Objective: Monitoring of cerebrovascular pressure reactivity (PRx) has diagnostic and prognostic value in head injured patients but needs invasive monitoring of intracranial pressure (ICP). Near infrared spectroscopy (NIRS) is a non-invasive modality, suitable for the continuous detection of cerebral[for full text, please go to the a.m. URL]
