摘要： An oximetry device for determining mammalian fetus oxygen levels, the oximetry device constituted of: a sensor module comprising multiple light sources of different wavelengths and at least one optical sensor; a processing unit in communication with the sensor module, the processing unit comprising a processor, and a memory, the processor in communication with an output device, the memory comprising electronically readable instructions to cause the processor to: energize the multiple light sources; determine a time varying amplitude of an output of the at least one optical sensor; asses a quality of a location of the sensor module responsive to the determined time varying amplitude; provide to the output device an indication of the assessment of quality of the location; extract features from the determined time varying amplitude; and output an indication of the mammalian fetus oxygen level responsive to the extracted features from the determined time varying amplitude.
