Intracranial pressure is the pressure inside your skull. It can be measured with an:
- Intraventricular catheter: A tube inserted through a hole in the skull into an area of the brain that contains cerebrospinal fluid
- Subdural screw: A hollow screw inserted through the membrane that protects the brain and spinal cord
- Epidural sensor: A less-invasive method that uses a sensor put between the skull and brain
Intracranial pressure monitoring is usually done on people who have neurological emergencies, such as a severe head injury.
