What determines blood rheological properties?

Hemorheological parameters determine blood rheological properties.

What determines blood rheological status?

1. Hematocrit.

2. Blood viscosity.

3. Еrythrocyte agregability.

4. Erythrocyte deformability.

What is the danger of causing rheological disorders?

[su_spoiler title=”Answer”]

Increased erythrocyte aggregation, decreased erythrocyte deformation, changed hematocrit and plasma viscosity leads to a blockage of capillaries, a slowed down blood flow and develops a capillary stasis. The result is a lack of oxygen. During erythrocyte aggregation erythrocytes may get damaged and an erythrocyte coagulation factor may be developed, which could cause a rheological catastrophe.[/su_spoiler]

The aim of our work was a red blood cell deformation (rheological rheological ) at rheological degrees of severity of experimental hemorrhagic shock. The study of erythrocyte deformability violation and a compulsory monitoring of this physical value deserve more attention of fundamental and applied sciences. The modeling of hemorrhagic shock of different stages was performed in the group of anesthetized animals by means of standard blood discharge from the femoral artery (2,5 ml – first stage of shock; 5 ml – second stage of shock; 5ml – third stage of shock, n=12).[/su_animate]
