What is ICP? What are the s/s?

Intracranial pressure is the pressure inside the skull, resulting from the balance of brain tissue, cerebrospinal fluid, and blood. When ICP rises, it can squeeze brain tissue and impair cerebral perfusion, leading to rapid neurologic decline. Typical signs include headache, vomiting, and altered mental status, as the brain responds to the increasing pressure. Unequal pupils can occur from pressure effects on the oculomotor nerve, and Cushing's triad—hypertension with a widening pulse pressure, bradycardia, and irregular respirations—signals impending brain herniation and is a late, dangerous indicator. In prolonged elevation, papilledema may be seen on exam. Other options miss the essential concept: measuring ICP relates to brain pressure, not blood sugar, and fever is not a hallmark of ICP. An option stating ICP is not clinically relevant is inaccurate, since elevated ICP is a critical neuro emergency.
