Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Measurement with / without nalas strip, or which nasal strip was applied - Result of rhinomanometry: a) Inhaled and expiratory nasal flow [ml / s] with fixed reference pressure 150 Pa for the right and left nasal side separated b) Flow Increase: increase of the respiratory flow as a percentage increase of the flow values at 75 and 150 Pa [%] c) inspiratory and expiratory nasal breathing resistance with fixed reference pressure 150 Pa for the right and left nasal side separated, as well as for both nasal sides together ("total resistance") [sPa / ml] - Result of rhinoresistometry: a) nasal breathing resistance at a flow rate of 250 ml / s - Result of acoustic rhinometry: Cross-sectional areas of MCA1 and MCA2 in [cm²] Nasal Volumes Vol 1 and Vol 2 [cm³] | — |
Secondary
| Measure | Time frame |
|---|---|
| Result of Rhinresistometry: b) hydraulic diameter as a measure of the width of the nose [mm] c) friction coefficient in and expiratory, reference to the turbulence formation in the nose | — |
