  • Methods and systems for determining cardiac output based on a valve cross sectional area estimate
    Patent number: 7789835
    Abstract: Described herein are systems and methods for determining the cardiac output of a patient. One such method includes measuring the patient's height and the velocity time integral or stroke distance of blood flowing from the heart of the patient, and subsequently utilising these measurements to determine the cardiac output of the patient based on a valve cross sectional area estimate.
