[A computer-assisted study of the effect of gravitation on the functional state of the lungs].
Gravitation influence on lung function was investigated in 115 patients and 21 healthy persons. Changing of an examinee's position from vertical into a horizontal one causes changes in lung function in health and disease. Characteristic features of lung function were determined for each group of examinees in order to improve the diagnosis and differential diagnosis of bronchial cancer and nonspecific chronic pulmonary diseases with a similar x-ray picture. A study of pulmonary ventilation and blood supply of the lungs in vertical and horizontal postures in Hodgkin's disease patients led to a conclusion that irradiation of patients seemed more effective in a phase of deep breath. It made it possible to reduce radiation exposure of healthy parts in a zone to be irradiated.
