ABSTRACT:
An apparatus and method for measuring cardiac output in a patient, The sensed pulsatile component of light at at least two wavelengths transmitted through or reflected from a site on the patient is measured. The measurements are used to calculate the relative concentration of an indicator dye relative to a reference dye, the concentration of the latter being known. Calibrated absolute concentration time curves are then calculated for the indicator dye.
