Detection of Site-Specific Blood Flow Variation in Humans during Running by a Wearable Laser Doppler Flowmeter
Wearable wireless physiological sensors are helpful for monitoring and maintaining human health. Blood flow contains abundant physiological information but it is hard to measure blood flow during exercise using conventional blood flowmeters because of their size, weight, and use of optic fibers. To resolve these disadvantages, we previously developed a micro integrated laser Doppler blood flowm...
متن کاملTissue blood flow measurement by laser Doppler technique
Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
متن کاملinduction of focal cerebral ischemia by continuous recording of cerebral blood flow using laser doppler flowmeter in rat
background & objectives: ischemic stroke is the third leading cause of death and disability in most of the human societies. there is no effective treatment due to complexity of the pathophysiological mechanisms. today, more researches are designed to introduce involving factors and new treatment strategies in brain ischemia. the objective of this study is to introduce an experimental model of t...
متن کاملEvaluation of a laser Doppler flowmeter to assess blood flow in human primary incisor teeth.
PURPOSE This study determined whether the portable Advance Laser Flowmeter Model 21, a clinical instrument, would indicate significant values when pulpal blood flow was present or absent; whether the analog output of the flowmeter was time-linked to the heart rate; and whether labial and lingual crown surfaces produced different flow values. METHODS Teeth were tested under two conditions: wit...
متن کاملScanning laser Doppler flowmeter study of retinal blood flow in macular area of healthy volunteers.
AIM To compare the interocular and intraocular differences of capillary perfusion, and the intraocular regional differences of retinal blood flow in the macular area of healthy volunteers. METHODS Tissue blood flow in the macula was examined in both eyes of 20 healthy volunteers with the Heidelberg retinal flowmeter. Blood flow measurements were made in a 10 degrees x 2.5 degrees area superio...
