What is cerebral compliance?
Regarding this, what is intracranial compliance?
Intracranial compliance (ICC) represents the change in volume (ΔV) per unit change in pressure (ΔP), and is exactly the inverse of elastance. In other words, ICC determines the ability of the intracranial compartment to accommodate an increase in volume without a large increase in intracranial pressure (ICP).
Similarly, how is intracranial pressure maintained? The body has various mechanisms by which it keeps the ICP stable, with CSF pressures varying by about 1 mmHg in normal adults through shifts in production and absorption of CSF. Changes in ICP are attributed to volume changes in one or more of the constituents contained in the cranium.
One may also ask, what is the normal range for cerebral perfusion pressure?
Normal CPP lies between 60 and 80 mm Hg, but these values can shift to the left or right depending on individual patient physiology.
How does the brain compensate for increased ICP?
CSF plays an important role in compensating for increases in ICP by 'spatial compensation' whereby an increase in the volume of an intracranial constituent will cause a decrease in intracranial CSF volume by displacing CSF into the spinal canal.
