[The significance of examination of breathing mechanics during general anaesthesia and artificial ventilation for the complex assessment of functional pulmonary conditions in patients with nonspecific respiratory disease (author's transl)].

The results of mechanical examinations of breathing during bronchoscopy in general anaesthesia with various breathing regimens in 140 patients with chronic nonspecific respiratory diseases are given. The variations of breathing mechanics depend on both the extent of the pulmonary changes and the localization of the obstructive syndrome (large and small bronchi) and they correlate with the clinical severity of the respiratory insufficiency. In comparison with the mechanical examinations of breathing in spontaneous breathing we can find a very good coincidence of the results. The results from 42 patients with expiratory stenosis of the trachea and main bronchi are emphasized. The method mentioned guarantees a reliable judgement of the functional condition of the lungs without an additional annoyance of the patient and also without an essential complication of the bronchoscopic examinations. It makes practical clinical conclusions concerning the treatment and the choice of the suitable anaesthesiologic procedure possible. It has the greatest perspective in the modern pulmonologic hospital.
