1. A method for near-infrared (NIR) cerebral oxygenation level monitoring, comprising:

  • causing an NIR optical source to introduce NIR optical radiation into the cerebral tissue of a patient for migration toward an NIR optical detector;

    receiving a first signal representative of the NIR optical radiation detected by the NIR optical detector;

    processing the first signal to produce a cerebral oxygenation level metric and outputting the cerebral oxygenation level metric on a user display;

    processing the first signal to generate a second signal therefrom known to exhibit measurably significant timewise fluctuations corresponding to at least one intrinsic physiological oscillation in the patient when said NIR optical source and said NIR optical detector are in proper optical coupling with said cerebral tissue;

    detecting whether said measurably significant timewise fluctuations are present in said second signal; and

    outputting an indication of an error condition noticeable to a viewer of the user display if said measurably significant timewise fluctuations are not present in said second signal.
