Brief summary
The purpose of this study is to compare pharyngeal FiO2 in day time with nasal normobaric O2 with inhaled FiO2 in the night time with home care ventilator NIV at the same O2 flow.
Detailed description
in a prospective observational study the investigators will register FiO2 in 15 voluntaries COPD patients as following: * Pharyngeal FiO2 (G5® Philips™ side stream FiO2) with O2 supply through nasal cannula at basal flow (flow needed by patient). In order to compare FiO2s the investigators will measure FiO2 with 150%, 75%, 50% and 25 % of basal Flow * And FiO2 during nocturnal NIV (pressure support ventilation; Vivo 50®, Bréas™), using facial or nasal masque (Confort Gel® Respironics™). O2 flow will be basal flow.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference in FiO2 measured during NIV compared to the FiO2 measured during day time with nasal canula at similar O2 flow | 18 hours |
Secondary
| Measure | Time frame |
|---|---|
| Time spent below different O2 levels during NIV despite constant O2 flow and their correlation to day time FiO2 with nasal canula | 18 hours |
| levels of O2 adjustment needed to keep FiO2 stable with NIV | 1 hour |
