Abstract
A method of sensing the heart rate and blood oxygen saturation of a maternal patient and a fetal patient can include obtaining maternal electrocardiogram (mECG) data and fetal electrocardiogram (fECG) data with a plurality of electrodes. The method can also include obtaining photosignal data with an optical sensor, the photosignal data including a maternal photosignal component and a fetal photosignal component. Additionally, the method can include applying mECG to the photosignal data to calculate maternal photoplesthograph (mPPG) data, applying the mPPG to the photosignal data to remove the maternal photosignal component from the photosignal data, and applying the fECG to remaining photosignal data to calculate fetal photoplesthograph (fPPG) data.
