Evaluation of Near Infrared Spectroscopy in Patients with Traumatic Brain Injury
Near infrared spectroscopy provides a continuous noninvasive measure of changes in regional cerebral oxygen (rSO2) and quantifies these changes into a single index (Somanetics, Corporation). McCormick et al1 originally validated this index from gas analysis studies of normal adults where they found that the rSO2 index represented a summation of differential weighting of arterial O2 saturation (SaO2) (20%), jugular venous O2 saturation (SvjO2) (75%), and extracranial O2 saturation (5%).
