1. A physiological monitoring system comprising:

  • light drive circuitry configured for generating a light drive signal configured to cause one or more light sources to emit a plurality of light signals, wherein the plurality of light signals corresponds to a plurality of wavelengths of light;

    one or more signal inputs configured for;

    receiving a first plurality of light signals that have been attenuated by a first region of a subject, wherein the first plurality of light signals corresponds to the plurality of wavelengths of light;

    receiving a second plurality of light signals that have been attenuated by a second region of the subject, wherein the second plurality of light signals corresponds to the plurality of wavelengths of light; and

    receiving clinical information associated with the subject undergoing an infusion pump procedure for sodium nitroprusside administration; and

    one or more processors configured for;

    monitoring regional blood oxygen saturation (rSO2) of the subject based on the first received plurality of light signals and the second received plurality of light signals;

    detecting a change in the rSO2 of the subject;

    determining status information for the subject based on the clinical information and the detected change in the rSO2 of the subject; and

    triggering an action based on the status information.
