Measuring 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...
متن کاملComparison of uncalibrated arterial waveform analysis in cardiac surgery patients with thermodilution cardiac output measurements
INTRODUCTION Cardiac output (CO) monitoring is indicated only in selected patients. In cardiac surgical patients, perioperative haemodynamic management is often guided by CO measurement by pulmonary artery catheterisation (COPAC). Alternative strategies of CO determination have become increasingly accepted in clinical practice because the benefit of guiding therapy by data derived from the PAC ...
متن کاملPerformance of noninvasive partial CO2 rebreathing cardiac output and continuous thermodilution cardiac output in patients undergoing aortic reconstruction surgery.
BACKGROUND In the partial CO(2) rebreathing method, monitored changes in CO(2) elimination and end-tidal CO(2) in response to a brief rebreathing period are used to estimate cardiac output. However, dynamic changes in CO(2) production during ischemia and reperfusion may affect the accuracy of these estimates. This study was designed to compare measurements of cardiac output as produced by the p...
متن کاملCardiac output monitoring: aortic transpulmonary thermodilution and pulse contour analysis agree with standard thermodilution methods in patients undergoing lung transplantation.
PURPOSE The PiCCO System is a relatively new device allowing intermittent cardiac output monitoring by aortic transpulmonary thermodilution technique (Aorta intermittent) and continuous cardiac output monitoring by pulse contour analysis (Aorta continuous). The objective of this study was to assess the level of agreement of Aorta intermittent and Aorta continuous with intermittent (PA intermitt...
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%, ...
