Which components can change to adapt to small increases in intracranial pressure?Intra- cranial blood (especially in the venous compartment) and CSF are the two components whose vol- ume can adapt most easily to accommodate an increase in the volume of intracranial contents.
What are the 3 components that impact intracranial pressure?Causes of ICP: Too much cerebrospinal fluid (the fluid around your brain and spinal cord) Bleeding into the brain. Swelling in the brain.
How does the body try to compensate for increased intracranial pressure?Because there's limited space for expansion in the skull, an increase in any of the components causes a change in ICP. Compensation typically occurs by displacing or shifting CSF, increasing the absorption of CSF, or decreasing cerebral blood flow. Without these changes, ICP will rise.
What structures are involved in increased intracranial tension?Since the skull is considered an unchangeable volume, any increase in the volume of components within the skull or an addition of a pathologic element will result in increased pressure within the skull. Pathologic structures that can cause increased ICP may include mass lesions, abscesses, and hematomas.
