"WebThe original dye dilution technology requires direct, continuous, and invasive blood sampling through a cuvette for measurement of the injected indicator (e.g., ICG) in arterial blood for the acquisition of a dye dilution curve. Consequently this cannot be regarded as a clinical method of cardiac output estimation, especially in small children. " - Dye dilution method cardiac output
