The influence of sleep states on the metabolic rate and on the respiratory quotient (RQ) of low-birth-weight infants during continuous feeding was analyzed. Gestational age at birth varied between 29 and 35 weeks, postnatal age between 2 and 56 days and body weight between 0.81 and 2.11 kg. The mean oxygen consumption and carbon dioxide production were 10% higher, while the rise in SD was about 3-fold during REM sleep compared with NREM sleep. The RQ, however, was equal in both states. The sequence of the two sleep states did not have any influence on the analyzed parameters. Averaged over all the measurements, no statistically significant linear trend in oxygen consumption as a function of time could be found. However, small non-zero trends could be found, the direction of which appeared to depend on the sequence of the states.
分析了睡眠状态对低体重儿持续喂养期间代谢率和呼吸商（RQ）的影响。出生时的胎龄在29至35周之间，出生后年龄在2至56天之间，体重在0.81至2.11千克之间。与非快速眼动睡眠相比，快速眼动睡眠期间平均耗氧量和二氧化碳产生量高10%，而标准差的增加约为3倍。然而，两种睡眠状态下的呼吸商相等。两种睡眠状态的顺序对所分析的参数没有任何影响。在所有测量值上进行平均，未发现耗氧量随时间变化的具有统计学意义的线性趋势。然而，可以发现小的非零趋势，其方向似乎取决于睡眠状态的顺序。
