"Orpheus" cardiopulmonary bypass simulation system

Area of Science:

• Medical Simulation
• Cardiopulmonary Perfusion Technology

Background:

• Perfusionists require specialized training for complex cardiopulmonary bypass procedures.
• Current training methods may not fully replicate the dynamic and critical nature of intraoperative events.

Purpose of the Study:

• To describe a high-fidelity simulation system for perfusionist training and continuing education.
• To detail the system's components, capabilities, and potential applications in enhancing perfusion practice.

Main Methods:

• Development of a system including a hydraulic simulator, electronic interface, and real-time computer models.
• Integration with institutional operating theatre equipment (heart-lung machine, monitoring systems).
• Incorporation of a sophisticated blood gas model and pharmacokinetic drug models.

Main Results:

• The simulator accurately reproduces normal and abnormal cardiopulmonary bypass events.
• A detailed blood gas model predicts oxygenator behavior, with outputs updated every 500 milliseconds.
• Pharmacokinetic profiles for various drugs (vasoconstrictors, vasodilators, etc.) are modeled.

Conclusions:

• The simulation system offers a realistic environment for perfusionist skill training.
• It supports the development of crisis management protocols and evaluation of new techniques.
• This technology has significant potential for perfusionist certification and accreditation.
