METHOD AND APPARATUS FOR DETERMINING TISSUE HYDRATION
First Claim
1. A system for the measurement of a tissue hydration value in a subject, comprising:
- a microprocessor;
a sensor system comprising a light source and a light detector;
wherein the microprocessor is operatively connected to the light source and light detector; and
the microprocessor can control the light and is programmed with a tissue hydration model that utilizes a measurement of light intensity received by the light detector from light projected from the light source after the light passes through or is reflected by a tissue of the subject to determine the tissue hydration value for the subject.

Abstract
The present invention provides a system for the measurement of a tissue hydration value in a subject comprising a microprocessor and a sensor system having a light source and a light detector. Light is projected from the light source towards the tissue of a subject. The light projected either passes through or off of the tissues of the subject and is then received by the light detector. The light detector transmits a measurement of light intensity received by the detector to the microprocessor. The microprocessor is programmed with a tissue hydration model that utilizes the measurement of light intensity to determine the tissue hydration value for the subject.
