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 Indicator Dilution Technique is a Useful Method for Measuring Cardiac Output. The indicator dilution technique for measuring cardiac output is also based on the law of conservation of mass and is illustrated by the model in Figure 4-20.
