The pediatric pneumogram is a frequently used tool in the diagnosis and management of apnea during infancy. We analyzed 287 pneumographic recordings from 123 full-term infants (63 males) obtained during the first 12 months of life to establish normative values for apnea, periodic breathing, and bradycardia. The results of the analysis were compared by sex and age. The number of infants who exhibited periodic breathing decreased significantly over time (78% at 0-2 weeks vs 29% at 39-52 weeks; P less than 0.05). However, for those infants who did breathe periodically, the percent of sleep time spent in this breathing pattern did not change with age. No apnea greater than or equal to 15 seconds was recorded in any infant, and apnea density (total apnea greater than or equal to 10 seconds in minutes/100 minutes sleep time) did not change with age or sex. Using our definitions, no bradycardia was identified. Normal full-term infants occasionally have apnea of 10, 11, or 12 seconds, and, until 6 months of age, the majority will have a small amount of periodic breathing (less than 1% of sleep time) during sleep at home.
小儿呼吸描记图是诊断和处理婴儿期呼吸暂停的常用工具。我们分析了123名足月儿（63名男性）在出生后12个月内获得的287份呼吸描记图记录，以确定呼吸暂停、周期性呼吸和心动过缓的正常值。分析结果按性别和年龄进行比较。出现周期性呼吸的婴儿数量随时间显著减少（0 - 2周时为78%，39 - 52周时为29%；P小于0.05）。然而，对于那些确实有周期性呼吸的婴儿，这种呼吸模式所占用的睡眠时间百分比并未随年龄变化。在任何婴儿中均未记录到持续时间大于或等于15秒的呼吸暂停，呼吸暂停密度（每分钟内持续时间大于或等于10秒的总呼吸暂停时间/100分钟睡眠时间）也未随年龄或性别而变化。按照我们的定义，未发现心动过缓。正常足月儿偶尔会出现10、11或12秒的呼吸暂停，并且在6个月龄之前，大多数婴儿在家中睡眠时会有少量的周期性呼吸（占睡眠时间的比例小于1%）。
