[External respiration function in patients with exudative pleurisy before and after video-thoracoscopic operations].

57 patients with exudative pleurisy were observed. Function of external respiration was examined with traditional spirometry and a new method--distant spirometry. Function of cardio-vascular system was examined with electrocardiography and echocardiography. The new method of monitoring permits to perform repeated and daily examinations of external respiration function. The method is highly informative, sabe, physiological, permits to evaluate general and isolated ventilation of the lungs simultaneously, and demonstrates dynamics of exudate accumulation that may help in choice of treatment policy.
