For the purpose of this article, normal adult ICP is defined as 5 to 15 mm Hg (7.5–20 cm H2O). ICP values of 20 to 30 mm Hg represent mild intracranial hypertension; however, when a temporal mass lesion is present, herniation can occur with ICP values less than 20 mm Hg [5].
One may also ask, how do you assess ICP in children?
Various methods of ICP monitoring are detailed: non-invasive, indirect (lumbar puncture, visual-evoked potentials, fontanelle compression, and optic nerve sheath), and direct assessment (ventricular cannulation, and epidural, subdural, and intraparenchymal devices).
Simply so, what is considered high CSF pressure?
The diagnosis is also confirmed by detecting a high spinal CSF pressure reading, usually greater than 250 mmH2O or 25 cmH2O (200-250 mmH2O or 20-25 cmH2O is considered borderline high) and normal laboratory and imaging studies including CT scans and MRIs.
