There are very few data available on the effects of respiratory protective masks on sleep. This study was to undertaken to investigate the effects of the M-40 protective mask on sleep architecture. We asked 21 healthy volunteers (18-35 yr) to participate in a two-night study. During the first night, subjects underwent standard polysomnography without the M40 mask. The second night entailed sleeping while wearing the mask, without the hood. Specific variables measured on each night included sleep stage distribution, time awake, number of awakenings, oxygen saturation, number of apneas and hypopneas, and time to sleep onset. Statistical analysis was performed using a two-tailed, paired t-test for all variables except REM sleep, for which a one-tailed, paired t-test was used. There was a significant difference between mask and non-mask nights when measuring total sleep time, total awake time, percentage of time in REM, and number of awakenings. It is concluded that sleep in the M40 mask is disrupted compared to sleep without the mask, with significant decreases in total sleep time and REM sleep.
关于呼吸防护口罩对睡眠影响的数据非常少。本研究旨在调查M - 40防护口罩对睡眠结构的影响。我们邀请了21名健康志愿者（18 - 35岁）参与一项为期两晚的研究。在第一晚，受试者在不佩戴M40口罩的情况下进行标准多导睡眠监测。第二晚则戴着口罩但不戴头罩入睡。每晚测量的特定变量包括睡眠阶段分布、清醒时间、觉醒次数、血氧饱和度、呼吸暂停和低通气次数以及入睡时间。除快速眼动睡眠（REM睡眠）外，所有变量均采用双尾配对t检验进行统计分析，对于REM睡眠采用单尾配对t检验。在测量总睡眠时间、总清醒时间、REM睡眠时间百分比和觉醒次数时，戴口罩和不戴口罩的夜晚之间存在显著差异。得出的结论是，与不戴口罩的睡眠相比，佩戴M40口罩时睡眠受到干扰，总睡眠时间和REM睡眠显著减少。
