SYSTEMS, DEVICES, AND METHODS FOR PERFORMING TRANS-ABDOMINAL FETAL OXIMETRY AND/OR TRANS-ABDOMINAL FETAL PULSE OXIMETRY A USING AN ACOUSTIC AND/OR ACOUSTO-OPTICAL SIGNAL
Photoacoustic and/or acousto-optical techniques may be used to transabdominally perform fetal oximetry and/or trans-abdominal fetal pulse oximetry. In some cases, a composite acoustic signal that has emanated from an abdomen of a pregnant mammal may be received by a processor from, for example, an ultrasonic detector and/or microphone positioned on, or near, a pregnant mammal's abdomen and the composite acoustic signal may result from an optical signal incident on the pregnant mammal's abdomen and a fetus contained therein. A portion of the composite acoustic signal that was incident on the fetus may be isolated from the composite acoustic signal and then analyzed to determine a fetal hemoglobin oxygen saturation level and/or a fetal tissue oxygen saturation level.
