A microcomputer based simulation of the important processes which occur during cardiopulmonary bypass has been developed for preclinical practice for perfusion technologist trainees. The interface to the computer is through a custom designed electronic console with controls for five pump heads, heat exchanger water temperature, gas flow and content, oxygenator and cardiotomy reservoir heights, clamp detection for flow control and variable venous clamping. A keypad is provided for menu driven entry of patient characteristics, timer control, data requests, drug and fluid administration and perfusion system data.
The system operates in real time with waveform and digital data displays of information typically available to the perfusion technologist clinically. The timing and accuracy of the presented information is controlled by the program and patient responses calculated with randomly selected deviations.
Major components of the simulation have been compared to clinical data. Mean error for oxygen content was 0.67%, for CO2 transfer -0.014ml/l/min and for heat exchanger performance -0.018°C. The simulation has been used for preclinical student training and found to be effective for both practice and student evaluation.
Key words: Computer / simulation / cardiopulmonary / surgery / training
