What is the normal range for intracranial pressure (ICP)?

The normal range for intracranial pressure (ICP) is 0-15 mm Hg. This range is critical for assessing brain health and function, as elevated ICP can lead to serious complications, including brain herniation and damage to neuronal tissue. Maintaining ICP within this range is essential for ensuring adequate cerebral perfusion and preventing ischemia.

Within this normal range, the body is capable of regulating the pressure through various mechanisms, such as the absorption and production of cerebrospinal fluid (CSF), while also accommodating fluctuations that occur due to normal physiological activities. Monitoring ICP is a vital part of critical care, especially in patients who may have head injuries or other conditions affecting the brain.
