Abstract: 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.

Abstract: Fetal tissue oxygenation may be performed transabdominally by, for example, receiving a plurality of detected electronic signals that correspond to light emitted from a pregnant mammal's abdomen and a fetus contained therein that has been detected by the detector and converted into the detected electronic signal. An indication of a depth of the fetus within the pregnant mammal's abdomen may be received and a portion of the detected electronic signals that correspond to light that was incident upon the fetus may be isolated responsively to the indication of the depth of the fetus using, for example, time of flight of photons that correspond to the detected electronic signals. A fetal tissue oxygen saturation level may then be determined using the isolated portion of the detected electronic signals that correspond to light that was incident upon the fetus.

Abstract: Light reflected from a pregnant woman's abdomen and fetus contained therein that has been received by a detector and converted into a reflected electronic signal may be received by a processor. A portion of the reflected electronic signal that is reflected from the fetus may be isolated and the isolated portion of the reflected electronic signal may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. The isolation may be achieved by synchronizing the reflected electronic signal with a fetal heartbeat signal and multiplying the synchronized reflected electronic signal by the synchronized fetal heartbeat signal.

Abstract: Light beams emitted from one or more light sources may be directed into an abdomen of a pregnant mammal toward a fetus contained therein. Some of the light may be reflected by the pregnant woman and fetus and received at a detector over a first time. A photo detector into an electronic reflected signal, which may be communicated to a computer, may then convert the received light. The electronic reflected signal may then be processed and/or analyzed to isolate a portion of the electronic reflected signal reflected from the fetus. The isolated portion of the electronic reflected signal reflected from the fetus may then 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 an operator by way of, for example, a computer display.
