The lateral wall of the nostril is considered as the functional unit in the regulation of the nasal resistance causing more than half of the total resistance. In 16 test-subjects both nostrils were dilated with a plastic nasal device, Nozovent, and the airflow through the nose was measured with and without the device. In each object the mean value of ten inspirations at 150 Pa was calculated. Before the application the mean value of the subjects was 0.68 l/sec and with the device 0.84 l/sec. The improvement of airflow was comparable with that of treatment with nose-drops. The device ought to be helpful in patients with or without collapsing ala nasi during the night to increase nasal airflow when sleeping.
鼻孔侧壁被视为调节鼻阻力的功能单位，其产生的阻力占总阻力的一半以上。在16名受试者中，使用一种名为Nozovent的塑料鼻装置扩张双侧鼻孔，并测量使用该装置前后通过鼻腔的气流。在每个受试者中，计算在150帕压力下十次吸气的平均值。使用该装置前受试者的平均值为0.68升/秒，使用后为0.84升/秒。气流的改善与滴鼻剂治疗相当。该装置对于夜间有无鼻翼塌陷的患者应该都有帮助，可在睡眠时增加鼻腔气流。
