1. A non-invasive, continuous, real-time detection system for determining an amount of tissue hypoperfusion in a patient, comprising:

  • an illumination system adapted to illuminate a section of tissue of a patient with light comprising at least five wavelength components;

    a detection system arranged to detect light from said illumination system after said light has passed through said section of tissue; and

    a signal processing system adapted to communicate with said detection system,wherein said signal processing system is configured to calculate a relative amount of each of five forms of hemoglobin compared to substantially total hemoglobin, said five forms of hemoglobin being oxy-hemoglobin, deoxy-hemoglobin, met-hemoglobin, carboxy-hemoglobin, and sulf-hemoglobin,wherein said signal processing system outputs information concerning detected sulf-hemoglobin for determining said amount of tissue hypoperfusion, andwherein said illumination system and said detection system are adapted to be at least one of stuck on, clamped on, or attached to an external region of said patient'"'"'s body.
