[Function in patients with chronic fibrocavernous tuberculosis].
Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, residual volume (RV), R(aw), R(in), R(ex), DLCO-SB, DLCO-SS, PaO2, and PaCO2 were determined in 62 patients with chronic fibrocavernous tuberculosis. Lung dysfunctions were detected in 96.8% of the patients. Changes in lung volumes and capacities were found in 90.3%, impaired bronchial patency was in 90.3%, and pulmonary gas exchange dysfunction was in 79.0%. The lung volume and capacity changes appeared as decreased VC and FVC, decreased and increased TLC, TGV, RV; impaired bronchial patency presented as decreased PEF, MEF25, MEF50, MEF75, and FEV1/VC%; and increased R(aw), R(in), R(ex); pulmonary gas exchange dysfunction manifested itself as reduced DLCO-SB, DLCO-SS, PaO2, and decreased and increased PaCO2. The magnitude of the observed functional changes ranges from slight to significant and drastic with a predominance of considerable and drastic changes in lung volumes and capacities and mild impairments of bronchial patency and pulmonary gas exchange function.
