The Milwaukee School of Engineering (MSOE) has developed a perfusion training simulator to help students become familiar with the hemodynamics of cardiopulmonary bypass (CPB). The purpose of this master's essay is to analyze and evaluate the present condition of the perfusion simulator to determine how close the simulations are to real CPB and what direction the project should take. The most important CPB experience was determined to be the initiation/termination of bypass, which was made possible in the original design with the addition of a venous reservoir in the system. The MSOE mock circulatory loop attempts to simulate both the resistive and compliant properties of the vascular system. In realiity, the loop predominantly displays only a resistive element. The compliance remains constant throughout each simulation. The systemic vascular resistance (SVR) of the mock circulatory loop is an independent variable controlled by the software from the SVR of patient data logs. The simulated SVR was found to be greater than the data log SVR which causes the user to pump at low fluid rates. The proper operation of the loop's flow meter and pressure values were verified. Initiation/termination of CPB was found to be possible when a venous reservoir was added to the present MSOE perfusion simulator. The project's next recommended step is to correct the excessive resistance found in the loop.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .T57 1997 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
