Mathematical models of the nasal airway: ability to discriminate between normal and abnormal static resistive components

Data from subjects with normal and partially obstructed airways were used to compare the goodness of fit and sensitivity to abnormal air flow from Rohrer´s equation and a right hyperbolic equation. The two goodness of fit measures used (adjusted R² and standard error of the estimate) indicate that the right hyperbole did not fit the data significantly better than Rohrer´s equation. Only parameters derived from Rohrer´s equation could discriminate between the normal and partially obstructed airways
