ABSTRACT:
This invention relates to a process of determining continuously and non-invasively (without the withdrawal of blood.) the concentrations of hemoglobin. This is done by measurement of the path length and analysis of the pulsatile component of absorbance of multiple wave lengths of light transmitted through a tissue bed. This invention also relates to the process of simultaneous direct or indirect measurement of the pulsatile arterial width or arterial diameter which is equivalent to the pulsatile path length of the light transmitted across the tissue bed. Measurement of this arterial diameter or pulsatile path length is a prerequisite for non invasive determination of the hemoglobin, hematocrit or pigment concentrations in blood.
