What does intracranial pressure (ICP) measure?

Intracranial pressure (ICP) specifically refers to the pressure inside the skull, which encompasses the brain, cerebrospinal fluid, and blood. Elevated ICP can indicate several medical conditions, such as traumatic brain injury, brain tumors, or cerebral edema, and it is crucial for EMTs and healthcare professionals to understand because it can have significant implications for patient management and outcomes. Accurate measurement and monitoring of ICP can help guide treatments and interventions in critical care settings. The other options do not pertain to the cranium, making them unrelated to ICP specifically.
