[State of circulating blood volume, blood components and the function of external respiration in lung cancer].

The data concerning the changes in the circulating blood volume, globular and plasma volumes, red blood cells indices and also some indices of the external respiration function in lung cancer cases are set forth. Radiopneumography has permitted to find out some significant disorders in the regional ventilation and in the pulmonary blood flow in early postoperative period, which in case of hypoventilation is likely to cause a severe respiratory insufficiency and, therefore, requires an energetic therapeutic control.
