CSF pressure, as measured by lumbar puncture, is 10–18 cmH2O (8–15 mmHg or 1.1–2 kPa) with the patient lying on the side and 20–30 cmH2O (16–24 mmHg or 2.1–3.2 kPa) with the patient sitting up. In newborns, CSF pressure ranges from 8 to 10 cmH2O (4.4–7.3 mmHg or 0.78–0.98 kPa). Most variations are due to coughing or internal compression of jugular veins in the neck. When lying down, the CSF pressure as estimated by lumbar puncture is similar to the intracranial pressure.
