A clinical study was undertaken to establish what changes in values were caused by the nozzle used in the Cottle flow-pressure technique of rhinomanometry. Cottle rhino-sphygmo-manometry was performed over seven hundred times, half with the nozzle and half without and the results analyzed using pattern, rate, amplitude, work co-efficient and four breath factor as outlined by Cottle. In many instances marked changes did occur but were unpredictable by examination prior to testing. It is suggested that Cottle rhino-sphygmo-manometry be carried out routinely with and without this nozzle in order to better evaluate results of flow-pressure relationship in which this nozzle is used.
开展了一项临床研究，以确定在鼻阻力测量的科特尔流量-压力技术中使用的喷嘴会导致数值发生哪些变化。进行了700多次科特尔鼻脉搏测量法，一半使用喷嘴，一半不使用喷嘴，并按照科特尔概述的模式、速率、幅度、工作系数和四呼吸因素对结果进行分析。在许多情况下确实发生了显著变化，但在测试前通过检查无法预测。建议常规进行使用和不使用该喷嘴的科特尔鼻脉搏测量法，以便更好地评估使用该喷嘴时的流量-压力关系结果。
