Correlation between cerebral co-oximetry (rSO2) and outcomes in traumatic brain injury cases: A prospective, observational study.

Background: Traumatic brain injury (TBI) is known to be an important reason for the increase in disabilities and deaths worldwide. Studies have demonstrated that brain tissue oxygen (PO2) monitoring reduces mortality significantly but is a invasive method of monitoring. Therefore, there is a need to monitor cerebral ischemia in TBI by noninvasive methods.
