WebAbstract. The need to quantify blood flow through the heart has led to the development of different techniques for its measurement. The 3 main approaches are the Fick method, dye dilution, and thermodilution techniques. The latter 2 are based on the use of indicators that indirectly quantify blood flow. These have slowly been developed over ... 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. ethan allen antique rocking chair
