Oxygen consumption was measured in 9 short-gestation infants before feeding and for an hour after, using a closed-circuit metabolism chamber. Using the same system, O2 consumption of 9 term infants was measured for varying periods, beginning one hour from the end of the last feed. In the short-gestation infants a rise was found in the 15--45 minutes after feeding; O2 consumption then fell, and after 60 minutes had reached prefeed levels. The term infants showed no decrease with time after the first hour, as would be expected if the effect of feeding on O2 consumption extended beyond this. It is concluded that increased O2 demand after appropriate feeding does not extend beyond one hour postprandially.
使用闭路代谢室，对9名早产婴儿在喂食前及喂食后1小时的耗氧量进行了测量。使用同一系统，对9名足月儿在最后一次喂食结束1小时后开始的不同时间段内的耗氧量进行了测量。在早产婴儿中，发现喂食后15 - 45分钟耗氧量上升；随后耗氧量下降，60分钟后已降至喂食前水平。足月儿在第一小时后未随时间出现下降，而如果喂食对耗氧量的影响超出此范围，情况则会相反。结论是，适当喂食后增加的氧气需求不会超过餐后1小时。
