title: Laser Doppler flowmetry--peripheral microcirculation during cessation of cerebral and cardiocirculatory function.
abstract: 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).
