  • Cardiac output and right ventricular ejection fraction system
    Patent number: 5383468
    Abstract: A cardiac output and right ventricular ejection fraction computer comprises a catheter, having an indicator injection port which is located at the right ventricular, inserted into an intravascular of a patient and retained therein; thermal detector device, mounted on a distal portion of the catheter, for detecting the temperature of blood ejected from the right ventricle; signal processor device for calculating the right ventricular ejection fraction from a thermodilution curve obtained by detecting variation of the blood temperature measured by the thermal detector device when a indicator is injected into the right ventricular through the catheter; data input device for inputting data to the signal processor device.
