This study will investigate the effects of a reservoir nasal cannula (Oxymizer®) compared to a conventional nasal cannula (CNC) in patients with idiopathic pulmonary fibrosis.
Patients will be recruited during a 3-week inpatient pulmonary rehabilitation program. They will perform the following three interventions on consecutive days and will repeat them after a week. During these days the time table for prescribed physical activities and therapies will be kept in a comparable fashion. The following 3 interventions will be performed in randomized order: Day A: The Patient wears a conventional nasal cannula for 12 h with oxygen flow rate as prescribed during ADL Day B: The Patient wears the Oxymizer® with prescribed oxygen flow rate for 12 h during ADL Day C: The patient wears the Oxymizer® with a flow rate reduced by 1l/min in comparison to the prescribed oxygen flow rate, for 12h The following week the same measurements will be repeated. The mean of the corresponding two measures will be calculated for each approach.

Oxygen Saturation measurement for 12 h with CNC
Oxygen Saturation measurement for 12 h with Oxymizer®
Saturation measurement for 12 h with Oxymizer® by reduced flow rate (-1l/min)

Schönau am Königssee, Bavaria, Germany
Difference in oxygen saturation between Oxymizer and conventional nasal cannula
Oxygen Saturation will be measured via pulseoxymetry for 12 hours. On 2 days, mean oxygen Saturation will be reported while using Oxymizer or a conventional nasal cannula, both with similar Oxygen flow. The difference of the mean Oxygen Saturation of 12 hours between both cannulae will be the Primary outcome.
Time frame: day 1 to 13
