Abstract
Of 22 pairs of cardiac output measurements performed with an electromagnetic flow probe applied to the root of aorta in open chest, anesthetized dogs and with peripheral venous injection of indocyanine green dye and an arterial cuvette, the measurements fell within the range of ± 20% on both sides of the line of identity in 19 instances. In studies on 8 human subjects with radiocardiography and ear dye method performed simultaneously with peripheral venous injection of a mixture of R[131I]SA and indocyanine green, cardiac output given by the ear dye method was higher than that given by radiocardiography by an average of 9 ± 11 (SD)%. Agreement and disagreement in cardiac output measurements given by electromagnetic flow probe, dye dilution method with arterial cuvette, dye dilution method with ear piece densitometer and radiocardiography were discussed.
