Primary Outcome Measures

Name	Time	Method
Simultaneous recording of the respiratory flow curves from nasal cannula measurements (flow measurement technology for sleep apnea diagnostics) and from pneumotachographic measurements (flow measurement technology for therapy initiation) of at least 100,000 breaths and subsequent comparison of the contour curves for consistency

Secondary Outcome Measures

Name	Time	Method
Calculation of obstruction coefficients (= measure for determining the degree of obstruction) from respiratory flow curves of nasal cannula measurements and simultaneously recorded pneumotachographic measurements of at least 100,000 breaths and subsequent comparison for consistency.
