During their spontaneous recovery after birth, the acid-base balance was studied in 32 healthy newborns. The observation period lasted for 4 hours. Determinations were carried out, both in umbilical vessels as in central arterial blood. The most outstanding phenomenon was an increase in acidosis at 30 minutes of life. The metabolic component predominating over the respiratory was a definitely evident fact. At the end of four hours, the acid-base balance reached figures considered normal for the adult.
在32名健康新生儿出生后的自然恢复过程中，对其酸碱平衡进行了研究。观察期持续4小时。在脐血管和中心动脉血中均进行了测定。最显著的现象是出生30分钟时酸中毒增加。代谢成分比呼吸成分占优势这一事实确凿无疑。4小时结束时，酸碱平衡达到了成年人的正常数值。
