Prospective Evaluation of the Non-invasive ICP HeadSense Monitor in TBI Patients Undergoing Invasive ICP Monitoring

Patients with severe traumatic brain injury (TBI) are admitted to the intensive care unit (ICU). Under certain condition (such as a impaired consciousness) the intracranial pressure (ICP) is measured. An increase in the intracranial pressure might suggest secondary neurological deterioration and is considered an alarming symptom. Current practice is to insert an invasive monitor through a burr hole in the skull with the risk of bleeding and infection. Using a new type of ICP monitor (HeadSense) it is possible to measure ICP non-invasively through an acoustic signal.
