The stability of blood gas and acid-base values in bovine venous blood samples (n = 22) stored on ice for 3, 6, 9, or 24 hours was studied. Values studied include pH, PO2 and PCO2 tensions, base excess, standard base excess, bicarbonate concentration, standard bicarbonate concentration, total carbon dioxide content, oxygen saturation, and hemoglobin. The results indicate that, except for PCO2, changes in blood gas and acid-base values during 24 hours of storage and differences between cattle of differing ages, rectal temperatures, and acid-base status were too small to be of clinical significance. Therefore, bovine venous blood samples stored up to 24 hours on ice are of diagnostic utility.
研究了22份牛静脉血样本在冰上储存3、6、9或24小时后血气和酸碱值的稳定性。所研究的值包括pH值、PO2和PCO2张力、碱剩余、标准碱剩余、碳酸氢盐浓度、标准碳酸氢盐浓度、总二氧化碳含量、氧饱和度和血红蛋白。结果表明，除PCO2外，储存24小时期间血气和酸碱值的变化以及不同年龄、直肠温度和酸碱状态的牛之间的差异太小，无临床意义。因此，在冰上储存长达24小时的牛静脉血样本具有诊断价值。
