Abstract
  1. Ventilation was recorded in thirty term infants during the first week after delivery using the trunk plethysmograph, during periods of rapid eye movement sleep (r.e.m.) and quiet sleep (n.r.e.m.). 2. Continuous histograms of tidal volume (VT) and instantaneous respiration rate (f) were samples at 0.5 sec intervals, passed through a digital filter to remove long-term trends in the data, and then subjected to frequency analysis. 3. In all the infants oscillations in VT and f were detected, with mean periods varying from 6.7 to 12.5 sec. The amplitude of these oscillations was higher during r.e.m. than n.r.e.m. sleep in all the infants. 4. The oscillations in VT tended to be out of phase with those for f, particularly during n.r.e.m. sleep; this contrasted with in-phase oscillations in VT and f found during periodic breathing in an additional six premature infants studied.
摘要
  1. 在出生后的第一周内,使用躯干体积描记器对30名足月儿在快速眼动睡眠(r.e.m.)和安静睡眠(n.r.e.m.)期间的通气情况进行了记录。2. 以0.5秒的间隔对潮气量(VT)和瞬时呼吸频率(f)的连续直方图进行采样,通过数字滤波器去除数据中的长期趋势,然后进行频率分析。3. 在所有婴儿中均检测到VT和f的振荡,平均周期从6.7秒到12.5秒不等。在所有婴儿中,这些振荡的幅度在r.e.m.睡眠期间高于n.r.e.m.睡眠期间。4. VT的振荡往往与f的振荡不同相,尤其是在n.r.e.m.睡眠期间;这与另外6名研究的早产儿在周期性呼吸期间发现的VT和f的同相振荡形成对比。
