction, pronouncement and interrelation of the main parameters of external respiration, oxygen transport and hemodynamics are determined by a degree of hypoxia.

Substantiation is given to the approach to the differential prescription of helium-oxygen gas mixtures with a different oxygen concentration for relieving respiratory hypoxia which develops in the obstructive and restrictive types of ventilation abnormalities.
