[Spirometric course control after lung surgery].

72 patients who had undergone pulmonary resection for different causes and of varying degree were followed up by spirometry over a period of two years at 6-month intervals. The patients were allocated to groups according to the preexistent bronchiolar obstruction and extent of lung resection. FEV1 was found not to be essentially altered by surgery. The adaptation of lung function takes at least one year. Ventilatory reserves remain sufficient. The measured spirometric values in pneumonectomized patients two years after operation are 10% above predicted values.
