Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients will be recruited during an inpatient pulmonary rehabilitation program. They will perform three shuttle walk tests on three consecutive days (see below). While performing those tests, the patient's prescribed oxygen flow rate is applicated either through the conventional nasal cannula (CNC) or the Oxymizer.On the first day, patients perform an incremental shuttle walk test to determine maximum walking speed using a conventional nasal cannula.

On two consecutive days, patients will perform two endurance shuttle walk tests at 85% of the maximum incremental shuttle walk test speed. Supplemental oxygen will be provided via nasal cannula at the prescribed oxygen flow rate. Patients will be randomly assigned to perform one test with the Oxymizer and the other one with a conventional nasal cannula.
