   Abstract:
   Pulse oximetry (oxygen saturation monitoring) has markedly improved medical care in many fields, including anesthesiology, intensive care, and newborn intensive care. In obstetrics, fetal heart rate monitoring remains the standard for intrapartum assessment of fetal well being. Fetal oxygen saturation monitoring is a new technique currently under development. It is potentially superior to electronic fetal heart rate monitoring (cardiotocography) because it allows direct assessment of both fetal oxygen status and fetal tissue perfusion. Here, we present feasibility studies for trans-abdominal fetal cerebral pulse oximetry. Our experiments on more than 20 patients indicate feasibility. We will present the methodology for obtaining these data, as well as a summary of our pilot clinical study.
