Intracranial pressure (ICP) refers to the pressure inside the skull, which contains the brain, blood, and cerebrospinal fluid. This pressure is crucial for maintaining the brain's health and function. Normal ICP ranges from 7 to 15 mmHg in adults. Elevated ICP can occur due to various conditions, such as head injuries, brain tumors, or infections, and can lead to serious complications if not addressed. Monitoring ICP is essential in medical settings, especially for patients with severe head trauma or neurological disorders. Symptoms of increased ICP may include headaches, nausea, vomiting, and altered consciousness. Timely intervention can help prevent damage to the brain and improve patient outcomes.
