摘　　要：提出了一个针对麻醉术中血容量不足的实时智能监测告警算法:统计告警算法.该算法综合了血压、心率、脉量和呼气末二氧化碳浓度等指标,能够提供足够的诊断支持信息,并可随时调节告警灵敏度,通过Kappa分析,在线状态下新算法与麻醉师的诊断结果一致性为76%;并基于LabVIEW平台设计了算法的系统框图和各功能模块.A real-time intelligent monitoring alarm algorithm called Probabilistic Alarm Algorithm （PA） is pres- ented in this paper. The algorithm integrates four physical indices： blood pressure, heart rate, pulse volume, and the concentration of carbon dioxide at the end of expiratory. It can provide adequate decision support infor- mation and can easily adjust the alarm sensitivity. Experimental results through Kappa eLnalysis show a satisfacto- ry level of agreement （ up to 76% ） between the algorithm and the anesthetist. The system flow chart and each module are designed with LabVIEW.
