The Biological Signal Visualization Algorithm for Heart Surgery Simulator

Yong-Jun Noh, Chun-Ho Chang, Jong-Ha Lee


This paper introduces a bio-signal visualization algorithm for developing a cardiovascular medical virtual training simulator. It provides opportunities for practitioners and specialists who have complicated medical practice to perform enough training exercises. To reimplement the current study operation situation as much as possible, we implemented an algorithm that can easily identify each biological signal based on the patient monitoring system by visualized. In the future, combining physical engines with valid verification of whether they are suitable for actual medical staff and building simulations. That is identical to actual surgical conditions will enable more scenarios for patient diagnosis and more training programs in various healthcare fields. It produces talented individuals with specialized skills for medical personnel by training in multiple health care fields and more patients' conditions. In addition, for emergencies and emergencies in a real surgical environment, patterns through pulse rate/blood pressure changes were implemented when certain values were entered. Users could be given various situations through the WebSocket communication method as a shield to provide them with specific situations (sudden blood pressure reduction, pulse rate rise, and breathing anxiety) suitable for each training scenario. Also, our method interacts with the user in real-time, keeps the signal uninterrupted and continuous when it gives signals such as a particular situation.
