title: Intrapartum fetal pulse oximetry and fetal heart rate decelerations.
abstract: OBJECTIVE
  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.
