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.
