Intracranial hypertension

Intracranial pressure refers to the pressure produced by the contents of the cranial cavity on the wall of the cranial cavity. It is composed of two factors: hydrostatic pressure and vascular dynamic pressure. Because the total volume of the cranial cavity is relatively fixed, intracranial pressure remains relatively stable. Normal supine intracranial pressure is about 1.33kPa (10mmHg). Intracranial hypertension is called when the brain tissue is swollen, intracranial space-occupying lesions or excessive secretion of cerebral dorsal fluid, malabsorption, blocked circulation, or excessive cerebral blood perfusion cause intracranial pressure to remain above 2.0kPa (15mmHg). (Inreacranial hypertension).
