Figure 1.

a - c: Course of mean arterial blood pressure (MABP), intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in the control group (group 1) and the SAH-groups (groups 2 – 6). ICP steeply increased rose after SAH in all groups and declined to only moderately elevated values within 30 minutes. MABP only moderately increased after SAH. Accordingly, CPP declined immediately after SAH, reached a peak after a few minutes but recovered until the end of the monitoring time. Results are presented as mean ± SEM (* p < 0.05 compared to the control group, one-way ANOVA).
