[Estimation of the main indices of external respiration in patients with mediastinal compression syndrome, caused by mediastinal tumors].

The results of estimation of the external respiration function (ERF) in 334 patients, treated in 1992-2007 in the clinic for mediastinal compression syndrome, caused by mediastinal tumors (MT), are adduced. There were delineated the main trends of investigation of the pulmonary ventilation capacity in patients with tracheobronchial obstruction, caused by MT. The concept of optimal estimation of ERF in such patients was formulated. The ERF indices estimation permits to determine the ways of operation security enhancement as well as prognosis conduction and prophylaxis of intra- and postoperative complications occurrence.
