Typical range of wall shear rates and stresses in blood vessels
| Blood vessel . | Shear rate (/s) . | Shear stress (Pa) . |
|---|---|---|
| Large arteries* | 300-800 | 1.4-3.6 |
| Arterioles* | 450-1600 | 2-7.2 |
| Veins* | 15-200 | 0.07-0.9 |
| Stenotic vessels* | 800-10 000 | 3.6-45 |
| Axial flow LVAD† | — | 600 |
| Centrifugal flow LVAD† | — | 150-230 |

Values for different vessels are adapted from Kroll et al74 ; mean wall shear rate/stress values are presented. Peak values could be higher.
Present peak value in typical devices based on experimental measurements and computational fluid dynamics calculations (blood flow rate was 4-7 L/min). These values were summarized from Girdhar et al,75 Selgrade and Truskey,76 and Fraser et al.77
