The future of intrapartum fetal pulse oximetry

Fetal pulse oximetry has undergone a remarkable evolution since its conception over 10 years ago. A number of important observations, including the recent publication of a large randomized clinical trial, have provided further insight into our understanding of intrapartum fetal physiology and intrapartum fetal assessment. The purpose of this paper is to review significant developments in this technology over the past 2 years and to propose paths for future clinical research.
