1. A method comprising:
determining information regarding a blood oxygen value of a fetus, the determining comprising:
obtaining at least one signal indicating light detected from a pregnant mammal's abdomen and/or a fetus disposed in the pregnant mammal's abdomen following application of light to the pregnant mammal's abdomen; and
analyzing the at least one signal using at least one trained model trained, using both results of simulations of light applications to pregnant mammal abdomens and results of light applications to pregnant mammal abdomens, to determine blood oxygen information used to determine the information regarding the blood oxygen value of the fetus.
