From: Early brain injury after aneurysmal subarachnoid hemorrhage: a multimodal neuromonitoring study
Percentage of 26 aneurysmal subarachnoid hemorrhage patients with at least one episode (mean hourly value) of brain tissue oxygen tension (PbtO2) below 20 mm Hg, cerebral perfusion pressure (CPP) below 70 mm Hg, and lactate-to-pyruvate ratio (LPR) above 40 in time periods up to 144 hours after neuromonitoring start. *P <0.05 indicates the significant decrease compared with baseline (baseline = time period 0 to 6 hours from neuromonitoring start).
