    摘要： An exemplary monitoring system 1) receives a user input command to begin monitoring evoked responses that occur in response to acoustic stimulation during an insertion procedure in which a lead that is communicatively coupled to a cochlear implant is inserted into a cochlea of a patient, the lead having an array of intracochlear electrodes and an extracochlear electrode, the extracochlear electrode physically and communicatively coupled to a probe that is also communicatively coupled to the monitoring system, 2) directs, in response to the user input command, the cochlear implant to short an intracochlear electrode with the extracochlear electrode, 3) presents the acoustic stimulation to the patient, and 4) records the evoked responses that occur in response to the acoustic stimulation by using the intracochlear electrode to detect signals representative of the evoked responses and receiving the detected signals by way of the extracochlear electrode and the probe.
