 As an intracranial mass expands within the bony cranium it can cause an increase in ICP. This increase in ICP can be offset by displacement of CSF, blood flow, and displacement of the brain matter.This effect does not continue, and once a certain point is reached, ICP can rise exponentially (see Figure 6.2).

 Sudden increases in ICP can increase the risk of brain herniation.

 During neuroanesthesia, steps are taken to reduce brain volume as much as possible to offset increases in ICP.

Figure 6.2 The effects of intracranial volume changes on intracranial pressure. At a certain point, the increase in intracranial volume causes a dramatic increase in intracranial pressure as compensatory mechanisms become exhausted.
