Cerebrospinal Fluid Pressure Measurement Guidelines

Clinical Interpretation and Measurement Considerations

• Opening pressure is typically elevated above 20 cmH₂O in bacterial meningitis, according to the Infectious Diseases Society of America 1, 2
• Pressures ≥25 cmH₂O may indicate intracranial hypertension requiring urgent intervention, particularly in the context of infection or trauma, as suggested by the Infectious Diseases Society of America 3
• Elevated CSF pressure (>25 cmH₂O) may suggest conditions such as bacterial meningitis, according to the Infectious Diseases Society of America 1, 2
• Traumatic brain injury with increased intracranial pressure is associated with elevated CSF pressure, as reported by the American Society of Anesthesiologists 4, 5
• CSF opening pressure should always be measured when performing a lumbar puncture, except when done in sitting position, as recommended by the Infectious Diseases Society of America 1, 2
