Question:

The transfer function that relate-s the change in blood pressure y to a change in u the infusion rate of a drug (sodium nitroprusside) is given by1

The two time delays result from the blood recirculation that occurs in the body, and ? is the recirculation coefficient. The following parameter values are available

Use Simulink to construct the block diagram and simulate the blood pressure response to a unit step change (u = 1) in sodium nitroprusside infusion rate.
