Fetal Pulse Oximetry
Fetal Pulse Oximetry using NIRS
During labor, fetal monitoring is typically done by the electronic fetal monitor, which measures the fetal heart rate and maternal contractions. If a non-reassuring fetal heart rate is observed, emergency C-sections are performed to prevent fetal hypoxic injuries. To improve maternal and fetal outcomes and reduce unnecessary C-sections, we propose to use transabdominal fetal pulse oximetry, which uses NIR light to directly measure the fetal arterial oxygen saturation (spo2) non-invasively through the maternal abdomen.
In this project we are developing algorithms for distinguishing maternal and fetal signals, and calculating the fetal spo2. Multi-layer analytical models for NIRS and photon simulations in realistic 3D models were studied for the algorithm development.Recent News
