Although polysomnography is routinely performed to evaluate children and adolescents with sleep-disordered breathing, normal polysomnographic values for the pediatric age group have not yet been established. We therefore performed overnight polysomnography in 50 normal children and adolescents (mean age 9.7 +/- 4.6 SD yr, range 1.1 to 17.4 yr). Of the children 56% were male. Chest wall motion, ECG, oronasal airflow, end-tidal PCO2 (PETCO2), arterial oxygen saturation (SaO2), and electrooculogram were monitored. Children had 0.1 +/- 0.5 (range 0 to 3.1) obstructive apneas per hour of total sleep time, with only 18% of children having any obstructive apneas. No child had obstructive apneas > 10 s in duration. Of the children 30% had central apneas > or = 10 s in duration, and one child had a central apnea associated with SaO2 < 90%. Peak PETCO2 was 46 +/- 4 mm Hg (range 38 to 53 mm Hg), and hypoventilation (PETCO2 > 45 mm Hg) occurred for 7 +/- 19% total sleep time (range 0 to 91%). The SaO2 nadir was 96 +/- 2% (range 89 to 98%), with only one child desaturating below 90% in association with a central apnea. We conclude that polysomnographic results in the pediatric age group differ from those in adults. Recommendations for normal polysomnographic criteria are given.
尽管多导睡眠图常用于评估患有睡眠呼吸障碍的儿童和青少年，但尚未确立该年龄段儿童多导睡眠图的正常参考值。因此，我们对50名正常儿童和青少年（平均年龄9.7±4.6标准差岁，范围1.1至17.4岁）进行了整夜多导睡眠图检查。其中56%为男性。监测了胸壁运动、心电图、口鼻气流、呼气末二氧化碳分压（PETCO2）、动脉血氧饱和度（SaO2）和眼电图。儿童每小时总睡眠时间的阻塞性呼吸暂停次数为0.1±0.5次（范围0至3.1次），只有18%的儿童有任何阻塞性呼吸暂停。没有儿童的阻塞性呼吸暂停持续时间超过10秒。30%的儿童有持续时间≥10秒的中枢性呼吸暂停，1名儿童的中枢性呼吸暂停伴有SaO2<90%。PETCO2峰值为46±4毫米汞柱（范围38至53毫米汞柱），通气不足（PETCO2>45毫米汞柱）占总睡眠时间的7±19%（范围0至91%）。SaO2最低点为96±2%（范围89至98%），只有1名儿童在中枢性呼吸暂停时血氧饱和度降至90%以下。我们得出结论，儿童年龄段的多导睡眠图结果与成人不同。给出了多导睡眠图正常标准的建议。
