Cranial perfusion pressure
WebPrevious investigations have suggested that intracranial pressure waves may be induced by reduction of cerebral perfusion pressure (CPP). Since pressure waves were noted … WebOct 6, 2024 · In moderate and severe TBI, intracranial pressure (ICP) elevation from brain swelling or bleeding may lead to significant brain injury or death. Clinical management entails measures to lower ICP, but ICP-based therapy requires invasive ICP probes that carry risk of infection and bleeding, and can only be administered in hospital settings.
