Intracranial Pressure

Aka: Intracranial Pressure, CSF Pressure, CSF Opening Pressure
  1. See Also
    1. Cerebrospinal Fluid
    2. Lumbar Puncture
    3. Cerebrospinal Fluid Examination
  2. Background
    1. Not affected by systemic Blood Pressure
    2. Sensitive to blood pCO2
      1. Hyperventilation lowers Intracranial Pressure
  3. Technique
    1. Counsel patient to try to relax
      1. Avoid Hyperventilation (lowers pressure)
      2. Avoid straining (raises pressure)
    2. Patient lies in lateral decubitus position
      1. Legs and neck should be in neutral position
      2. Opening pressure not accurate in sitting position
  4. Interpretation
    1. Normal
      1. Children <8 years: 10 to 100 mm H2O
      2. Children >8 years: 60 to 200 mm H2O
      3. Adults: 60 to 200 mm H2O
      4. Obesity: 60 to 250 mm H2O
      5. Fluctuation
        1. With pulse: 2 to 5 mm H2O
        2. With respirations: 4 to 10 mm H2O
    2. Decreased: Intracranial Hypotension (uncommon)
      1. Trauma with secondary cerebrospinal fluid leak
      2. Recent Lumbar Puncture
    3. Increased: Intracranial Hypertension

Cerebrospinal Fluid Pressure (C0007809)

Definition (CSP) manometric pressure of the cerebrospinal fluid as measured by lumbar, cerebroventricular, or cisternal puncture.
Definition (MSH) Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.
