Patent attributes
A system (100) includes a sensor (12A/B/C), a processor (32), and an output module (38). The sensor can have at least one light emitter (16A) and at least one light detector (18A/B). The processor can be coupled to the sensor and have instructions configured to determine a calibration value using light attenuation corresponding to a light path through a tissue associated with a light emitter and a light detector of the sensor. The processor can be configured to calculate oxygen saturation in the tissue using a signal provided by the sensor. The output module can be coupled to the processor and configured to render a compensated oxygen saturation. The compensated oxygen saturation can be determined using the calibration value and the calculated oxygen saturation.
