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.
