Abstract
An intracranial pressure (ICP) monitoring system and method for using such is disclosed. The system stimulates and interprets predictable external effects of elevated ICP. In one embodiment, the system non-invasively and continuously monitors ICP by stimulating and interpreting predictable changes measured in the otoacoustic emission (OAE) signal of the patient. The system may alternately non-invasively and continuously monitor ICP by stimulating, measuring, and interpreting other responses which rely on the transmission of vibrations through the middle ear cochlear interface, such as tympanograms (TGRAMs), ocular-acoustic reflex, auditory brainstem response (ABR), or cochlear microphonics.
