This may occur in patients with severe traumatic brain injury (TBI), aneurysmal subarachnoid hemorrhage, or intracerebral hemorrhage (ICH). Methods Cushing's Triad: What Is It, Causes, Assessment Findings - Osmosis Fluid surrounding the brain is constantly produced and reabsorbed, maintaining just enough intracranial pressure to help protect the brain if there is blunt head trauma. Elevated intracranial pressure (ICP) is frequent after traumatic brain injury (TBI) and may cause abnormal pupillary reactivity, which in turn is associated with a worse prognosis. buffet tables for dining room; the script breakeven guitar tutorial General Considerations Since the brain is enclosed in a rigid cranium, the free space to expand is minimal. Pupil changes are not an immediate assessment finding following a concussion; in fact, pupil changes are often a late sign of neurologic complications.
