The contract supported work in computer applications in intensive care. The central biologic provlem was estimation of the adequacy of blood volume replacement after surgery and trauma the central development problem was to provide computer-based services of sufficient utility to justify manual entry of clinical data. Work done in four areas showed Clinically adequate correlation with electromagnetic flow measurement for cardiac output measurement demonstration of measurable, significant changes during infusion of 50 ml volume aliquots over 4 minutes for estimation of circulatory status smoother maintenance of hemodynamic variables was associated with computer controlled transfusion than with variables was associated with computer controlled transfusion than with manually transfused controls comparison of weighed lung water after pulmonary edema induced in dogs showed good correlation r0.99 with measurements of thermal volume made by double indicator dilution using an instream arterial thermistor-conductivity catheter.
