本文给出了一种自适应血压控制方察,用这种方案设计的闭环计算机控制回路已在皇家墨尔本医院使用。该控制方案的基本设计思想是:基于临床经验和泵最小能运行的阶跃变化值,分高、中、低药物敏感性程度,建立误差信号与注射率阶跃关系对照表(look-up table),按模型参考自适应设计方案,对病人药物敏感性变化进行系统参数的自适应调整。该系统运行时,每隔5秒采样一次平均动脉压(MAP),隔2分钟执行一次控制动作,控制量根据最后6次取样的滑动平均值计算。把2分
In this paper, an adaptive blood pressure monitoring system is presented. A closed-loop computerized control circuit designed with this protocol is used at Royal Melbourne Hospital. The basic design idea of this control scheme is to establish a look-up table (step-by-step) of error signal and injection rate based on the clinical experience and the step change value of minimum pump operation, ), According to the model reference adaptive design, the patient’s drug sensitivity changes in the system parameters adaptive adjustment. When the system is running, the average arterial pressure (MAP) is sampled every 5 seconds and the control action is performed every 2 minutes. The control amount is calculated based on the average of the last 6 samples. Take 2 points
