title: Effect of hemorrhagic hypotension on blood flow to the basal and upper turns of the cochlea.
abstract: The effect of hemorrhagic hypotension on blood flow in the cochlea was studied in guinea pigs. Using two laser Doppler probes, simultaneous measurements were made from the basal and upper turns of the cochlea. Hypotension induced by removal of blood resulted in reduction of cochlear blood flow. Cochlear blood flow, however, did not reduce the same extent as the extent of hypotension and the reduction of blood flow was observed to be more remarkable in the upper turns than in the basal turn.
