Use of a microcomputer in the intensive care unit.

A microcomputer was programmed by ICU personnel to serve as a ready-reference manual data organizer, and source of continuing education. All members of the ICU staff can use the system at any time and no prior training in computer technology is required. Ten programs dealing with common clinical situations are in use, including arterial blood gas analysis, electrolyte analysis, differential diagnosis of shock, adverse drug interactions, inotrope calculations and infusion rates, ventilator management and trouble-shooting, management of intravenous hyperalimentation, derived cardiovascular variables, and coronary risk factor analysis and management. Medication errors have almost been eliminated with use of the computer. Total cost of the system is less than $5000.
