Patients suspected to have sleep-disordered breathing underwent an overnight polysomnography using a divided nasal cannula to gain additional information about the nasal cycle during sleep.
This was a prospective, observational cohort study replacing the undivided nasal cannula with a divided nasal cannula during routine polysomnography (n = 28).
Integration of the divided nasal cannula pressure transducer system into routine polysomnography was easy and affordable. Most patients (89%) demonstrated nasal cycle changes during the test. Nasal cycle changes tended to occur during body position changes (62%) and transitions from non-rapid eye movement sleep to rapid eye movement sleep (41%). The mean nasal cycle duration was 2.5 ± 2.1 hours. Other sleep study metrics did not reveal statistically significant findings in relation to the nasal cycle.
Replacing an undivided nasal cannula with a divided nasal cannula is easy to implement, adding another physiologic measure to polysomnography. Although the divided nasal cannula did not significantly affect traditional polysomnographic metrics such as the apnea-hypopnea index or periodic limb movement index based on this small pilot study, we were able to replicate past nasal cycle findings that may be of interest to sleep clinicians and researchers. Given the ease with which the divided nasal cannula can be integrated, we encourage other sleep researchers to investigate the utility of using a divided nasal cannula during polysomnography.
怀疑患有睡眠呼吸障碍的患者接受了整夜多导睡眠图检查，使用分开的鼻导管以获取更多关于睡眠期间鼻周期的信息。
这是一项前瞻性观察队列研究，在常规多导睡眠图检查中用分开的鼻导管代替未分开的鼻导管（n=28）。
将分开的鼻导管压力换能器系统集成到常规多导睡眠图中很容易且经济实惠。大多数患者（89%）在测试中表现出鼻周期变化。鼻周期变化倾向于在体位变化时（62%）和非快速眼动睡眠向快速眼动睡眠过渡时（41%）发生。平均鼻周期持续时间为 2.5±2.1 小时。其他睡眠研究指标与鼻周期无统计学显著相关性。
用分开的鼻导管代替未分开的鼻导管易于实施，为多导睡眠图增加了另一种生理测量方法。尽管根据这项小型试点研究，分开的鼻导管并未显著影响传统的多导睡眠图指标，如呼吸暂停-低通气指数或周期性肢体运动指数，但我们能够复制过去的鼻周期发现，这些发现可能引起睡眠临床医生和研究人员的兴趣。鉴于分开的鼻导管易于集成，我们鼓励其他睡眠研究人员研究在多导睡眠图检查期间使用分开的鼻导管的效用。
