Abstract :
We present a novel technique for recording and extracting brain auditory evoked potential (BAEP) under hypoxic conditions. We studied the effects of hyperventilation followed by oxygen depletion with electroencephalography (EEG) and BAEP. Our results show that BAEPs can be extracted and analyzed under hypoxic conditions with minimum averaging (400 realizations) allowing real time evaluation of the auditory pathway. This noninvasive technique can be readily extended to evaluation in patients with cerebrospinal injury.
