Hct vs viscosity
WebThe VS-HCT4 was a development of the VS-HCT2 with a case designed to aid mechanical mine laying. The mine's plastic case is rectangular with rounded ends. The mine's … Web1. Hct is the main determinant of blood viscosity, which is also affected by plasma proteins, especially fibrinogen. As Hct increases, viscosity increases, elevating vascular resistance and decreasing blood flow at any given perfusion pressure. As Hct rises above 60%, viscosity tends to increase exponentially. The effects of increased Hct on ...
