The pressure in the cranial vault is measured in millimeters of mercury (mm Hg) and is normally less than 20 mm Hg. The cranium, composed of the blood, cerebrospinal fluid, and the brain, is extremely rigid and cannot accommodate large volume increases. Any increase in the volume of its contents will increase the pressure within the cranial vault. An increase in the volume of one component will result in a decrease in volume in one or two of the other components. For example, the clinical implication of an increase in CSF volume is a decrease in cerebral blood flow or herniation of the brain, a potentially life-threatening complication.
clear and exactly what is needed from subfalcine herniation. continue to provide these great lectures!
exactly what needs to be understood about intracranial pressure. clear and easily understood
Just reading from the slide not explaining anything at all. Could really use some illustrations to differentiate the different types of brain herniation.
Lecture was excellent! very clear and simple. I enjoyed it. Thanks so much Dr Raj.
