Effect of Short-term Oxygen During CPET in COPD

August 12, 2019 updated by: University of Zurich

Effect of Short-term Oxygen Therapy on Cardiopulmonary Exercise (CPET) Capacity in Patients With Chronic Obstructive Pulmonary Disease (COPD)

In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with chronic obstructive pulmonary disease.
