Nerve Integrity Monitor
The following settings are available on the Nervassure EMG audio panel:
• Nervassure EMG audio - Mute the Nervassure EMG Audio using the selection option. If the user turns o the toggle button and
selects the Mute check box, then the system mutes the EMG audio for the sweeps initiated by a Nervassure stimulation pulse. If
the user turns on the toggle button (on is the default) and deselects the Mute check box, then the volume of the EMG audio for
Nervassure sweeps is controlled by the [+] and [-], or the slider bar.
• Voice - Nervassure values - if the user selects this toggle button check box, then the NIM periodically announces the last
Nervassure EMG value audibly. Use the drop-down menu to select the frequency of annunciation. Note: Voice – the user
cannot enable Stimulated EMG Values at the same time as Voice – Nervassure values. Therefore, when the user enables Voice –
Nervassure, the system automatically disables Voice – Stimulated EMG Values (found in Settings/Audio).

from their dropdown boxes:
— Slow rate
