SYSTEMS, DEVICES, AND METHODS FOR PERFORMING TRANS-ABDOMINAL FETAL OXIMETRY AND/OR TRANS-ABDOMINAL FETAL PULSE OXIMETRY USING INDEPENDENT COMPONENT ANALYSIS

摘要

Independent component analysis may be performed on a plurality of detected electronic signals to separate signals within the detected electronic signals that are contributed by different sources. Each of the plurality of detected electronic signals may be received from a separate detector and may correspond to a detected optical signal emanating from a pregnant mammal's abdomen and a fetus contained therein. The detected optical signals may correspond to light that is projected into the pregnant mammal's abdomen from a light source. The separated signals may be analyzed to determine a separated signal that corresponds to light incident upon the fetus, which may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. An indication of the fetal hemoglobin oxygen saturation level may then be provided to the user.
