The normal range for intracranial pressure (ICP) is 5 – 15mmHg. The average intracranial volume is 1700ml (composed of the brain 1400ml + CSF 150ml + blood 150ml), with Cerebrospinal Fluid (CSF) production around 500 – 600ml per day.

The skull is a rigid compartment, and the Monro-Kellie doctrine[1] describes a pressure-volume relationship, a dynamic equilibrium among components within the rigid skull compartment:

VIntracranial = VBrain + VCSF + VBlood

In order to protect the brain, the blood and CSF volume can be comprised as the primary protection. However, this mechanism can be overcome with large increases to these volumes.

This article discusses the importance of ICP monitoring and how it can be performed.
