[Disorders of pulmonary gas diffusion in liver cirrhosis].

Unlabelled: There is no consensus on the pathogenesis and incidence of diffusion disorder in chronic liver diseases. It is supposed that the pathogenic mechanisms responsible for the reduction of diffusion capacity in liver diseases are multifactorial, including: ventilation-perfusion mismatching, diffuse interstitial pulmonary diseases and reduced transitory time in hyperperfused lung areas [1]. The increase of diffusion of oxygen molecules within dilated blood vessels during the inspiration of 100% O2 in patients with liver cirrhosis is called "diffusion-perfusion defect" or "alveolar-capillary oxygen disequilibrium" [3].
