Forty-three all-night sleep recordings have been performed on 19 control infants of the ages 6 weeks, 6 months and 1 year. During eight hour periods 22 physiological parameters were sampled by a personal computer based monitoring system and stored on an optical disk. This paper reports on spectral analysis of breathing and heart rate patterns during the first and last episode of quiet sleep at three different age groups. The results demonstrate that the respiratory rate during quiet sleep decreases (6 weeks: 37.2 +/- 5.4; 6 months: 30.1 +/- 4.9; 1 year: 24.1 +/- 1.8; adults (mean age 25.1 +/- 2.8 years; n = 10): 14.8 +/- 1.8; values are means +/- one standard deviation in breaths/min) and the respiratory coefficient Pm/Ps (higher values of Pm/Ps indicate lower respiratory variability) increases with age (6 weeks: 2.3 +/- 0.7; 6 months: 3.2 +/- 1.1; 1 year: 3.4 +/- 1.0; adults: 4.5 +/- 1.0). The calculation of the heart rate in beats per minute (bpm) and heart rate variability (%) revealed the following results: 6 weeks: 127.4 +/- 11.5 bpm, 3.8 +/- 1.5%; 6 months: 119.4 +/- 17.3 bpm, 4.2 +/- 1.7%; 1 year: 110.3 +/- 21.5 bpm, 5.8 +/- 2.3%; adults: 59.2 +/- 8.5 bpm, 4.3 +/- 2.2%. A comparison of the cardiorespiratory data from the first and last quiet sleep period showed no significant differences within either age group.
对19名年龄分别为6周、6个月和1岁的对照婴儿进行了43次全夜睡眠记录。在8小时时间段内，通过基于个人计算机的监测系统对22个生理参数进行采样，并存储在光盘上。本文报告了三个不同年龄组安静睡眠的第一阶段和最后阶段呼吸和心率模式的频谱分析结果。结果表明，安静睡眠期间的呼吸频率下降（6周：37.2±5.4；6个月：30.1±4.9；1岁：24.1±1.8；成年人（平均年龄25.1±2.8岁；n = 10）：14.8±1.8；数值为平均值±呼吸频率每分钟的一个标准差），呼吸系数Pm/Ps（Pm/Ps值越高表明呼吸变异性越低）随年龄增加（6周：2.3±0.7；6个月：3.2±1.1；1岁：3.4±1.0；成年人：4.5±1.0）。每分钟心跳次数（bpm）和心率变异性（%）的心率计算结果如下：6周：127.4±11.5 bpm，3.8±1.5%；6个月：119.4±17.3 bpm，4.2±1.7%；1岁：110.3±21.5 bpm，5.8±2.3%；成年人：59.2±8.5 bpm，4.3±2.2%。对第一个和最后一个安静睡眠期的心肺数据进行比较，发现在任何一个年龄组内均无显著差异。
