Three adult patients with asthma with preferential nasal breathing were found to have a typical pattern of lung function test results with substantial between test variation. This condition can be identified as a cause of unsatisfactory performance in respiratory tests by observing the patient's reaction after the nostrils have been occluded.
三名有优先经鼻呼吸的成年哮喘患者被发现具有典型的肺功能测试结果模式，测试之间存在显著差异。通过观察患者在鼻孔被阻塞后的反应，这种情况可被确定为呼吸测试表现不佳的一个原因。
