Goes down.
Hyperventilation "blows off" carbon dioxide (CO2), lowering the blood CO2 levels; this causes vasoconstriction (narrowing of the blood vessels) resulting in a lower blood volume in the brain and a slight drop in intracranial pressure.
It is a temporary measure, however, and even though it lowers intracranial pressure it may make brain injury worse, because it reduces cerebral perfusion (the flow of blood to the brain.)

Are there any famous people associated with Intracanial pressure?
Raised intracranial pressure is a relatively common problem facing the clinician treating neurocritically ill patients. It is a leading cause of death in patients with intracranial pathology. There is a lack of controlled clinical trials evaluating most of the therapies currently available for raised intracranial pressure. The basic pathophysiologic and clinical principles of raised intracranial pressure are discussed and the major treatment options are presented. Patients with raised intracranial pressure should be evaluated immediately with particular attention to airway and hemodynamic status. Controlled hyperventilation and hyperosmolality (using mannitol or hypertonic saline solutions) frequently are administered simultaneously. In patients with refractory elevation of intracranial pressure other therapies such as barbiturate coma and surgical interventions are available....so, NOPE!

Pneumocrania is Pneumocephalus ... The presence of air in the intracranial cavity.
What is the typical change in blood pressure with increased intracranial pressure?
inreasing pressure
Does mannitol increase intracranial pressure?
No, it decreases it
What does pressure on the emetic center cause with increased intracranial pressure?
vomiting
What are late signs of increased intracranial pressure?
A widened pulse pressure
What is Mannitol medication administration?
to decrease the intracranial pressure
How might the fontanels be used to estimate intracranial pressure?
If they are sunken, then the patient may have a low ICP (intracranial pressure), if they are normal then it is likely normal, and if they are bulging then it is likely that it is high.
