Abstract
The improvement of heart function are the important consideration for heart failure patient with rotary blood pump (RBP). The capable of function evaluation depend on good monitoring system, which facilitate the physician for diagnosis. In this study, pressure estimation from measured flow rate for the patients with external RBP support is implemented with the non-invasive technique for cardiac function assessment. Measured flow rate from our mock circulation experiment at difference rotational speeds were used to apply with a notable RBP models. Our purpose is to find the optimal parameter values for pressure estimation from our RBP prototype. MUPD-VAD02 that is the external rotary blood pump for pediatric patients was used in this study. The suitable model for our pump prototype is the linear pressure - flow characteristics relationship with speed dependent resistant (Rp), which appeared linear correlations between estimated and measured pressure in a slope of 0.96 (R2 = 0.9603). In conclusion, the parameters and modified RBP model for pressure estimation of MUPD-VAD02 is developed. © 2013 IEEE.
