[Pulmonary hemodynamics and external respiratory function in patients with chronic obstructive lung diseases. The diagnostic value of complex radiologic study]. / Legochnaia gemodinamika i funktsiia vneshnego dykhaniia u bol'nykh khronicheskimi obstruktuvnymi zabolevaniiami legkikh.

A study made of the external respiration function and pulmonary hemodynamics in 43 patients with chronic obstructive pulmonary diseases by fluorography and tomography disclosed highly significant signs of impairement of the external respiration function and pulmonary hemodynamics at early stages in the course of these conditions' development. The above findings are confirmed by a series of non-invasive techniques of investigation, such as radiopulmonography, jugular phlebography, tetrapolar pulmonary rheoplethismography.
