定义
这些疾病的主要特征是睡眠相关通气不足，导致睡眠期间动脉血二氧化碳分压（PaCO2）异常升高。当夜间监测发现成人血氧饱和度持续（> 5 分钟）下降至≤ 88%（或儿童≤ 90%）且持续时间≥ 5 分钟时，即可诊断为睡眠相关性低氧血症。 注：明确诊断需要基于多导睡眠呼吸监测以及睡眠期间二氧化碳（CO2）监测（通过动脉、呼气末或经皮测量）的客观证据。
The primary feature of these disorders is insufficient sleep related ventilation, resulting in abnormally elevated arterial partial pressure of carbon dioxide (PaCO2) during sleep. Sleep-related hypoxemia is diagnosed when overnight monitoring reveals sustained (> 5 minutes) decline in oxygen saturation to ≤ 88% in adults (or ≤ 90% in children) for ≥ 5 minutes. Note: A definitive diagnosis requires objective evidence based on polysomnography as well as carbon dioxide (CO2) monitoring during sleep (by arterial, end-tidal or transcutaneous measures).
