Abstract

Nasal obstruction requires close attention, as it is a risk factor for obstructive sleep apnea (OSA). This study evaluated airflow rates of our newly designed nasal breathing stent (NBS) compared with those of existing nasal dilators in 10 adult men. We hypothesized that the NBS would expand the nasal passage more than the other nasal dilators by means of airflow measurements. We compared airflow measurements between the NBS and three existing appliances and no appliance. Velocity measurements were recorded by analyzing 499 videographic images when each appliance was placed next to a steam generator at 0, 5, and 10 mm from the outlet port for airflow visualization. The peak nasal inspiratory flow (PNIF) rate was measured using an inspiratory flow meter. The NBS resulted in significantly higher airflow velocity measurements at all distances from the outlet port and a higher PNIF rate than the other appliances. Thus, the NBS offers a significantly decreased resistance to air movement compared with other appliances. Future in-depth investigations are required to demonstrate the use of NBS as a nasal dilator in conjunction with continuous positive airway pressure/oral appliance treatments in patients with OSA.
一种新型鼻腔呼吸支架改善鼻腔气流
鼻塞需要密切关注,因为它是阻塞性睡眠呼吸暂停(OSA)的危险因素。本研究评估了我们新设计的鼻呼吸支架(NBS)与现有鼻扩张器的气流速率。通过气流测量,我们假设NBS比其他鼻扩张器更能扩大鼻通道。我们比较了NBS和三个现有器具和没有器具之间的气流测量。速度测量是通过分析499个视频图像来记录的,当每个器具被放置在离出口0、5和10毫米的蒸汽发生器旁边,以显示气流。采用吸气流量计测量鼻吸流量峰值(PNIF)率。NBS导致在离出口所有距离上的气流速度测量值明显高于其他设备,PNIF率也高于其他设备。因此,与其他电器相比,NBS提供了显着降低的空气运动阻力。未来的深入研究需要证明NBS作为鼻扩张器与持续气道正压/口腔器械治疗在OSA患者中的应用。
