Relationship between mean cerebral blood flow velocities (Mean CBFV) and blood flow rates during modified ultrafiltration (MUF) in 31 children (○) after cardiopulmonary bypass. Flow velocities in the middle cerebral artery are expressed in percentages (%) relative to the pre-MUF baseline. Higher blood flow rates of ultrafiltration during MUF were associated with a significant reduction in the middle cerebral artery flow velocities (r = − 0.49; p = 0.005). The horizontal dotted line indicates the baseline (100%) for all patients.

3. Fig 2
Relationship between the absolute changes (Δ) in transcranial mixed venous oxygen saturation (rCVOS) and blood flow rates during modified ultrafiltration (MUF) in 31 children (○) after cardiopulmonary bypass. The Δ rCVOS are expressed as the difference between the values of the rCVOS measured before MUF and those recorded at the end of MUF. The use of high blood flow rates during MUF were associated with a significant reduction in the rCVOS as indicated by more negative values on the Δ rCVOS (r = − 0.49; p = 0.005). The horizontal dotted line indicates no absolute change (Δ rCVOS = 0%).
