Pneumotachographic recording of ventilation requires an air-tight nasobuccal face-mask which might disturb the subjects' sleep and thereby modify their breathing pattern. In a cross-over randomised study we compared recordings obtained with and without a face-mask in 20 healthy normal volunteers (10 males, 10 females, mean age = 21.7 +/- S.E.M. = 0.5). The sleep modifications that resulted from the presence of the face-mask were a lengthening of the REM-sleep latency (+ 38%; P less than 0.01), an increase in intra-sleep waking-time (+ 65%, P less than 0.05), an increase in stage I duration (+ 40%, P less than 0.02), and a decrease in REM-sleep duration (- 20%, P less than 0.01), resulting in a decrease in total sleep duration (- 9%, P less than 0.05). The sleep latency, the number of awakenings, the stage II duration, the deep slow-wave sleep duration, the sleep stability, and the number of sleep cycles were not significantly modified.
使用呼吸速度描记法记录通气情况需要一个密封的鼻颊面罩，这可能会干扰受试者的睡眠，从而改变他们的呼吸模式。在一项交叉随机研究中，我们比较了20名健康正常志愿者（10名男性，10名女性，平均年龄 = 21.7 +/- 标准误 = 0.5）在使用和不使用面罩情况下获得的记录。面罩的存在导致的睡眠改变包括快速眼动睡眠潜伏期延长（+ 38%；P < 0.01）、睡眠中觉醒时间增加（+ 65%，P < 0.05）、I期睡眠时间增加（+ 40%，P < 0.02）以及快速眼动睡眠时间减少（- 20%，P < 0.01），从而导致总睡眠时间减少（- 9%，P < 0.05）。睡眠潜伏期、觉醒次数、II期睡眠时间、深慢波睡眠时间、睡眠稳定性和睡眠周期数没有显著改变。
