Calculated apparent blood viscosity and tube hematocrit.
(a) Calculated apparent blood viscosity versus diameter of vessel for different values of systemic hematocrit. (b) Tube hematocrit versus systemic hematocrit (dashed line HT = HSYS is shown for comparison).
Table 2.
Dependence of computed model parameters on hematocrit.
Fig 2.
Calculated resistance of the individual vessel (a) and of the whole vascular level (b) for different values of systemic hematocrit.
Fig 3.
Calculated total cerebral resistance (a) and CBF (b) versus gestational age for different values of systemic hematocrit.
The red lines show the values calculated using the constant blood viscosity μ = 0.003 Pa ⋅ s.
Fig 4.
Mean values with standard deviations averaged over gestational age.
(a) Measured systemic hematocrit. (b) CBF calculated for HSYS = 45% (dashed lines) and for HSYS from clinical records (solid lines).
