Bioelectric Impedance

Abstract
The various applications of bioelectric impedance to clinical medicine are illustrated by its use in seven patients. Detection of fluid collections in the pleura, mediastinum, and lung parenchyma; changes in cardiac output; pulsatile flow in an ischemic limb; and lower extremity venous obstruction have all been possible. Bioelectric impedance appears to have promise as a noninvasive, simple, and accurate means of monitoring vital functions.
