Development of the Partial Pressure of Carbon Dioxide During Exercise and at Night in Patients With Chronic Obstructive Pulmonary Disease (COPD) IV

The aim of this study is to investigate the development of partial pressure of carbon dioxide during the 6-min walking test and during night in Chronic Obstructive Pulmonary Disease (COPD)-patients (GOLD stage IV). Therefore the partial pressure of carbon dioxide, oxygen saturation and the heart rate are registered by a device called "Sentec" during the mentioned periods. In addition a measurement of activity is realised by an activity monitor ("Sensewear").
