Outline of Final Research Achievements |
In this study, we sought to investigate whether a monitoring method using parameters to be provided from a ventricular assist device (VAD) driver can be used to acquire bypass flow and biological information. As a result, we improved estimate accuracy of bypass flow by using airflow in filling phase for pneumatic VAD. This monitoring system was implemented on compact pneumatic VAD driving under development. In continuous flow system, it was suggested that the parameters of the driver-side (the input current and time constant for rotational speed) was useful to estimate the state on the load-side when the driving condition was changed. The rotational speed control for a monitoring system was compatible with the adaptive VAD control in the situation of pulsatile circulation.
