A new pulse contour method to determine stroke volume and cardiac output continuously in patients on a beat-to-beat basis from the aortic pressure wave has been implemented in the form of a simple, inexpensive, fully automatic computing module for a commercially available patients monitoring system (Philips Medical Systems). Its reliability has been tested and shown in a computer analog, in experimental studies in 10 dogs (not reported here), in 22 hemodynamic studies on 20 young healthy volunteers and during 41 days in 20 postsurgical patients in the ICU, the most important result being that erros figures (15 and 19% respectively in the two human studies) are of the same order as when two standard methods, Fick and dye dilution are compared. The clinical studies have further indicated the easy applicability of the module 1 degree in the monitoring of critically ill patients in ICU's, 2 degrees as a monitor of the systemic circulation during anesthesia, and 3 degrees as a tool for studying the hemodynamic effects of pharmacological agents. The instrument consitutes no burden to the patients and has, several times during the course of the evaluation, provided an early warning of a deteriorating hemodynamic status of the patient to the physician.
