Validity of indicator-dilution determinations of cardiac output in patients with mitral regurgitation.
mHE indicator-dilution method has been widely employed for determination of cardiac output since its introduction by Stewart' and Hamilton and associates.2 The effect of unrecognized recirculation of indicator particles upon the primary indicator time-concentration curve has caused concern as to whether this method may be employed in such conditions as mitral regurgitation3' 4and as to whether ...
متن کاملComparison of left ventricular and pulmonary arterial injection sites in determination of cardiac output by indicator dilution technique.
Cardiac outputs calculated from left ventricular indicator dilution curves were compared to outputs calculated from pulmonary arterial curves in 58 patients with a variety of cardiac abnormalities. Cardiac outputs calculated from left ventricular and pulmonary arterial curves differed by only 0.037 ± 0.052 LI mm. Individual measurements of cardiac output using left ventricular curves had an est...
متن کاملDetermination of cardiac output in the mouse.
A technique is described for determination of cardiac output in the mouse. The method is basically a tracer dilution technique using 86-rubidium as soluble indicator, where a microsampler is used for blood collection and in which the gamma function fitting is applied for area determination.
متن کاملCardiac output in normal men during steady-state exercise utilizing dye-dilution technique.
Measurement of cardiac output by various methods in both health and disease has received considerable attention lately. Because of the understandable hesitancy of investigators to subject normal subjects to prolonged, vigorous exercise in the upright position during cardiac catheterization, few observations of man's cardiac output in his normal exercising position have been made (Chapman and Fr...
متن کاملAutomated non-invasive measurement of cardiac output by the carbon dioxide rebreathing method: comparisons with dye dilution and thermodilution.
The accuracy and reproducibility of indirect measurement of cardiac output at rest by the carbon dioxide rebreathing (indirect Fick) method with an automated respiratory analysis system (Gould 9000IV) were compared with simultaneous measurements made in duplicate by dye dilution and thermodilution in 25 patients having cardiac catheterisation studies. Measurements of cardiac output by the carbo...
