Abstract
Systems and methods of maternal and fetal monitoring include acquiring ultrasound physiological data with an ultrasound transducer. A plurality of electrodes acquire biopotential physiological data from the skin of a patient. A controller receives the ultrasound and biopotential physiological data and calculates fetal heart rate (fHR) values, maternal heart rate (mHR) values, and uterine activity (UA) values from the ultrasound and biopotential physiological data.
