Pulmonary Function in the Patients Submitted to Lung Exeresis

The effects of lung surgery on respiratory function were investigated in 80 patients undering postpneumonectomy and lobectomy for carcinoma and tuberculous of the lung. The lung function showed a reduction to about half the predicted normal values for postpneumonectomy. VG was reduced to 48.2% predicted for right pneumonectomy; FVC was reduced to 49.9% predicted for right pneumonectomy; FEV1 was 41.5% predicted; TLC was 55.4% predicted; RV was reduced to 77.6%; FEF 50 was 17.0%; FEF 25 was 14.3%. It is important that protect lung function of postpneumonectomy.
