How much does the latency of BAER wave V increase for each degree Celsius drop in temperature?

The latency of the Brainstem Auditory Evoked Response (BAER) wave V is known to increase with a decrease in temperature. Specifically, the accepted change is a latency increase of 0.2 milliseconds for each degree Celsius drop in temperature. This relationship is significant in intraoperative monitoring, as hypothermia can affect the neural conduction velocity and thus alter the auditory evoked potentials. Understanding this connection is crucial for neurophysiologists monitoring patients during surgery, as it allows them to interpret changes in latency appropriately and determine whether those changes are related to body temperature shifts rather than neurological compromise.

The other options represent either an overestimation or underestimation of this latency change, demonstrating the importance of precise values in neurophysiological measurements.
