微循环压力是微循环观测中不可缺少的项目。目前,许多地方测定这个项目都是采用老办法。即先在显微镜下观察循环的血流情况,然后加压阻断血流,再减压逐渐使血流恢复。当第一个血球流过,即血流开始移动,到血流完全恢复至加压前时的状态,这两个时刻所对应的压力计指数即为微循环压力。这种测量方法的缺点是,1.误差大;2.重复性差;3.长时间于镜下观察易使人疲痨;4.需两人操作,比较麻烦。为了克服这些缺点,我
Microcirculation pressure is an indispensable item in microcirculation observation. At present, the determination of this project in many places adopts the old method. The first observation of the blood circulation under the microscope, and then block the flow of blood pressure, and then gradually decompression to restore blood flow. When the first blood flow, that is, blood flow began to move to the state of blood flow completely restored to pre-pressure, the two points corresponding to the pressure gauge index is the microcirculation pressure. The shortcomings of this measurement method is that 1. The error is large; 2. Repeatability; 3. Long time under the microscope easy to make people tired; 4. Need two people to operate, more trouble. In order to overcome these shortcomings, I
