← Critical-care EEG

Background reactivity

Cerebral response to stimulation: reactive, unreactive, SIRPIDs-only, unclear, or unknown.

Criteria & assessment

  • Qualifying change may be in cerebral voltage or frequency, including attenuation.
  • SIRPIDs-only: sole response is a stimulus-induced rhythmic, periodic, or ictal-appearing discharge.
  • Unclear: inadequate test, excessive artifact, or equivocal cerebral change. Unknown: not tested or maximally alert throughout.

Generation & measurement notes
  • Define stimulation protocol and cerebral-change threshold; S01 does not fully specify them.
