A new method of measuring cardiac output in man using lithium dilution.
We describe a new indicator dilution method of measuring cardiac output in man. A bolus injection of lithium chloride 0.6 mmol was given via a central venous catheter and arterial plasma [Li+] recorded using a specially developed sensor incorporating an Li(+)-selective electrode. Cardiac output was derived from the lithium dilution curve, with a correction for packed cell volume. Lithium diluti...
متن کاملLithium dilution cardiac output measurement in oleic acid-induced pulmonary edema.
OBJECTIVE To determine whether lung injury influences the accuracy of lithium dilution cardiac output (CO) measurement. DESIGN Animal experimental study. SETTING Animal experimental laboratory. PARTICIPANTS Swine (n = 23) weighing 26.4 +/- 2.47 kg (mean +/- SD). INTERVENTIONS The animals were anesthetized and tracheotomized, then a pulmonary artery catheter was inserted into the right j...
متن کاملComparison of the accuracy of the lithium dilution technique with the thermodilution technique for measurement of cardiac output.
A new indicator dilution technique for measurement of cardiac output is described. Lithium chloride is injected via a central venous catheter and its dilution curve measured in arterial blood using a lithium-selective electrode. We assessed the lithium dilution cardiac output measurement (LiDCO) and a conventional thermodilution cardiac output measurement (ThDCO) by comparing the results of bot...
متن کاملContinuous cardiac output monitoring with pulse contour analysis: a comparison with lithium indicator dilution cardiac output measurement.
OBJECTIVE Pulse contour analysis can be used to provide beat-to-beat cardiac output (CO) measurement. The current study sought to evaluate this technique by comparing its results with lithium dilution CO (LiCO) measurements. DESIGN Prospective, observational study. SETTING Surgical intensive care unit. PATIENTS Twenty-two patients after cardiac or major noncardiac surgery. MEASUREMENTS ...
متن کاملEvaluation of hemodynamic measurements, including lithium dilution cardiac output, in anesthetized dogs undergoing ovariohysterectomy.
OBJECTIVE To measure cardiac output in healthy female anesthetized dogs by use of lithium dilution cardiac output and determine whether changes in mean arterial pressure were caused by changes in cardiac output or systemic vascular resistance. DESIGN Prospective clinical study. ANIMALS 20 healthy female dogs. PROCEDURE Dogs were anesthetized for ovariohysterectomy. Ten dogs breathed spont...
