Examination of paired umbilical arterial and umbilical venous blood gases for 147 term, healthy newborns revealed a strong correlation of pH, bicarbonate, and base excess with the 1-minute Apgar score. Although significantly different from each other, a strong correlation existed between the gas measurements of the two vessels. The lower limit of pH for the umbilical artery was 7.12 and for the vein, 7.25. The arterial-venous difference for bicarbonate but not pH, oxygen or carbon dioxide tension, or base excess was correlated with the 1-minute Apgar score.
对147名足月儿、健康新生儿的脐动脉血和脐静脉血进行血气分析，结果显示pH值、碳酸氢盐和碱剩余与1分钟阿氏评分之间存在强相关性。尽管两条血管的血气测量值存在显著差异，但二者之间仍存在强相关性。脐动脉血pH值的下限为7.12，脐静脉血pH值的下限为7.25。碳酸氢盐的动静脉差值与1分钟阿氏评分相关，而pH值、氧分压、二氧化碳分压或碱剩余的动静脉差值与1分钟阿氏评分无关。
