Static state hemodynamic variables estimation model for the moving-actuator type total artificial heart - Part I - Cardiac output estimation

Cardiac output estimation is a very important study for the artificial hear t. In this paper, we developed a cardiac output estimation model for the mo ving-actuator type total artificial heart (MA-TAH) that was developed at Se oul National University Hospital. The proposed model is simple and provides beat-by-beat mean cardiac output estimation. Moreover, it uses non-invasiv ely acquired signals. Model parameters were adjusted with in vitro data by least mean square (LMS) algorithm. Results showed that the proposed scheme gives a mean estimation error of about 0.1 (l/min) for the given data. This ensures the suitability of the proposed model.
