虽然多导睡眠描记仪常规用于评估患有睡眠呼吸障碍的儿童和青少年，但儿童年龄组的正常多导睡眠描记值尚未确定。因此，我们对50名正常儿童和青少年（平均年龄9.7 ± 4.6 SD岁，范围1.1至17.4岁）进行了夜间多导睡眠图检查。56%的儿童是男孩。监测胸壁运动、ECG、口鼻气流、呼气末二氧化碳分压（PET（CO2））、动脉血氧饱和度（Sa（O2））和眼电图。儿童每小时总睡眠时间有0.1 +/- 0.5（范围0至3.1）阻塞性呼吸暂停，只有18%的儿童有任何阻塞性呼吸暂停。无儿童阻塞性呼吸暂停持续时间> 10 s。30%的儿童中枢性呼吸暂停持续时间大于或等于10 s，1名儿童中枢性呼吸暂停与Sa（O2）<90%相关。峰值PET（CO2）为46 +/- 4 mm Hg（范围38 - 53 mm Hg），通气不足（PET（CO2）> 45 mm Hg）发生在7 +/- 19%的总睡眠时间（范围0 - 91%）。Sa（O2）最低值为96 +/-2%（范围89 - 98%），只有1例患儿血氧饱和度下降至90%以下，并伴有中枢性呼吸暂停。我们的结论是，多导睡眠图的结果在儿童年龄组不同于成人。给出了正常多导睡眠图标准的建议。
Although polysomnography is routinely performed to evaluate children and adolescents cents 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 (PET(CO2)), arterial oxygen saturation (Sa(O2)), 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 greater-than-or-equal-to 10 s in duration, and one child had a central apnea associated with Sa(O2) < 90%. Peak PET(CO2) was 46 +/- 4 mm Hg (range 38 to 53 mm Hg), and hypoventilation (PET(CO2) > 45 mm Hg) occurred for 7 +/- 19% total sleep time (range 0 to 91%). The Sa(O2) 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.
