In an attempt to detect the influence of various kinds of face masks and a nasal nozzle on nasal airflow, we made measurements of nasal resistance by a head-out body plethysmograph with or without the masks on the face or the nozzle to the nostril of the normal adult subjects. The mean values of nasal resistance with the masks differed from the mean values without the masks significantly. No significant difference between values with and without the nozzle was found. The coefficient variations of 40 consecutive measurements of nasal resistance with the masks or the nozzle had wider ranges than those without the apparatuses. But the variation due to the nozzle was the minimum in the apparatuses.
为了检测各种口罩和鼻夹对鼻气流的影响，我们使用头出式体容积描记仪，对正常成年受试者面部佩戴或不佩戴口罩以及鼻孔佩戴或不佩戴鼻夹时的鼻阻力进行了测量。佩戴口罩时的鼻阻力平均值与不佩戴口罩时的平均值有显著差异。佩戴和不佩戴鼻夹时的值之间未发现显著差异。使用口罩或鼻夹连续40次测量鼻阻力的系数变化范围比不使用这些装置时更宽。但在这些装置中，鼻夹引起的变化最小。
