Perfusion Simulation in a Lunch Box

Published on

This simulator was created to provide a way for a perfusionist to
practice without putting patients at risk. Knowing how to react in a dynamic environment is crucial. Perfusionists must know which action to take in an unpredictable scenario. This device offers a simple one-on one approach which allows the teacher to create scenarios and allow the student to react. By changing variables with simple switches, the teacher can present a challenge that the student may then try to solve.

Perfusion Simulation in a Lunch Box

  2. 2. This simulator was created to provide a way for a perfusionist to practice without putting patients at risk. Knowing how to react in a dynamic environment is crucial. Perfusionists must know which action to take in an unpredictable scenario. My device offers a simple one-on- one approach to allow the teacher to create scenarios and allow the student to react. By changing variables with simple switches, the teacher can present a challenge that the student may then try to solve. PDS Perfusion Simulator Prototype
  3. 3. Lights on a display panel will depict the challenge the teacher has set, and the student must correct them using the appropriate methods. While simple situations may prove an easy fix, more complex scenarios can be displayed which offer greater challenge and higher risk. Knowing how to correct these more complex scenarios will offer a student greater ability to deal with the complications that they may face in a real case. The student panel has been designed to provide the most realistic simulation of the heart-lung machines that they operate during real cases. Both dials and switches are used to simulate the correction of deficiencies during open-heart surgery. LED lights on the display panel show current conditions, and reflect the deficiencies set by the teacher or corrections made by the student. Simulator Diagram
  4. 4. Student Response Panel When a perfusionist operates a heart-lung machine, it normal requires at least 16 switches or dials to make adjustments. Over 17 different medications are commonly used during procedures. These all require continuous monitoring. In an ideal bypass operation, the perfusionist must monitor and document events as they occur. For example, Cardioplegia dose, temperature, clamps on or off, pumps on or off, and medications administered are all monitored and documented within the patient record.
  5. 5. The teacher panel controls the errors that are displayed on the display screen. LED lights indicate the problems, which the instructor has created. The student then must react to those situations, toggling switches or dials to correct the problem. If the student reacts correctly, the LED panel lights will switch to green indicating the student has solved the discrepancy. Lights that turn blue indicate the value is too low, and red lights indicate a value is too high. Teacher Control Panel
  6. 6. In summary, the PDS Perfusion Simulator will allow a teacher to simulate real world complications and offer the student the opportunity to learn how to correct these situations prior to facing them during a case. Ideally, the student can use an electronic medical recording program to document the events and learn to use Perfusion Pro on the simulations. By providing real world simulations, the student will be better equipped to face the challenging and dynamic situations they may face during a real case. I have also created an electronic documentation solution that offers complete STS data collection for this very reason. By better understanding the situations that perfusionists Display Panel
