6/21/2023 0 Comments Blood plasma viscosity![]() The viscosity measured by this algorithm then is compared with the results of a viscometer. Using this velocity, plasma viscosity can be estimated using force balance on red blood cells. Image processing techniques are used to detect red blood cells and their respected velocity. An experimental set-up is designed using transparent polydimethylsiloxane (PDMS) material and video microscopic system. In this method blood viscosity is measured by finding red blood cells terminal velocity in sedimentation. The plasma viscosity cannot diagnose any rheumatoid disease, but when taken in conjunction with a clinical assessment, a result in the range of 1.75-2.00 mPa. Asymptomatic patients with an elevation in the serum viscosity do not require plasma exchange, and the majority will have other indications for therapeutic intervention. In the hypothermic condition plasma showed shear rate. Plasma hyperviscosity is a rare complication of both monoclonal and polyclonal disorders associated with elevation of immunoglobulins. In this paper an innovative method is suggested to measure blood viscosity which does not require separating the red blood cells from plasma and it is done in a very small amount time. at 37C and Newtonianlike behavior was observed at the same temperature. This process is time consuming and needs expensive viscometers. From a macro-rheological point of view, it is known that, the viscosity of blood is directly proportional to the hematocrit (concentration of red blood cells) 11, 41, meaning that, an increase or decrease of the RBC concentration affects blood viscosity values, as well as its non-Newtonian behavior, which is lost at low hematocrit 42. The stimulated light emission of the molecular rotors mixed in the plasma. Such risk factors are related to renal function and lipid profiles. Plasma viscosity was 1.6 mPa s, and the mixtures ranged up to 4.5 mPa s (21C). Usually to measure the plasma viscosity, red blood cells should be separated from a whole blood. Blood viscosity is a physiological variable associated with a number of cardiovascular risk factors in hypertensive patients. This parameter is linked to several diseases in human. Blood viscosity, a measure of the resistance of blood flow, related to its thickness and stickiness, is one of the main biophysical properties of blood. Abstract-Plasma viscosity is an important parameter in biology and fluid mechanic. ![]()
