摘要
研究危重病人生命体征信号准确监控问题。病人处在危重阶段,生命体征信号波动较小,很难产生剧烈的变化。信号变化差异在通过无线传感网络进行传播的过程中,容易由于差异过小发生信息的延迟,衰减,造成信号不能及时传递。传统方法是采用生命体征的明显波动进行报警监控的,一旦病人的生命体征信号过于微弱,不能发生较大的阀值报警,会造成误报警和虚报警。为此,提出了一种增强支持向量机算法的危重病人实时监控方法。对生命体征信号进行增强处理,提高生命体征信号的强度,判断危重病人生命体征信号是否出现异常。从而实现危重病人的实时监控。实验结果表明,改进算法能够提高危重病人监控的准确性。
Research critically ill patients vital signs accurate monitoring problem. This paper proposed an enhancement algorithm based on support vector machine (SVM) method for real - time monitoring of the critically ill patients. Signs of life signal were enhanced to improve the strength of the vital signs and judge Whether the unusual vital signs of critically ill patients appear, so as to realize real -time monitoringof the critically ill patients. The experimental results show that this algorithm can improve the accuracy of the critically ill patients monitoring.
