[The hemodynamic status during ultraviolet irradiation of the blood in patients with chronic nonspecific lung diseases].

Central and organic hemodynamics were studied in extracorporeal UV irradiation of blood (EUVRB) conducted in patients with chronic nonspecific diseases of the lungs. Within the first postexposure day the majority of the hemodynamic parameters showed marked fluctuations. EUVRB brought about a persistent reduction in pulmonary-vascular resistance in bronchial asthma and chronic obstructive bronchitis patients. The latter also achieved a decline in pulmonary hypertension. A positive trend arose after EUVRB in red cell histo- and morphograms. Relevant hemodynamic EUVRB mechanisms are discussed.
