(A–B). Relationship between cerebral perfusion pressure (CPP) and middle cerebral artery mean flow velocity (Vmca) in children post-TBI between ages 10–16.9 years. ICP (mmHg) data are presented for the two patients whose Vmca are high for age and gender. (A) N = 20 boys. Normal Vmca (cm/s) 75 ± 16 cm/s (43–107)** for age and gender denoted by shaded area. Mean Vmca (cm/s) 77 ± 22 (32–123). Mean CPP (mm Hg) 66 ± 16 (34–87). Spearman’s ρ = −0.08; p = 0.7. (B) N = 3 girls. Normal Vmca (cm/s) 89 ± 16 (57–121)** for age and gender denoted by shaded area. Mean Vmca (cm/s) 79 ± 37 (52–134). Mean CPP (mm Hg) 59 ± 22 (31–83).
