Intracranial Hypertension (IH)

Intracranial Hypertension is the elevation of pressure in the cranium, often due to head injury. Also called increased ICP (IICP).

ICP of 15-20 mmHg is tolerable for a short time, but ICP above 20 mmHg sustained for more than 2 minutes can be damaging to cells.

Malignant intracranial hypertension is defined as ICP above 30.
