Demonstration of a Non-Invasive ICP change Monitor

Abstract

The goal of the research is to design, build and demonstrate a device, which can be used on the battlefield, to diagnose blunt trauma injuries that can lead to increased intracranial pressure (ICP), and indicate the casualty's need for immediate treatment with drugs and evacuation to a facility equipped to handle brain trauma. The scope of the program described in this report involved fabrication and clinical testing of a device interfaced to laboratory data acquisition equipment with no realtime analysis software. Active Signal designed and fabricated the non-invasive lop (NICP) monitor system and tested it on patients with ventriculostomies (pressure transduction of lop from the lateral ventricles) or fiberoptic extradural pressure monitors in the Neurotrauma Critical Care Unit of the R. Adams Cowley Shock Trauma Center (STC) at the University of Maryland. Nine patients were monitored and comparisons between the NICP system and manometry data were made in combination with the patients status and outcome. This testing demonstrated the feasibility of using the NICP system to monitor pressure elevation and also the viability of the normal cerebral compensation mechanisms.
