[The principles of investigation of nasal resistance by active rhinomanometry].
Anterior (ar) and posterior (pr) active rhinomanometry is the most common technique for assessment of nasal resistancy. The curve presents the interdependence of physiological transnasal pressure and air nasal flow. Following the Versick and Clement polynominal mathematical model (delta P = K0+K1V+K2V2,0) as well as the Broms polar coordinate model best fit the recorder pressure flow data. Computer simultaneously draws the pressure/flow curve and calculates resistance at particular pressure points (75, 150, 300 Pa in ar and 50, 75, 100 Pa in pr). The paper also presents indications for application of rhinomanometry and methodology of its execution.
