...This method uses a cardiovascular catheter equipped with both a cold water injection port and a semiconductor thermistor that measures temperature changes. The most commonly used catheters at present are the Swan-Ganz catheter for measuring cardiac output and the Webster catheter for measuring local venous blood flow. For the former, the injection port is placed in the right atrium, and the catheter is manipulated along the blood flow so that the thermistor is positioned in the pulmonary artery, and 5 to 10 ml of 0°C, 5% glucose solution is rapidly injected once. *Some of the terminology that refers to the Webster catheter is listed below.
