Development of Training Support System for Heart-Lung Machine Operation.

Abstract

In education of cardiopulmonary bypass (CPB) for clinical engineers (CE), its long-term on-the-job training (OJT) is often required, in which the burden comes on CE supervising OJT. Thus, in this study, a training support system for CPB is been developing. This system cannot only monitor and warn of reservoir levels but also instruct on operating procedures. Moreover, the line of sight movement can be reduced by projecting the instruction onto the smart glasses which the user wears.The system was tested with the 10 healthy subjects, divided into 2 groups. The group A tried the system first and the human voice guidance second. The group B tried in reverse order. In the result, the group B was better than the group A on the score of availability in the second try. Therefore, this system can be available for use in self-training, after OJT or the learning with human voice guidance.
