Fetal pulse oximetry. Instrumentation and recent clinical experience.
Despite the pressing clinical need to improve fetal intrapartum surveillance, fetal oximetry has lagged well behind its application in the neonate because of the difficulty of developing a suitable method to record data from the fetus and testing its accuracy and reproducibility. Acceptable values of oxygen saturation that indicate fetal well-being are much lower than in neonates. The development of fetal pulse oximetry instrumentation is discussed. Recent clinical data acquired using the latest instrumentation are summarized and exciting new clinical applications proposed.
