| 摘 要： | 通常在判断血压状态时,先划一个界限,然后将实际血压与这个界限作比较,以此来判断血压状态。这样的判断强调了血压的现值,而没有将血压变化率的信息展现出来。提出血压状态分析法,包括血压状态图和血压稳定性。以家兔为对象、去甲肾上腺素为扰动剂,采集动物在给药前血压平稳期、药物起效期、快速上升期、剧烈振荡期、血压恢复期和给药后血压平稳期的血压数据,建立血压反馈控制系统数学模型结构和血压状态图。根据采集的血压数据,分析血压状态图中血压的稳定态和稳定域、血压变化率的稳定域。通过动物实验,对这种血压状态分析法进行检验,为进一步研究血压控制技术提供新理论和新方法。

| Abstract: | The state of blood pressure(BP) is usually judged by comparing a measured BP value with a preset standard,which emphasizes existing BP value without exhibiting information of the variation rate of BP.We proposed a BP state analysis method,including a state-chart and an analysis of stability for BP.The data of BP from rabbits were collected by a physiological recorder during BP calm period before noradrenaline delivery,onset effect,speediness raise,violently flapping,BP recover and BP calm period after the d... |
