Flow regulation in multi branched models of blood vessels.
Experimental models are an important instrument for investigations of flow characteristics in blood vessels. For realistic conditions all essential branches of a vessel need to be simulated and controlled. An outflow controlling system was designed for a study on flow conditions in a cerebral aneurysm model with multi outlets. The volumetric flow varied between the outlets. The construction for...
متن کاملcomparing cerebral blood flow auto regulation in
introduction : cerebral autoregulation (ca) and mean cerebral blood flow velocity in males and females are still under controversy. the present study was scheduled to address the effect of sex on these parameters. materials and methods : the present study was interventional and performed on 30 healthy volunteers (15 males aging from 20-30 yrs and mean age of 23.9±3 years old and 15 females agin...
متن کاملCerebral Blood Flow Regulation
Rapid vascular resistance adjustments in the brain and in the circle of Willis have been continuously measured and enhanced by signal averaging methods. Naftidrofuryl, a drug chemically similar to local anesthetics and to beta adrenergic blocking agents, increases local CBF by reducing resistance in brain and in extracerebral supply arteries. It has also been reported to affect brain metabolism...
متن کاملFunctional sympatholysis and sympathetic escape in a theoretical model for blood flow regulation
A mathematical simulation of flow regulation in vascular networks is used to investigate the interaction between arteriolar vasoconstriction due to sympathetic nerve activity (SNA) and vasodilation due to increased oxygen demand. A network with 13 vessel segments in series is used, each segment representing a different size range of arterioles or venules. The network includes five actively regu...
متن کاملCapillary recruitment in a theoretical model for blood flow regulation in heterogeneous microvessel networks
In striated muscle, the number of capillaries containing moving red blood cells increases with increasing metabolic demand. This phenomenon, termed capillary recruitment, has long been recognized but its mechanism has been unclear. Here, a theoretical model for metabolic blood flow regulation in a heterogeneous network is used to test the hypothesis that capillary recruitment occurs as a result...
