MECHANICAL MODEL OF THE CARDIOVASCULAR SYSTEM: DETERMINATION OF CARDIAC OUTPUT BY DYE DILUTION


This paper deals with the experimental implementation of one of the methods for the determination of cardiac output – the dye dilution. Measurement is performed on a mechanical model of the cardiovascular system. It is a specific and experimental measurement intended mainly for educational purposes. It was created a real model of bloodstream at author’s workplace. The model enables to set a pulsatile flow of the fluid with defined pressure and flow rate. This experiment is to demonstrate the principle of determination of cardiac output using the dilution methods. This paper is focused only on measuring by dye dilution method. The measurement results are verified by using a Doppler sonography and volumetric containers.

Keywords:
cardiovascular system, cardiac output, dye dilution
