The effect of nose breathing on the systolic blood pressure was examined in ten healthy men. Nose breathing was increased above normal by exercise and tested by maximum bicycle ergometry. When the anterior part of the nose was dilated with Nozovent the nasal airflow increased by on average 29%. In this condition, all ten men could cycle at maximum load without mouth breathing and there was a significantly lower increase (13 mmHg) in the systolic blood pressure than when the nasal dilator was not used. The reason for this lower blood pressure increase is unknown. The hypothesis is put forward, however, that facilitated nose breathing decreases the respiratory work, which in turn lowers the systolic blood pressure during exercise.
在10名健康男性中研究了鼻呼吸对收缩压的影响。通过运动使鼻呼吸超过正常水平，并通过最大负荷自行车测力计进行测试。当使用诺佐文扩张鼻前部时，鼻气流平均增加29%。在这种情况下，所有10名男性都能在最大负荷下骑车而无需张口呼吸，并且收缩压的升高（13 mmHg）明显低于未使用鼻扩张器时。收缩压升高幅度较低的原因尚不清楚。然而，有人提出这样的假说，即顺畅的鼻呼吸减少了呼吸功，进而降低了运动期间的收缩压。
