本研究的目的是评估与睡眠呼吸障碍夜间变异相关的因素。 在这项研究中，对 71 名患有不同程度睡眠呼吸暂停的老年志愿者连续两个实验室夜晚的睡眠呼吸障碍的变异性进行了评估。 高变异性 (n = 13) 和低变异性 (n = 58) 组是根据每小时至少十个事件的绝对两晚呼吸暂停/呼吸不足指数差异而形成的。 结果表明，高变异性与较长的软腭测量值和体检时是否存在鼻塞有关。 在高变异性组中，在两个晚上相同的总体体位下，睡眠呼吸障碍的变化发生了。 结果表明，影响气道通畅的局部解剖因素可能并非每晚都是恒定的。
The purpose of this study was to evaluate factors associated with nightly variability in sleep-disordered breathing. In this study, variability in sleep-disordered breathing over two consecutive laboratory nights was evaluated in 71 aged volunteers with varying levels of sleep apnea. High variability (n = 13) and low variability (n = 58) groups were formed on the basis of an absolute two-night apnea/hypopnea index difference of a minimum ten events per hour. Results indicate high variability was related to longer soft palate measurements and the presence of nasal obstruction on physical examination. Within the high variability group, variation in sleep-disordered breathing occurred within identical gross body position over the two nights. The results suggest that local, anatomic factors affecting airway patency may not be constant from night to night.
