Algorithm Steps

  1. Start

    Suspected Elevated ICP

    Clinical signs or radiographic evidence

    1. Action

      Recognize ICP Signs

      Clinical indicators

      • Headache, vomiting, papilledema (chronic)
      • Altered consciousness (acute)
      • Cushing triad: HTN, bradycardia, irregular respirations
      • Pupil changes (unilateral dilation)
      • Posturing (decorticate/decerebrate)
      1. Action

        Immediate Measures (Tier 0)

        Basic interventions

        • Head of bed 30°, head midline
        • Avoid jugular compression
        • Treat fever aggressively (goal <38°C)
        • Treat pain and agitation
        • Ensure adequate sedation if intubated
        1. Decision

          Impending Herniation?

          Immediate life threat

          • Fixed dilated pupil(s)
          • Rapid neuro deterioration

                    If not already surgical candidate

                    • EVD preferred (allows CSF drainage)
                    • Parenchymal monitor alternative
                    • Target ICP <22 mmHg (BTF)
                    • Target CPP 60-70 mmHg
                    1. Action

                      Tier 1 ICP Management

                      First-line medical therapies

                      • CSF drainage via EVD (10-20 mL prn)
