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

The normal range for intracranial pressure (ICP) is between 10 and 15 mmHg. This range indicates that the pressure within the cranial cavity is maintained at levels that allow for proper brain function while also accommodating the volume of cerebrospinal fluid and blood flow. ICP values outside this range may signal potential neurological issues; for instance, significant increases in ICP may suggest conditions such as traumatic brain injury, hydrocephalus, or brain tumors.

Though the ranges provided in the incorrect answers also mention pressures that can occur under various conditions, they do not accurately reflect the normal physiological range for ICP. Values lower than 10 mmHg may be indicative of abnormal conditions, while pressures exceeding 15 mmHg are often cause for concern and may necessitate clinical intervention. Understanding the normal values for ICP helps clinicians monitor and manage patients effectively in critical care settings.
