1. A method comprising:
receiving, by a processor, a plurality of detected electronic signals at least some of the plurality of detected electronic signals being contributed by different sources;
performing, by the processor, independent component analysis on the plurality of detected electronic signals to separate signals within the plurality of detected electronic signals into a plurality of separated signals, each of the separated signals included in the plurality of separated signals corresponding to a different source;
determining, by the processor, a separated signal that corresponds to light incident upon a fetus contained within an abdomen of a pregnant mammal;
analyzing, by the processor, the separated signal that corresponds to light incident upon the fetus to determine a fetal hemoglobin oxygen saturation level of the fetus; and
facilitating, by the processor, provision of an indication of the fetal hemoglobin oxygen saturation level to a user.
