We have developed a new estimation method that uses neural networks within the remote monitoring system of artificial heart implants, which estimates blood pressure based on artificial heart driving data (motor current and motor rotational angle data). The blood pressure is estimated by separating the mean pressure component from the pulsatile pressure component and by calculating each pressure component with respect to the corresponding neural network. Neural networks learn by means of referring to the actual blood pressure of patients leave the hospital, neural networks estimate blood pressure by using artificial heart driving data that have been transmitted by a PHS (personal handy phone system). Results of in vitro experiments show that blood pressure in mock circulation can be estimated with excellent results in the cases of a change in the pump drive rate, change in arterial resistance, or a malfunction of an artificial heart actuator. These results demonstrate that estimation of the blood pressure using neural networks is effective for a remote monitoring system of patients with artificial heart implants.
