Photon density wave based determination of physiological blood parameters
A system for measuring a physiological parameter of blood in a patient is presented. The system includes a transmission module configured to emit a plurality of photon density waves into tissue of the patient from a plurality of modulated light sources. The system also includes a receiver module configured to detect characteristics of the plurality of photon density waves. The system also includes a processing module configured to identify characteristics of a pulsatile perturbation of the tissue based on the characteristics of the plurality of photon density waves, and identify a value of the physiological parameter based on at least the characteristics of the pulsatile perturbation of the tissue and the characteristics of the plurality of photon density waves.
