微血管压力情况对机体的微循环状态有着重要作用,直接影响体循环循功能。故对冠心病人进行微血管压力测定有着十分重要的意义。指动脉压,毛细血管压基本上反映了微血管压力。直接法测量精度高,但需要专门设备,操作复杂,不适于临床。本文采用间接法测量指动脉压、毛细血管压,并同步测量血压、正中静脉压对 Microvascular pressure on the body’s microcirculation status has an important role, a direct impact on systemic circulation function. Therefore, coronary heart disease patients with microvascular pressure measurement has a very important significance. Refers to arterial pressure, capillary pressure basically reflects the microvascular pressure. Direct measurement of high precision, but the need for specialized equipment, complex operation, not suitable for clinical. In this paper, indirect measurement of arterial pressure, capillary pressure, and simultaneous measurement of blood pressure, median venous pressure
