Quantitative Laser Doppler Flowmetry
vii-Abstract Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. The first i...
متن کاملMultiscale entropy of laser Doppler flowmetry signals in healthy human subjects.
PURPOSE The cardiovascular system (CVS) regulation can be studied from a central viewpoint, through heart rate variability (HRV) data, and from a peripheral viewpoint, through laser Doppler flowmetry (LDF) signals. Both the central and peripheral CVSs are regulated by several interacting mechanisms, each having its own temporal scale. The central CVS has been the subject of many multiscale stud...
متن کاملEvaluation of Carpal Tunnel Syndrome by Laser Doppler Flowmetry
Background:Autonomic disturbance can leads to blood flow changes that can be studied by various methods. Objective: To assess the blood flow changes in patients with severe carpal tunnel syndrome by laser Doppler flowmetry Methods:Ten patients with severe unilateral carpal tunnel syndrome confirmed by electrodiagnostic examination enrolled in this study. Patients comprised one man and nine wom...
متن کاملLaser Doppler flowmetry in manual medicine research.
Laser Doppler flowmetry (LDF) is commonly used in combination with reactivity tests to noninvasively evaluate skin sympathetic nerve activity and skin microvascular function. In manual medicine research, LDF has been used as a marker for global peripheral sympathetic nervous system function, but these results should be considered with caution because skin sympathetic nerve activity physiology i...
متن کاملAssessment of retinal and choroidal blood flow changes using laser Doppler flowmetry in rats.
PURPOSE A new noninvasive laser Doppler flowmetry (LDF) probe (one emitting fiber surrounded by a ring of eight collecting fibers, 1-mm interaxis distance) was tested for its sensitivity to assess the retinal/choroidal blood flow variations in response to hypercapnia, hyperoxia, diverse vasoactive agents and following retinal arteries photocoagulation in the rat. MATERIALS AND METHODS After p...
