[Respiratory and hemodynamic disorders in the participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].

After examination of cardiorespiratory function in 10 males exposed to Chernobyl accident unfavorable factors at the age of 31-45 years suffering from chronic obstructive bronchitis (7 cases) and mixed bronchial asthma (3 cases) it was established that the patients had ventilation disorders of mixed genesis (moderate obstructive and respiratory affections), frequently occurring decreased specific diffusion (DLCO/Va) in normal total diffusion capacity of the lungs, inefficient gas exchange, midly declined left ventricular pump capacity and contractility. In the above patients a relationship was found between parameters of central hemodynamics assessed at echo-CG and severity of ventilation impairment and respiratory insufficiency.
