Claim:
1. A monitor, comprising: a memory device comprising one or more tangible, non-transitory, machine readable media collectively storing one or more sets of instructions; and a processing device configured to execute the one or more sets of instructions to: retrieve a first value representative of a total amount of light emitted by an emitter disposed on a sensor communicatively coupled to the monitor when the sensor is disposed on a tissue of interest; receive a signal generated by a detector disposed on the sensor, wherein the signal is representative of a first amount of light detected by the detector; retrieve a second value from the memory device or the sensor, wherein the second value is a first attenuation coefficient representative of a second amount of light shunting through the sensor; determine a third value based at least in part on the first value, the second value, and the first amount of light, wherein the third value is a second attenuation coefficient representative of the tissue of interest; and determine a physiological parameter based at least in part on the third value.
