Abstract

Although previous retrospective assessments have demonstrated good agreement between the results of the Fick method and those of indocyanine green dye and thermodilution in the measurement of cardiac output (CO),1-3 they have suggested that the discrepancy between Fick and dye is exaggerated in patients with a low CO and in those with aortic or mitral regurgitation, whereas the Fick-thermodilution difference is not increased in these patients. As a result, thermodilution may be preferable to dye in those with a low CO or left-sided regurgitation. However, no previously published study has measured CO by all 3 techniques in a large number of patients, thereby allowing a direct comparison of dye and thermodilution. The present study was performed for this purpose.
