Twenty-four children suspected of having apnea induced by lymphoid pharyngeal obstruction were studied by nocturnal polygraphy. The data recorded were: instantaneous cardiac frequency, thoracic movements, naso-oral flux, transcutaneous PO2 and PCO2. Episodes of hypoxemia and of hypercapnia related to obstructive apneas were found in 19 children; the mean of the lowest values of PtcO2 during sleep was 58.4 mmHg versus 85 mmHg during wakefulness. The mean od the highest values of PtcCO2 was 50 mmHg during sleep versus 40 mmHg during wakefulness. Six children presented with marked hypoxemia (PtcO2 less than or equal to 50 mmHg). Transcutaneous blood gas monitoring is indicated in all children presenting with sleep disorders due to pharyngeal obstruction. The finding of a marked hypoxemia should suggest removal of the obstacle concerned.
对24名疑似因咽部淋巴组织阻塞导致呼吸暂停的儿童进行了夜间多导睡眠监测研究。记录的数据包括：瞬时心率、胸廓运动、鼻口气流、经皮血氧分压（PO2）和二氧化碳分压（PCO2）。在19名儿童中发现了与阻塞性呼吸暂停相关的低氧血症和高碳酸血症发作；睡眠期间经皮血氧分压（PtcO2）最低值的平均值为58.4 mmHg，而清醒时为85 mmHg。睡眠期间经皮二氧化碳分压（PtcCO2）最高值的平均值为50 mmHg，而清醒时为40 mmHg。6名儿童出现明显低氧血症（PtcO2小于或等于50 mmHg）。对于所有因咽部阻塞导致睡眠障碍的儿童，均建议进行经皮血气监测。发现明显低氧血症时应考虑去除相关阻塞物。
