The present investigation was performed to evaluate the use of laser-Doppler flowmetry as a means for measuring the blood flow of the microcirculation of the human tympanic membrane. The blood cell flux in the microvascular bed of the normal tympanic membrane was measured in healthy subjects. The laser-Doppler output signals continuously recorded showed a steady value ranging from 70 to about 120 V, as well as spontaneous oscillations (or rhythmical active vasomotion). Our findings show that the laser-Doppler instrument tested seems to be useful for evaluating blood flow changes in the microcirculation of the human tympanic membrane.
本研究旨在评估激光多普勒血流仪作为测量人鼓膜微循环血流量的一种手段的实用性。在健康受试者中测量了正常鼓膜微血管床中的血细胞通量。连续记录的激光多普勒输出信号显示出稳定值，范围从70到约120 V，以及自发振荡（或节律性主动血管运动）。我们的研究结果表明，所测试的激光多普勒仪器似乎可用于评估人鼓膜微循环中的血流变化。
