What problem may arise from using compressible tubing during intraoperative BAERs?

Using compressible tubing during intraoperative Brainstem Auditory Evoked Responses (BAERs) can lead to significant issues, particularly related to sound transmission. Compressible tubing is designed to change shape under pressure, which can result in obstruction or constriction of the luminal space. When sound is transmitted through this kind of tubing, it is essential that the path remains clear to deliver accurate auditory stimuli to the ear. If the compressible tubing becomes obstructed, the sound may not reach the ear effectively, potentially leading to incorrect or ambiguous BAER results.

Maintaining clear and open tubing is critical for the integrity of the auditory signals being monitored during surgery. Any obstruction could lead to misinterpretation of the patient's functional auditory responses, making it challenging for the surgical team to assess auditory pathways accurately. Thus, it is crucial that non-compressible, rigid tubing is used to ensure reliable sound transmission during intraoperative monitoring sessions.
