MEASUREMENT OF CEREBRAL PHYSIOLOGIC PARAMETERS USING BIOIMPEDANCE

摘要

Devices and methods are disclosed for detecting and/or monitoring cerebral pathologies. In one embodiment, a cerebro-hemodynamic measurement apparatus is disclosed that includes at least one processor. The at least one processor is configured to receive, via at least one sensor, at least one signal associated with a brain of a subject. The at least one processor is configured to determine, based on the at least one signal, a change in cerebral blood volume caused by a cardiac pulsation. The at least one processor is configured to determine, based on the at least one signal, a change in intracranial pressure due to cardiac pulsation. The at least one processor is also configured to estimate mean intracranial pressure based on changes in the cerebral blood volume, changes in the intracranial pressure, and a compliance indicator.
