Measuring intracranial and cerebral perfusion pressures following traumatic brain injury

  • A study compared manual and computerized intracranial and cerebral perfusion pressures in individuals admitted to hospital for traumatic brain injury and found significant differences between manual and computerized measurement.
  • The mean difference between manual and computerized pressures were 0.02 mm Hg for intracranial pressure (SD 3.86 mm Hg) and 1.54 mm Hg for cerebral perfusion pressure (SD 8.81 mm Hg).
  • The authors concluded that manual intracranial and cerebral perfusion pressure recordings do not accurately represent true intracranial and cerebral perfusion pressure.
