  Purpose
The purpose of this study is to evaluate if supplemental oxygen during air travel can be reliably titrated using a Hypoxia-altitude simulation test (HAST). Also, the effect of oxygen supplementation given with the various oxygen equipment allowed for air travel is studied.

Condition Intervention
Chronic Obstructive Pulmonary Disease Other: Pre-flight test with supplemental oxygen

Intervention Details:
    Other: Pre-flight test with supplemental oxygen
    The Hypoxia-altitude simulation test, which is established in clinical practice, is compared to the gold standard of hypobaric chamber while giving supplemental gaseous oxygen without and with oxygen conserving device, and with oxygen concentrator.
    Other Name: Oxygen
Detailed Description:
International guidelines recommend supplemental oxygen if PaO2 < 6.7 kPa (50 mmHg) during air travel. Hypobaric chamber exposure is the ideal test but is not widely available. In clinical practice, the HAST has been recommended as the preferable test for pre-flight evaluation, and is used with increasing frequency. The oxygen dose during air travel has been recommended titrated during HAST. In the study, supplemental oxygen titration during hypobaric chamber exposure is compared to oxygen titration during HAST, to evaluate if HAST can be used with confidence to titrate the amount of supplemental oxygen needed during air travel.
