[Measurement of nasal oscillatory resistance].
The usefulness of a new forced oscillation measuring technique for establishing the airway resistance measured nasally, was investigated in 40 patients. Forced oscillation measurements of airway resistance employing the custo vit and Siregnost FD 5, the interruptor technique and classical rhinomanometry for the measurement of nasal resistance, were compared. The correlation of the data of the nasal and bronchial resistance is significant between custo vit on the one hand, and the Siregnost FD 5 and rhinometry on the other. The forced oscillation technique employing the custo vit and the use of a facemask under conditions of normal breathing is, accordingly, a reliable method for determining nasal resistance. The spectrum of application of the equipment is thus expanded from spirometry to rhinomanometry, and its usefulness in nasal provocation testing confirmed.
