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 کاملComparison of Transpulmonary Thermodilution and Calibrated Pulse Contour Analysis with Pulmonary Artery Thermodilution Cardiac Output Measurements in Anesthetized Dogs
BACKGROUND Transpulmonary thermodilution (TPTDCO ) and calibrated pulse contour analysis (PCACO ) are alternatives to pulmonary artery thermodilution cardiac output (PATDCO ) measurement. HYPOTHESIS Ten mL of ice-cold thermal indicator (TI10 ) would improve the agreement and trending ability between TPTDCO and PATDCO compared to 5 mL of indicator (TI5 ) (Phase-1). The agreement and TA between...
متن کاملCardiac output measurements during off-pump coronary surgery: comparison between partial rebreathing and pulmonary artery thermodilution.
EDITOR: We read the article by Dr Gueret and colleagues comparing two different methods of cardiac output determination in off-pump cardiac surgery with great interest [1]. Off-pump coronary artery bypass surgery (OPCAB) is an increasingly popular method of myocardial revascularization for both routine and high-risk patients. During positioning the heart for grafting, however, there is potentia...
متن کاملAssessment of thermodilution cardiac output in small subjects.
Thermodilution cardiac output determinations were compared with dye-dilution measurements in normovolemic and hypovolemic puppies. Good correlation was achieved with small volumes of cold and warm saline. Injectate volumes and significant caval displacement of the injectate port did not significantly affect thermodilution output measurements. This study demonstrates that thermodilution is a rel...
