This paper discusses concepts of thermodilution and ejection fraction associated with a typical application of the Swan-Ganz catheter, with the presentation of two models: one for the measurement of cardiac output and another for the measurement of ejection fraction. This work was developed to answer if the response to the impulse of the Swan-Ganz catheter depends on the speed of the blood flow in the right ventricle of the heart. The primary objective of this paper is to develop a method for characterizing the response of the temperature sensors in Swan-Ganz catheters so that it is possible to evaluate whether it is feasible to use deconvolution operations in measurements performed with this type of sensor.The determination of cardiac output and heart ejection fraction can help predict cardiovascular disease and more effectively estimate the risk of sudden death (ejection fraction <0.2), which are becoming more common.
