Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary Outcome: - specificity - sensitivity - positive and negative predictive value of the quotient of ascending slopes (SIII / SII) at a cut-off-value = 0.10 for the detection of an existing airway obstruction In comparison with bodyplethysmograpy results (indicating airway obstruction FEV1 < 70% of normal, pathological sRAW / RAW) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome: - sensitivity - specificity and - predictive values of other ascending slope quotients that can be identified with a ROC-analysis. Moreover the correlation between capnovolumetry and the parameters of the bodyplethysmography will be investigated in an exploratory manner in order to determine a possible additional benefit in the detection of emphysema and increased dead space volume. | — |
