OBJECTIVES
To determine the behavior of fetal oxygenation (FSpO(2)) in different patterns of fetal heart rate decelerations (FHR).
METHODS
A total of 787 decelerations were studied.
RESULTS
FSpO(2) decreased significantly during decelerations, especially when the alteration was prolonged.
CONCLUSIONS
Modifications in FHR occur simultaneously with alterations in FSpO(2), although the latter do not persist in time. Different degrees of FSpO(2) seen prior to deceleration are an expression of fetal respiratory status.
目的
确定胎儿心率减速（FHR）不同模式下胎儿氧合（FSpO₂）的变化情况。
方法
共研究了787次减速。
结果
减速期间FSpO₂显著下降，尤其是当变化持续时间较长时。
结论
FHR的变化与FSpO₂的变化同时发生，尽管后者不会持续很长时间。减速前观察到的不同程度的FSpO₂是胎儿呼吸状态的一种表现。
