In this study we have compared the sensitivity and reproducibility of nasal airways resistance measurements made using an oscillometer, with those made by passive anterior, active anterior and active posterior rhinomanometry. Nasal airways resistance values were compared in 12 patients with rhinitis and 15 normal subjects, of whom ten had additional measurements after a vasoconstrictor spray, oxymetazoline. The coefficients of variation of 6-8 technically satisfactory measurements were 9-19%. The decongestant effect of oxymetazoline was detected by all methods, with no decrease in reproducibility. Post vasoconstrictor nasal airways resistance fell by 28% (passive anterior), 35% (active anterior), 36% (active posterior) and 58% (oscillometry). In conclusion, the oscillation method for deriving nasal airways resistance is a useful, new, simple and noninvasive way of assessing nasal airways patency. Results compare favourably with other, more established techniques.
在本研究中，我们比较了使用示波仪测量鼻气道阻力的敏感性和可重复性，以及被动前鼻测压法、主动前鼻测压法和主动后鼻测压法所测结果。我们对12例鼻炎患者和15名正常受试者的鼻气道阻力值进行了比较，其中10名正常受试者在使用血管收缩剂喷雾羟甲唑啉后又进行了额外测量。6 - 8次技术上令人满意的测量的变异系数为9 - 19%。所有方法均检测到了羟甲唑啉的减充血效果，且可重复性未降低。血管收缩剂使用后，被动前鼻测压法测得的鼻气道阻力下降了28%，主动前鼻测压法下降了35%，主动后鼻测压法下降了36%，示波仪测量法下降了58%。总之，通过振荡法得出鼻气道阻力是一种有用、新颖、简单且无创的评估鼻气道通畅性的方法。其结果与其他更成熟的技术相比更具优势。
