AUTOMATED AND COMPUTERIZED MONITORING SYSTEM FOR CARDIOPULMONARY BYPASS WITH A “MAIN FRAME” COMPUTER

Abstract

A new automated and computerized monitoring system for cardiopulmonary bypass (CPB) is developed. The system consists of intelligent terminal units in each operating room and a versatile host computer. The host computer is also connected to the main computer system of the hospital and the subcomputer system of central laboratory to access various information of the patients. During CPB, nineteen biological and CPB information such as blood pressure, temperature, perfusion index and myocardial temperature are accumulated every 30 seconds from the monitoring devices and the CPB machine, displayed on the color monitor in a trend format and stored in the host computer. All the works related to CPB can be also performed easily with this system. The main purpose of the system is to monitor and record various biological information during CPB automatically so as to improve the recordkeeping and to allow perfusionist more time for importantt observations and urgent maneuvers. Furthermore it is expected that these stored data might clarify the pathophysiology of CPB.
