Control and manipulated variables differ from device to device as all devices are used for different reasons and are also based on different models. The articles highlights the issue of ventricular assist devices.

The paper reflects on the gap between engineers and clinicians. It shows that engineer can contribute and are highly contributing to the health care industry.
