Brief Summary
For patients with emphysema, lung volume reduction by insertion of endobronchial valves could be an expedient approach to improve the diaphragm function and the strength of breathing muscles. Therefore in the present study investigators intend to examine, whether the lung volume reduction by valves might improve the physical capacity and the quality of life.

Outcome Measures
Primary Outcomes (4)
Breath Muscle Power
Maximal Inspiratory Pressure (PImax)
Change of breathing strength 3 (respectively 9) months after the bronchoscopy
Breath Muscle Power
Maximal Expiratory Pressure (PEmax)
Change of breathing strength 3 (respectively 9) months after the bronchoscopy
Breath Muscle Power
Neuromuscular drive (P0.1)
Change of breathing strength 3 (respectively 9) months after the bronchoscopy
Breath Muscle Power
Sniff nasal pressure
Change of breathing strength 3 (respectively 9) months after the bronchoscopy
Interventions
Independent of the study, subject will get a bronchoscopy with chartis measurement in general anaesthesia. chartis measurement is a Balloon angioplasty. Balloon will be well-positioned in lung and filled by air for occlusion of lobe of the lung. System recognizes collateral ventilation of lobe of the lung via calculation of airflow resistance. Negative result allows the endoscopic placement of selfexpandig endobronchial valves in the subject lung. Inhale airflow will be inhibit an enclosed air and liquids can exhaust.
