摘　　要：本文阐述了麻醉剂(氨氟醚或异氟醚)与二氧化碳浓度监测系统的微机控制与信息处理子系统.该子系统完成传感器输出电信号与气体分压强的转换、误差的自动校正、非正常情况的报警、吸入与呼出麻醉剂分压及二氧化碳呼气末分压的自动搜索、呼吸频率的检测等任务,使整个监测系统的功能扩展,性能明显提高.The subsystem of control and processing for anesthetic agent (Englurane oflsoflurane) and carbon dioxide monitor system based on infrared is described.The sub-system converts the sensor output signals into the gas concentrations (components ofpressure), corrects the system errors automatically, gives the abnormal alarms, search-es the inspiratory and/or expiratory anesthetic agent concentration automatically,searches the expiratory end tidal CO2 concentration, and detects respiratory rate, andetc. The subsystem expands functions of monitor system and improves its performancesgreatly.
