9. Hemodynamic Simulator II
Technical Risk Assessment
Pump Design
Actuator not function at its optimal level
Excessive compliance in the circulatory loop
Fluid inertia may cause delay from input to output
Control System
LabVIEW: no previous experience

10. Hemodynamic Simulator II
Current State of Design
Pump Design
Pump design meets all customer needs.
Initially chosen actuator, not powerful enough.
Maximum HR spec. was lowered from 220 to 120 bpm.
Current actuator package meets all customer specs & design requirements.
Manufacturing parts
All material priced & sourced , will be ordered this week.
Atrial, aortic & compliance chambers to constructed over thanksgiving break.
Control System
Two weeks behind schedule due to system modeling.
Developed a test plan for the control system as well as the overall system.
Plans to start building and testing over break
