Intracranial Hypertension (IH)
What is Intracranial Hypertension?
Intracranial pressure (ICP) is the pressure inside the skull. In otherwords, the brain tissue and cerebrospinal fluid (CSF). Different mechanisms in the body keep the intracranial pressure stable. CSF pressure has been shown to be influenced by abrupt changes in intrathoracic pressure during coughing, valsalva,and communication with the venous and arterial systems.
Very high intracranial pressures are usually fatal if prolonged. An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation (Chiari Malformation), and restrict blood supply to the brain.
