Figure 24 - Smoothing Rate
The BIS VISTA system offers three choices of smoothing rates over which the BIS value is
averaged:
• 10 seconds: Provides increased responsiveness to state changes, such as induction or
awakening. This is the default setting for Monitor Mode III.
• 15 seconds: This is the default setting for Monitor Modes I and IV.
• 30 seconds: Provides a smoother trend with decreased variability and sensitivity to
artifact. This is the default setting for Monitor Mode II.
To change the Smoothing Rate, press the [BIS Smoothing Rate] touch key. The current
Smoothing Rate displays in green letters. Press the key until the desired rate displays in
green. Press [HOME] to exit.
To permanently save this change, press the [View/Save Settings] touch key in the menu
system, then press [Save Active].
