A Comparison of the Thermodilution and Impedance Cardiography Methods in the Measurement of Cardiac Output

C.S. Pattichis1 and L.E. Baker lThe Cyprus Institute of Neurology and Genetics, P.O. Box 3462, Nicosia, Cyprus 2Department of Biomedical Engineering, University of Texas at Austin, Abstract- A total of 126 cardiac output values were recorded by the thermodilution and impedance cardiography methods in 8 adult mongrel dogs.

The mean cardiac output in Litres/min,

standard deviation and standard error of the mean percent (SEM%) of the thermodilution and impedance methods were 1.75, ± 0.92, 4.7% and 1.5, ± 0.59 and 3.5% respectively. Results show that the mean values of cardiac output measured by thermodilution and the impedance methods are the same (f test, Not significant at p
