Abstract
An edema monitor uses patient-specific measurements of tissue conductivity and tissue perfusion and an empirically developed perfusion coefficient of thermal conductivity to obtain tissue intravascular water and tissue extravacular water components of tissue total water. Edema is an excess of tissue extravacular water. A value for edema is obtained by deducting from the obtained value for tissue extravacular water a normal value for tissue extravacular water.
