This study aimed to determine if the intensity of breathing noise (including snoring) and/or the presence of abnormal breathing events (ABE) are factors that trigger arousal/awakening of a snorer's bed partner.
We conducted a prospective multicenter study investigating couples where the male had a chronic disturbing snoring. We simultaneously recorded the male's respiration and snoring and the female' sleep. We counted the number of arousals and awakenings during N2 sleep and randomly took nine of each. Then, for periods before, during, and after each arousal and awakening, we observed on the respiratory tracings what was happening in terms of breathing noise intensity and presence/absence of snoring and/or ABE.
Thirteen couples were analyzed. The intensity of breathing noise and the presence/absence of snoring and/or ABE were comparable before and at initiation of arousal/awakening and between arousal and awakening. However, breathing volume intensity was lower and the presence of snoring and/or ABE was less frequent when the bed partner returned back to sleep from awakening compared to the other periods (p always <0.001).
The intensity of breathing noise or the presence of ABE does not seem to be essential to trigger an arousal or an awakening. However, the persistence of noise or events may prolong the duration of wakefulness during the sleep period and could be one factor that explains the bothersome snoring.
本研究旨在确定呼吸噪声（包括打鼾）的强度和/或异常呼吸事件（ABE）的存在是否是打鼾者的枕边人觉醒/唤醒的触发因素。
我们进行了一项前瞻性多中心研究，调查了男性患有慢性烦人的打鼾的夫妇。我们同时记录了男性的呼吸和打鼾以及女性的睡眠。我们计算了 N2 睡眠期间的觉醒和唤醒次数，并随机抽取了每一种的 9 次。然后，在每次觉醒和唤醒前后的时间段内，我们观察呼吸记录上的呼吸噪声强度以及打鼾和/或 ABE 的存在/缺失情况。
分析了 13 对夫妇。在觉醒/唤醒开始之前和期间，呼吸噪声的强度以及打鼾和/或 ABE 的存在/缺失情况与觉醒和唤醒之间没有差异。然而，与其他时间段相比，当枕边人从唤醒状态重新入睡时，呼吸音量强度较低，且打鼾和/或 ABE 的出现频率较低（p 始终<0.001）。
呼吸噪声的强度或 ABE 的存在似乎不是触发觉醒或唤醒的必要条件。然而，噪声或事件的持续存在可能会延长睡眠期间的清醒时间，这可能是解释烦人的打鼾的一个因素。
