Design outcomes

Primary

Measure	Time frame
Method comparison of PaO2 (arterial partial pressure of PO2) to PcO2 (capillary partial pressure of PO2) serves as the primary outcome parameter	—

Secondary

Measure	Time frame
•method comparison in PO2 = 55 mmHg •method comparison of SpO2, ScO2 and SaO2 •comparison of the painfulness of the two puncture techniques (arterial and capillary) via visual analogue scale (VAS) •pneumological assessment: spirometry, full body plethysmography, diffusing capacity test	—
