Continuous fetal cerebral blood flow monitoring during labor: A feasibility study

•A new ultrasound system may enable fetal cerebral blood flow monitoring in labor.•Fetal CBF monitoring can provide an adjunct measure of fetal wellbeing during labor.•Continuous fetal CBF monitoring was feasible in 64 % of the subjects.•Most fetuses (75 %) had stable cerebral blood flow during uterine contractions.•System improvements are needed to secure uninterrupted attachment and Doppler signal.
