Blood Damage Model

Figure 2: Blood Damage Model

Exposure to mechanical shear stress can lead to blood damage (hemolysis). The level of hemolysis depends on many factors including shear stress, load history, current level of hemolysis, duration of exposure and temperature. This figure shows a comparison of the blood damage model with measurements for the threshold levels of shear stress and time of exposure that cause hemolysis in red blood cells. As the exposure time is increased, the level of stress required to cause hemolysis decreases. The power law blood damage model gives excellent agreement with the data.
