1. A method of measuring at least one parameter of the cardiovascular system of a subject comprising:

  • a. administering to the circulatory system of a subject a detectable amount of at least one indicator;

    b. applying a first wavelength of light for exciting the indicator within the cardiovascular system and causing the indicator to emit a second wavelength of light, c. detecting the magnitude of intensity of the second wavelength of light emitted from the indicator in the circulatory system using at least one photodetector proximately located to a detection area of the subject;

    d. analyzing mathematically the detected magnitude of intensity of the second wavelength of light to compute at least one parameter of the cardiovascular system of the subject.
