What does intracranial pressure (ICP) refer to?

Intracranial pressure (ICP) specifically refers to the pressure within the cranial cavity, which houses the brain, blood vessels, and cerebrospinal fluid (CSF). This pressure is crucial for maintaining the delicate balance of these components, as changes can indicate medical conditions that may require prompt intervention. ICP plays a vital role in assessing and monitoring conditions like traumatic brain injury, hydrocephalus, and other neurological disorders.

Understanding ICP is essential for healthcare professionals, as abnormal levels can lead to serious complications, including brain herniation, reduced blood flow, and even death. Monitoring ICP helps in managing and guiding treatments for patients with conditions that affect the brain's environment.
