TI  - Respiration and heart rate variation in normal infants during quiet sleep in the 
      first year of life.

AB  - 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.
