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

The normal range for intracranial pressure (ICP) is recognized as being between 0 to 15 cm H2O. ICP is a critical measurement in assessing the status of patients with various neurological conditions, as excessive pressure within the skull can lead to brain injury. A normal ICP level indicates that there are no significant disturbances in the balance of cerebrospinal fluid, brain tissue, and blood volume, which is essential for maintaining adequate cerebral perfusion and function.

While values above this normal range indicate varying degrees of intracranial hypertension, understanding that normal ICP should not exceed 15 cm H2O is vital for prompt recognition and intervention in critical care settings. This knowledge is crucial for effective patient monitoring and management in conditions such as traumatic brain injury, strokes, or other scenarios where neurosurgical intervention may be required.
