[Measurement of nasal resistance using the oscillation method (author's transl)].

The nasal resistance of 15 healthy subjects aged 12 to 45 years was measured using the spontaneous flow method (Rhinomanometer A 440) and a new variation of the external flow method, namely the oscillation method (Siregnost FD-5). The results of both types of methods were so similar, that the methods can be interchanged for one another. In comparison to the spontaneous flow method, the oscillatory external flow method has the advantage of being simpler to carry out. In addition, there is little stress to the patient that it is especially suitable for children.
