使用脉搏血氧仪测量血氧饱和度是一种在分娩期间连续监测人类胎儿健康状况的既定方法。在兽医学中，脉搏血氧饱和度测定法几乎专门用于重症监护和麻醉学。本研究的目的是调查牛胎儿在分娩的第11阶段的氧饱和度的生理变化，并确定是否可以用来预测产后酸中毒的研究结果。对23头新生犊牛的脉搏血氧饱和度（SpO（2））与动脉血氧饱和度（SaO（2））进行了相关性研究。此外，通过脉搏血氧饱和度（FSpO（2））连续监测33头牛胎儿在分娩第二阶段的氧饱和度。测定了分娩第二阶段最后30分钟和5分钟的FSpO（2）值与产后动脉血pH值、氧分压、二氧化碳分压、碳酸氢盐浓度、BE、SaO（2）和乳酸浓度的相关性。产后SpO（2）与SaO（2）高度相关（r = 0.923）。FSpO（2）值与pH和BE中度相关，与产后乳酸浓度弱相关; pH < 7.2、BE < -3 mM/L或乳酸浓度>5.4 mM/L的小牛的FSpO（2）值显著低于非酸中毒小牛。FSpO（2）值
Measurement of oxygen saturation using pulse oximetry is an established method of continuous monitoring of the well-being of the human fetus during parturition. In veterinary medicine, pulse oximetry has been used almost exclusively in intensive care and anesthesiology. The goal of the present study was to investigate the physiological changes in oxygen saturation of the bovine fetus during stage 11 of parturition and to determine whether the findings can be used to predict postnatal acidosis. The correlation between the oxygen saturation (SpO(2)) measured via pulse oximetry and the oxygen saturation (SaO(2)) of arterial blood measured via blood gas analysis was determined in 23 newborn calves. In addition, the oxygen saturation was monitored continuously via pulse oximetry (FSpO(2)) in 33 bovine fetuses during stage II of parturition. Correlations between the FSpO(2) values during the last 30 and 5 min of stage II of parturition and the postpartum values for pH, partial pressures of oxygen and carbon dioxide, bicarbonate concentration, BE, SaO(2) and lactate concentration in arterial blood were determined. There was a high correlation between SpO(2) and SaO(2) postpartum (r = 0.923). The FSpO(2) values correlated moderately with the pH and BE and weakly with the lactate concentration postpartum; calves with a pH < 7.2, a BE < -3 mM/L or a lactate concentration of >5.4 mM/L had significantly lower FSpO(2) values than non-acidotic calves. FSpO(2) values
