血流速度是微循环血液动力学的主要指标。由于微循环成份的维度小,信号弱,测量大血管中血流速度的方法是不适用的。多年来,人们只靠目视估量或掐表的方法[1],它对快速多变的微循环血流速的测量常不能准确。Branemark等[2]提出用“飞点”方法测量动物透明组织中微循环的血流速度。参考此原 Blood flow velocity is a major indicator of microcirculation hemodynamics. Due to the small size of the microcirculation component and the weak signal, the method of measuring the blood flow velocity in a large vessel is not suitable. Over the years, people rely on visual assessment or pinch table method [1], its rapidly changing microcirculation blood flow measurement often can not be accurate. Branemark et al [2] proposed using the “flying spot” method to measure the microcirculation blood flow velocity in the transparent tissues of animals. Reference this original
