First Claim
1. A system comprising:
- a housing configured to house a first light source, a second light source, a detector, a transceiver, and a power source;
the first light source adapted to project light of a first wavelength into the abdomen of a pregnant mammal toward a fetus contained therein;
the second light source adapted to project light of a second wavelength into the abdomen of the pregnant mammal toward the fetus;
the detector, the detector being adapted to detect light reflected from the pregnant mammal'"'"'s abdomen and the fetus and convert the detected light into an electronic reflected signal and communicate the electronic reflected signal to the transceiver;
the transceiver, the transceiver being adapted to receive the electronic reflected signal from the detector and communicate the received electronic reflected signal to a processor;
the power source electrically coupled to the first light source, the second light source, and the detector, the power source being adapted to provide electrical power to first light source, the second light source, the detector, and the transceiver; and
the processor configured to receive the electronic reflected signal from the detector and isolate a portion of the reflected electronic signal that is reflected from the fetus, analyze the isolated portion of the reflected electronic signal to determine a fetal hemoglobin oxygen saturation level of the fetus, and provide an indication of the oxygen level of fetal blood to a display device.

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.
