Summary

The aim of the study is to find out how blood gas parameters change under the use of surgical mask, FFP2 masks and FFP3 masks (with and without exhalation valve) in patients with known lung disease and long-term oxygen therapy. In particular, the question arises whether patients become hypoxemic or hypercapnic by using a mask. Or whether wearing a mask increases oxygen saturation by its reservoir function.

Conditions

• Face Mask
• Longterm Oxygen Therapy

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	6-MWT	Measurement of saturation and blood gas parameters under 6-MWT with different masks.
DIAGNOSTIC_TEST	Spiroergometry	Measurement of saturation and blood gas parameters under spiroergometry with different masks.
