Features of measuring the differential pressure at the active anterior rhinomanometry
The method of active anterior rhinomanometry was described. The influence of losses of differential pressure on calculation of the diagnostic parameter R <sub>150</sub> was analyzed. The relative error of measurement of differential pressure was calculated. The biggest error is observed at R <sub>150</sub> in the normal range and weak obstruction. Figs.: 5. Table.: 1.
