![]() ![]() Due to Low flow rate of blood interactions between red blood cells, the plasma protein increases. Since viscosity of blood increases at low flow velocities (e.g., during circulatory shock), blood does not obey Newton’s law, or we can say blood is a non-Newtonian fluid. On the other hand, viscosity of blood is very high in comparison to water, and hence flow-pressure relationship slope will be less in comparison to slope of flow-pressure relationship of water. Hyperviscosity is attributed to abnormally high. It is clear from the graph of flow-pressure relationship of water, that the flow rate of water and viscosity are inversely proportional to each other therefore, when the viscosity is small, then slope of the flow-pressure relationship will have large value, it means, at a particular pressure, flow of water will increase at lower viscosity. Hyperviscosity syndrome is a combination of related symptoms activated by increased blood viscosity (thickness). The viscosity of a fluid is defined as the ratio of. Anyone who takes blood-viscosity reducing drugs should let the physician know all other prescription or nonprescription (over-the-counter) medicines he or she is taking. increased blood viscosity is an independent risk factor for atherosclerotic heart disease and its. This is shown in the figure as a linear dashed line for the flow-pressure relationship of water. Blood-viscosity reducing drugs may interact with a other medicines, changing the effects of one or both of the drugs or increasing the risk of side effects. ![]() For instance, homogeneous fluid like water, obeys Newton’s law hence, viscosity of water does not depend on the velocity of flow of fluid. ![]() Resistance between two adjacent layers of a liquid or fluid depends on the nature of fluid, which means, for homogeneous and heterogeneous composition there will be different resistances between layers of fluid. Viscosity of blood can be explained by Poiseuille's equation. ![]()
