<unk>  pressure, (ICP), is the pressure exerted by three structures inside the cranium; brain parenchyma, CSF and blood. The norma ICP is 10-15 mmHg and is usually maintained by equilibrium of the<unk>  contents.<unk><unk>  ( IH), is elevation of the pressure in the cranium. It typically occurs when the ICP is >20 mmHg. Hans Queckenstedt's was the first person to use lumbar needle for ICP monitoring.<unk><unk>  is generally categorized as acute or chronic. The Monro-Kellie hypothesis explains the relationship between the contents of the cranium and<unk>  pressure. It explains the underlying pathophysiology of elevated<unk>  pressure or<unk><unk> . Several pathophysiologic mechanisms are thought to be involved in the pathogenesis of Increased<unk>  pressure (ICP) or<unk><unk>  (ICH). All mechanisms eventually lead to brain injury from brain stem compression and decreased cerebral blood supply or ischemia. Increased<unk>  pressure (ICP) or<unk><unk>  (ICH) must be differentiated from other diseases that cause headache, nausea, vomiting and neurologic deficits such as tumor, abscess or space occupying lesion, venous sinus thrombosis, neck surgery, Obstructive hydrocephalus, meningitis, subarachnoid hemorrhage, choroid plexus papilloma, and Malignant systemic<unk> . The diagnosis of Increased<unk>  pressure (ICP) or<unk><unk>  (ICH) is made when ICP is >20 mmHg. CT scan or MRI may be considered initial diagnostic investigations.<unk><unk>  is considered to be emergency condition.  Treatment includes resuscitative measures and specific directed therapy.  Resuscitative measures include oxygen, blood pressure and ICP monitoring, osmotic diuresis, head elevation up to 30 degrees, therapeutic hypothermia and seizure prophylaxis.
