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.
