Official Title: The Effect of Non-invasive Ventilation on the Oxygenation of Peripheral Muscle Tissue, Cardiovascular System and Exercise Capacity in Hypercapnic COPD Patients
Brief Summary: In this study, 20 hypercapnic COPD patients will perform two constant workrate endurance cycle tests. One test will be while using non-invasive Ventilation (NIV) support, one without in a randomized cross-over design. The aim is to measure, whether NIV is able to change peripheral and respiratory muscle oxygenation.
