Summary
A fully automatic pneumatically driven total artificial heart (TAH) system was developed with the following objectives: (a) Analysis of the circulatory mechanism under normal and abnormal conditions; (b) clarification of the required performance of the TAH pump under various conditions such as rest and exercise; (c) establishing the data acquisition of biochemical factors, neurological factors, exercise, and their feedback to the TAH system.
This system consists of three decentralized processing and control units with a multimicroprocessor, pneumatic driving unit, data processing unit, and digital servo unit; it achieves a rapid response (each pulse), broad controllable range, flexibility of control algorithm, and multichannel control input.
Using this system, predictive control during treadmill exercise was examined. Predictive blood flow rate curves for the TAH were established based the hemodynamic response of normal goats during and after exercise. The system was able to track well the predictive blood flow rate curves.
