Objective: To assess the minimal nasal air-flow value, necessary to provide comfort of nasal breathing in patients with seasonal allergic rhinitis.

Patients: 125 subjects with seasonal allergic rhinitis aged 15-60 years and 30 healthy volunteers.

Methods: Measurement - anterior active rhinomanometry (Rhinotest MP-500) at differential (narichoanal) pressure 75 Pa. Data processing - Method 1: mathematical modelling of data distribution with AUC calculation. Method 2: self-developed software based on algorithms allowing to avoid errors of parametric statistics. Comparison of both methods used to find the predictive value.

Results: The minimal nasal comfort providing air-flow value computed according to the Method 1 was 379 cm3×s-1; and according to the Method 2: 308-314 cm3×s-1.

Conclusions: Analysis of data obtained in comparison to results of control group let me to propose a provisional system of interpreting rhinomanometry results in Polish population, where to date no population-oriented norms are available. This system might be helpful in case when clinical data are contradictory or not available. According to this system, total flow values higher that 390 cm3×s-1 might be considered as "normal", nasal flow of less than 280 cm3×s-1 - as "pathologic"; i.e. as limiting nasal comfort. The range 280-390 cm3×s-11 is an "area of uncertainty".
