OBJECTIVE
: The nasal cycle, which is present in a significant number of people, is an ultradian side-to-side rhythm of nasal engorgement associated with cyclic autonomic activity. We studied the nasal cycle during REM/non-REM sleep stages and examined the potentially confounding influence of body position on lateralized nasal airflow.
METHODS
: Left- and right-side nasal airflow was measured in six subjects during an eight-hour sleep period using nasal thermistors. Polysomnography was performed. Simultaneously, body positions were monitored using a video camera in conjunction with infrared lighting.
RESULTS
: Significantly greater airflow occurred through the right nasal chamber (relative to the left) during periods of REM sleep than during periods of non-REM sleep (p<0.001). Both body position (p < 0.001) and sleep stage (p < 0.001) influenced nasal airflow lateralization.
CONCLUSIONS
: This study demonstrates that the lateralization of nasal airflow and sleep stage are related. Some types of asymmetrical somatosensory stimulation can alter this relationship.
目的
鼻周期存在于大量人群中，是一种与周期性自主神经活动相关的鼻腔充血的超日节律性左右交替变化。我们研究了快速眼动（REM）/非快速眼动睡眠阶段的鼻周期，并考察了体位对鼻腔气流侧化的潜在混杂影响。
方法
在6名受试者8小时的睡眠期间，使用鼻热敏电阻测量左右鼻腔的气流。进行多导睡眠监测。同时，使用摄像机结合红外照明监测体位。
结果
与非快速眼动睡眠期相比，快速眼动睡眠期右侧鼻腔（相对于左侧）的气流明显更大（p<0.001）。体位（p<0.001）和睡眠阶段（p<0.001）均影响鼻腔气流侧化。
结论
本研究表明鼻腔气流侧化与睡眠阶段有关。某些类型的不对称体感刺激可改变这种关系。
