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.
使用自然流量法（鼻阻力计A 440）和外部流量法的一种新变体——振荡法（西格纳斯特FD - 5），对15名年龄在12至45岁的健康受试者的鼻阻力进行了测量。两种方法的结果非常相似，以至于这两种方法可以相互替换。与自然流量法相比，振荡外部流量法具有操作更简单的优点。此外，对患者造成的压力很小，特别适合儿童。
