Physiological variables associated with cerebral ischaemia (brain tissue oxygen pressure <15 mm Hg)

Adjusted ORCIp Value
Cerebral perfusion pressure0.980.97 to 0.990.004
End tidal CO20.940.90 to 0.97<0.001
  • A longitudinal multivariable logistic regression model was used that accounted for within-subject and between-subject variations over time (generalised estimated equation analysis) and after adjusting for intracranial pressure, core temperature and Glasgow Coma Scale.
