- Primary Outcome Measures
Name Time Method - Measurement with / without nalas strip, or which nasal strip was applied<br>- Result of rhinomanometry:<br>a) Inhaled and expiratory nasal flow [ml / s] with fixed reference pressure 150 Pa for the right and left nasal side separated<br>b) Flow Increase: increase of the respiratory flow as a percentage increase of the flow values at 75 and 150 Pa [%]<br>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]<br>- Result of rhinoresistometry:<br>a) nasal breathing resistance at a flow rate of 250<br>ml / s<br>- Result of acoustic rhinometry:<br>Cross-sectional areas of MCA1 and MCA2 in [cm²]<br>Nasal Volumes Vol 1 and Vol 2 [cm³]
- Secondary Outcome Measures
Name Time Method Result of Rhinresistometry:<br>b) hydraulic diameter as a measure of the width of the nose [mm]<br><br>c) friction coefficient in and expiratory, reference to the turbulence formation in the nose
