Noninvasive fetal blood oxygen monitoring system and associated method

摘要

A method for non-invasively measuring the oxygen saturation of an in utero fetus's blood using near-infrared spectroscopy. Exemplary methods include placement of a sensor on the outside of the uterus approximate the placenta. Other exemplary methods include inserting a probe into the uterus. Sensors may be positioned approximate a particular portion of the fetus, such as the brain or kidney, to measure the oxygen saturation within the particular portion of the fetus.
