Problems solved by technology

[0005] Current methods of monitoring fetal health, such as monitoring fetal heart rate, are inefficient at determining levels of fetal distress and sometimes provide false positive results indicating fetal distress, potentially leading to unnecessary cesarean deliveries

Embodiment Construction

[0050] Described herein are systems, devices, and methods for performing transabdominal fetal oximetry, fetal pulse oximetry, and diffuse optical tomography (DOT). The output of fetal oximetry and / or fetal pulse oximetry is the oxygen saturation level of fetal blood (also referred to herein as "fetal hemoglobin oxygen saturation level" and "oxygen saturation level"), which can also be Interpreted as the percentage of hemoglobin in the fetal blood that is bound to oxygen. The output of the DOT is the oxygen saturation level of fetal tissue (eg, brain, skin, muscle, etc.). Oxygen saturation levels in the fetal blood and / or fetal tissue oxygenation levels (e.g., by a trained medical professional) can be used to assess the fetal health and the level of hypoxic stress the fetus may experience during the procedure, For example, during labor and delivery procedures, intrauterine fetal surgery and / or surgery or treatment administered to a pregnant mammal. Oxygen saturation values ​​...

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 afetus 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 by using, forexample, time of flight of photons that correspond to the detected electronic signals. A fetal tissue oxygen saturation level may then be determined by using the isolated portion of the detected electronic signals that correspond to light that was incident upon the fetus.
