WebJul 18, 2024 · Estimated blood viscosity was associated with increased in-hospital mortality using two different measures. One-centipoise increase in high-shear blood viscosity was associated with a 36.0% relative increase in death (p < 0.001). A similar increase in low-shear blood viscosity was associated with a 7.0% relative increase in death (p < 0.001). WebMay 21, 2024 · In addition to decreasing the propensity for thrombosis, reducing blood viscosity will increase oxygen delivery because perfusion is inversely proportional to blood viscosity.
