Nasal airway patency and nasal clearance were measured bilaterally on six different test days in ten subjects. Nasal patency was evaluated using anterior rhinomanometry and clearance was measured using a dyed saccharin method. The results showed large intra- and inter-subject variances in the clearance times. Clearance times determined by the saccharin taste method were shorter than those determined by the dye method, but these measures were positively correlated. Also, the mean clearance rate was directly related to the mean nasal conductance. In seven of ten subjects, the clearance rate for a given side of the nasal passage was relatively faster when that side was the more patent. These results suggest that the clearance rate is a function of the patency of the nasal passage and may also exhibit alternating cyclic fluctuations.
在十个受试者中，于六个不同的测试日双侧测量鼻气道通畅度和鼻腔清除率。使用前鼻测压法评估鼻通畅度，并用染色糖精法测量清除率。结果显示，清除时间在受试者内和受试者间存在很大差异。糖精味觉法测定的清除时间比染料法测定的短，但这些测量结果呈正相关。此外，平均清除率与平均鼻导纳直接相关。在十名受试者中的七名中，当鼻腔通道的某一侧更通畅时，该侧的清除率相对较快。这些结果表明，清除率是鼻通道通畅度的函数，并且可能还会呈现交替的周期性波动。
