Increased intracranial pressure is a serious medical condition that occurs when there is too much pressure within the skull from the brain, blood, or cerebrospinal fluid. This excess pressure can damage the brain by restricting blood flow or pressing on important structures. Common causes include bleeding or swelling in the brain or fluid surrounding it. If left untreated, increased ICP can lead to herniation, a fatal event where brain tissue is shifted through openings in the skull. Treatment aims to lower pressure through reducing swelling, maintaining adequate blood flow to the brain, lowering CSF and blood volumes, and controlling metabolic demands on the brain. Monitoring ICP via intracranial catheter allows for early detection and evaluation of treatment effectiveness in this
