The respiratory system state in 52 patients with chronic cardiac diseases and cardiac insufficiency, in 64 patients with chronic pulmonary diseases and pulmonary insufficiency is studied. As many as 28 patients without cardiac and pulmonary diseases are examined as the control group. The group of patients with combination of cardiac and pulmonary diseases is distinguished. The reliability estimation of differences of the data obtained in the compared groups of patients is performed to determine the most reliable indices of external respiration function for differential diagnosis of chronic cardiac and pulmonary insufficiency. The indices of respiration median relations of ventilation to blood flow and uniformity of alveolar ventilation may be used in differential diagnosis of chronic cardiac and pulmonary insufficiency.
