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.

2. The maternal and fetal monitoring system of claim 1, wherein the controller calculates first values of fHR, mHR, and UA from the biopotential physiological data and the controller calculates second values of fHR, mHR, and UA from the ultrasound physiological data, and the first values or the second values are selected as the calculated fHR values, mHR values, and UA values presented on the graphical display.
- Claim:
3. The maternal and fetal monitoring system of claim 2, wherein the controller further calculates a biopotential signal to noise ratio (SNR) from the biopotential physiological data, calculates an ultrasound SNR from the ultrasound physiological data, and selects between the first values of fHR, mHR, and UA and the second values of fHR, mHR, and UA based upon the greater of the biopotential SNR and the ultrasound SNR.
- Claim:
4. The maternal and fetal monitoring system of claim 3, wherein the controller further compares the biopotential fHR value, biopotential mHR value, the ultrasonic fHR value and the ultrasonic mHR value to calculate a heart beat coincidence between the mHR values and at least one fHR value.
- Claim:
5. The maternal and fetal monitoring system of claim 1, wherein the controller calculates the fHR values, the mHR values, and the UA values using a combination of the ultrasound physiological data and the biopotential data.
- Claim:
6. The maternal and fetal monitoring system of claim 4, wherein the controller further calculates a biopotential signal to noise ratio (SNR) from the biopotential physiological data, calculates an ultrasound SNR from the ultrasound physiological data and weights the contribution of the biopotential physiological data and the ultrasound physiological data to the calculation of the fHR values, the mHR values, and the UA values based upon the biopotential SNR and the ultrasound SNR.
- Claim:
7. The maternal and fetal monitoring system of claim 1, further comprising a biocompatible housing, wherein the ultrasound transducer and the plurality of electrodes are secured within the biocompatible housing.
