Arterio-venous differences in acid-base parameters of umbilical vessels blood using Nickelsen and Weber method and SPSS/PC+ computer's program were calculated. The mean differences are dependent on fetal metabolism, umbilical blood flow and placental gas exchange. Arterio-venous differences--normal or increased for pH, PCO2, PO2 and SO2 are valuable diagnostic indicators of accurate gas exchange while decreased values of these differences should predict placental dysfunction. Small differences are signs of chronic fetus hypoxaemia originated by anaerobic metabolism and increased the fetal lactic acid production, respectively.
采用尼克elsen和韦伯方法以及SPSS/PC +计算机程序计算脐血管血酸碱参数的动静脉差异。平均差异取决于胎儿代谢、脐血流量和胎盘气体交换。动静脉差异（pH、PCO2、PO2和SO2正常或升高）是准确气体交换的重要诊断指标，而这些差异值降低则预示胎盘功能障碍。差异小是无氧代谢引起的慢性胎儿低氧血症的征象，分别增加了胎儿乳酸的产生。
