Laser Doppler flowmetry (LDF) is a noninvasive method to study the microcirculation. We studied the feasibility of the clinical use of LDF in the intensive care unit by continuously recording different LDF parameters during the cessation of cerebral and cardiocirculatory function. The LDF-Conc (concentration of red blood cells) reflected biological phenomena correlated with the heart rate and microvibration that could not be detected with conventional means (systemic blood pressure, peripheral oxygen saturation).
激光多普勒血流仪（LDF）是一种用于研究微循环的非侵入性方法。我们通过在脑循环和心脏循环功能停止期间连续记录不同的LDF参数，研究了LDF在重症监护病房临床应用的可行性。LDF-Conc（红细胞浓度）反映了与心率和微振动相关的生物学现象，而这些现象是用传统方法（全身血压、外周血氧饱和度）无法检测到的。
