786:, because the damage herniation can cause is so severe that it may be worthwhile to constrict blood vessels even if doing so reduces blood flow. ICP can also be lowered by raising the head of the bed, improving venous drainage. A side effect of this is that it could lower pressure of blood to the head, resulting in a reduced and possibly inadequate blood supply to the brain. Venous drainage may also be impeded by external factors such as hard collars to immobilize the neck in trauma patients, and this may also increase the ICP. Sandbags may be used to further limit neck movement. 782:, but the induced constriction of blood vessels limits blood flow to the brain at a time when the brain may already be ischemic—hence it is no longer widely used. Furthermore, the brain adjusts to the new level of carbon dioxide after 48 to 72 hours of hyperventilation, which could cause the vessels to rapidly dilate if carbon-dioxide levels were returned to normal too quickly. Hyperventilation is still used if ICP is resistant to other methods of control, or there are signs of 579:
a temporal relation to the low CSF pressure or leakage and the headache cannot be better explained by another ICHD diagnosis. The final criteria is that in the rare cases of spontaneous intracranial hypotension with no headache present, the neurologic symptoms that are present must be attributable to low CSF or explained by the diagnosis of spontaneous intracranial hypotension.

The International Classification of Headache Disorders (ICHD) Third Edition diagnostic criteria for spontaneous intracranial hypotension includes any headache attributed to low CSF pressure (low CSF opening pressure) or CSF leakage (evidence of CSF leakage on imaging). Further, the headache must have

The principal buffers for increased volumes include CSF and, to a lesser extent, blood volume. These buffers respond to increases in volume of the remaining intracranial constituents. For example, an increase in lesion volume (e.g., epidural hematoma) will be compensated by the downward displacement

The Monro–Kellie hypothesis states that the cranial compartment is inelastic and that the volume inside the cranium is fixed.

This results in widespread reduction in cerebral flow and perfusion, eventually leading to ischemia and brain infarction. Increased blood pressure can also make 887:. The section of bone removed, known as a bone flap, can be stored in the patient's abdomen and resited back to complete the skull once the acute cause of raised ICP's has resolved.

Although the exact mechanism is unknown, current research shows that dexamethasone is capable of decreasing peritumoral water content and local tissue pressure to decrease ICP. 151:
