Mean intracranial pressure (ICP), cerebral perfusion pressure (CPP), and brain tissue oxygen tension (PbtO2
) of 26 aneurysmal subarachnoid hemorrhage patients at given time points after neuromonitoring was started. (A) Mean (standard error of the mean) ICP over the first 144 hours of neuromonitoring. Significant increase of CPP (B) and PbtO2
(C) over time. ***P <0.001. Dashed lines indicate commonly used cutoffs (CPP at 70 mm Hg and PbtO2 at 20 mm Hg). Values are presented as mean ± standard error of the mean.
