Comparison of cardiac output by Fick formula vs. thermodilution, following vasodilator challenge in pulmonary hypertension
Introduction: Cardiac output and index, measured during right heart catheterization are used to define vasoreactivity and predict mortality. The Fick and thermodilution methods are routinely used, but have not been compared following vasoreactivity. Methods: We retrospectively reviewed the RHC data of 50 patients; that met inclusion criteria, of a right heart catheterization with inhaled nitric...
متن کاملContinuous cardiac output measurement: pulse contour analysis vs thermodilution technique in cardiac surgical patients.
We have analysed the clinical agreement between two methods of continuous cardiac output measurement pulse contour analysis (PCCO) and a continuous thermodilution technique (CCO), were both compared with the intermittent bolus thermodilution technique (BCO). Measurements were performed in 26 cardiac surgical patients (groups 1 and 2, 13 patients each, with an ejection fraction > 45% and < 45%, ...
متن کاملComparison of bedside measurement of cardiac output with the thermodilution method and the Fick method in mechanically ventilated patients
INTRODUCTION Bedside cardiac output determination is a common preoccupation in the critically ill. All available methods have drawbacks. We wished to re-examine the agreement between cardiac output determined using the thermodilution method (QTTHERM) and cardiac output determined using the metabolic (Fick) method (QTFICK) in patients with extremely severe states, all the more so in the context ...
متن کاملComparison of cardiac output determined by bioimpedance, thermodilution, and the Fick method.
BACKGROUND Cardiac output can be determined by using a variety of methods. OBJECTIVES To determine the precision and bias between 3 methods for determining cardiac output: bioimpedance, thermodilution, and the Fick method. METHODS Cardiac output was determined by using bioimpedance via neck and thorax patches and thermodilution via pulmonary artery catheter in 46 patients in the intensive c...
متن کاملMeasuring cardiac output: intermittent bolus thermodilution method.
cialist in the cardiac care unit and cardiac observation unit at UCLA Medical Center and is an assistant professor of nursing at the UCLA School of Nursing, Los Angeles, Calif. by a computer and converted into a measurement of cardiac output. Cardiac output is inversely proportional to the area under the curve. The normal cardiac output curve has a rapid smooth upstroke and a gradual downstroke...
