Abstract
A system and method for determining physiological parameters of a patient based on light transmitted through the patient. The light may be transmitted via a broadband light source and received by a detector. The light may be selectively detected at a detector. Based on material characteristic of the detector, specific wavelengths of light are detected by the detector for use in monitoring the physiological parameters of the patient.
