•
With the system fully assembled, the sound processor locked to the implant, and the sterile
insert placed in the ear canal, click "Start" to begin the ECochG measurement.
•
Acoustic stimulation parameters are displayed on the ECochG Insertion screen. These
values can be modified in settings when not making an ECochG measurement.
•
Use the blue markers at the bottom of the screen to annotate the measurements
as desired.
o
Note can be clicked on to add a custom note.
•
Click "Stop" to end the ECochG Insertion measurement.
•
Click "Next" to advance to the Electrode Sweep or use the navigation panel to select the
desired measurement.
During ECochG Insertion a Waveform Monitor may be used to provide the surgeon
with awareness of the cochlear microphonic amplitude during electrode insertion.
•
The Waveform Monitor may be turned on or off by navigating to the ECochG portion of
the settings and turning the audio on or off.
•
User may adjust the value for an Event Threshold, in units of dB, for the change in the
amplitude of the cochlear microphonic that they would like to be alerted to. When the
Event Threshold is exceeded a "knocking" sound will be played by the system.
•
The minimum response amplitude may be adjusted and below this value the system will
play a steady low-pitched noise to indicate that the system is operating, but the specified
amplitude has not been exceeded.
•
The maximum response amplitude may be adjusted and above this value the system will
play a steady high-pitched noise to indicate that the system is operating and the amplitude
is above the specified maximum.
•
Between the minimum response amplitude and the maximum response amplitude
the system will play sounds of increasing pitch to indicate the amplitude of the
cochlear microphonic.
o
As the cochlear microphonic amplitude increases the waveform monitor will play sounds
like going up a musical scale.
o
If the cochlear microphonic amplitude decreases, the waveform monitor will play sounds
like going down a musical scale.
o
If the Event Threshold is exceeded, the system will immediately play the "knocking"
sound to alert the user. Afterwards, sounds will be played corresponding to the
amplitude of the cochlear microphonic.
