Nasal airway resistance in 421 normal adults were investigated via anterior rhinomanometry. It was found that the normal value of total NAR in normal adults ranged from 0.126-0.328kPa.s/L (1.29 to 3.35 cmH2O.s/L with normal fluctuations not more than 0.103kPa.s/L (1.05 cmH2O.s/L). The total NAR had a tendency to decrease with ageing, and showed no significant differences between male and female in different age groups (P greater than 0.05). Typical nasal cycles appeared in 80% of normal adults giving rise to alternative changes of bilateral NAR, but the total NAR remained in rather constant ranges.
通过前鼻测压法对421名正常成年人的鼻气道阻力进行了研究。结果发现，正常成年人总鼻气道阻力的正常值范围为0.126 - 0.328kPa·s/L（1.29至3.35cmH₂O·s/L，正常波动不超过0.103kPa·s/L（1.05cmH₂O·s/L）。总鼻气道阻力有随年龄增长而降低的趋势，且在不同年龄组中男性和女性之间无显著差异（P大于0.05）。80%的正常成年人出现典型的鼻周期，导致双侧鼻气道阻力交替变化，但总鼻气道阻力仍保持在相当恒定的范围内。
