Percentages and absolute numbers of observations with normal (> 20 mmHg), moderately hypoxic (15–20 mmHg), or severely hypoxic (< 15 mmHg) brain tissue oxygen tension (PbtO2) as stratified according to the presence or absence of metabolic crisis (a lactate/pyruvate ratio > 40 and glucose < 0.2 mmol/L in cerebral microdialysate) Patients with subarachnoid haemorrhage (SAH) and traumatic brain injury (TBI) are illustrated in green and purple, respectively.
