For … WebHydroxyethyl starch (HES) is a colloid solution that can be used to replace initial blood loss and to treat hypovolemia during surgeries. The local routine at hospitals is to use HES 130/0.42 (molecular weight 130 kD and substitution degree of 0.42) for hemodynamic stabilization and initial blood loss replacement [1, 2].
⇒The importance of viscosity may be shown in the following areas: 1. While pouring oil into your vehicle, you need to take care of its viscosity. Viscosity decides the oil consumption in your vehicle. Moreover, the fluid’s viscosity index is low; then, during summer, it becomes thinner. Thus, you need to use fluid with … See more Every movement is accompanied by friction. When it comes to fluids, one of the most essential terms you’ll come across is viscosity. The … See more The following describes the difference between high and low viscosity: Viscosity is the relative property. If you consider air and water, water has a higher viscosity than air as the air feels less resistance while flowing than … See more ⇒High viscosity means the fluid feels high resistance between the adjacent layers of the fluid during their relative motion. As high viscous fluids have high internal friction between … See more The viscosity of some common fluids is mentioned in the chart below, ranging from low to high. Fluids with extremely high viscosity, such as peanut butter and pitch, act like solids.
