Abstract
A method and apparatus for ascertaining the cardiac output of a human patient, said method comprising the steps of: measuring the systolic velocity of the blood flowing through the patient's descending aorta; determining the cross-sectional area of the patient's ascending aorta; and calculating the patient's cardiac output from said systolic velocity and said aortic area. The cardiac output can be converted: (1) to cardiac index by dividing it by the patient's body surface area, and (2) to systemic vascular resistance by dividing a value representing the patient's blood pressure by said cardiac output.
