Chronic Obstructive Pulmonary Disease Severe Clinical Trial
Effects of Supplemental Oxygen Delivery Via Portable Oxygen Concentrator (Activox™4L) vs. Liquid Oxygen Device in Hypoxemic COPD Patients - a Non-inferiority Study
Taken recent literature together, there is a sufficient number of trials investigating the
effect of different oxygen devices. However, studies comparing oxygen delivery via portable
oxygen concentrator (POC) and liquid oxygen device (LOD) with appropriate exercise testing
and sufficient power are missing.
Given that walking is the most important activity of daily life to preserve the maintenance and to participate in social life, we aim to investigate the effects of two different oxygen delivery systems during walking in hypoxemic COPD patients (POC vs. LOD).
The endurance shuttle walk test (ESWT) is well validated for measuring endurance walking capacity in COPD patients with good repeatability. The advantage of this test over the 6MWT is that the ESWT is performed at 85% of the individual maximum which is close to the intensity of typical daily activities. Due to the fact that the ESWT enables us to determine the maximum duration of exercise and to compare values at isotime (at the point of time when the shortest of the 3 ESWTs ends), we use the ESWT as exercise test in our trial.
