US 2026/0123879 A1 · SYSTEMS, DEVICES, AND METHODS FOR DETEREMINING A FETAL OXIMETRY VALUE USING AN IN VIVO FETAL OXIMETRY MODEL AND/OR AN AUGMENTED IN VIVO FETAL OXIMETRY MODEL

Abstract

A physiological indicator for a pregnant mammal and/or her fetus may be used to augment and/or personalize a fetal oximetry model to the pregnant mammal, the fetus, and/or the pregnant mammal/fetus pair. Light transmission data that corresponds to and/or represents a composite of light that passes through the pregnant mammal's abdomen and the fetus may be received and input into the augmented fetal in vivo fetal oximetry model. An output from the augmented fetal in vivo fetal oximetry model that includes an indication of an oximetry value and/or wellness for the fetus may be generated and/or received.

Dependent claims

A method comprising:

receiving, by a processor, a physiological indicator for a pregnant mammal or the pregnant mammal's fetus;
receiving, by the processor, light transmission data, the light transmission data corresponding to an optical signal that is detected by a photodetector and converted into the light transmission data, the optical signal being a composite of light that passes through the pregnant mammal's abdomen and a fetus disposed within the pregnant mammal's abdomen;
inputting, by the processor, the light transmission data into an augmented fetal in vivo fetal oximetry model, the augmented fetal in vivo fetal oximetry model incorporating the physiological indicator;
and
receiving, by the processor, an output from the augmented fetal in vivo fetal oximetry model, the output including an indication of an oximetry value for the fetus.
