Mindray BeneVision N Series User Manual

27 - 10 BeneVision N Series Patient Monitor Operator’s Manual
From the CSA view you can select the following items:
■ EEG Channels
■ Parameters
■ Trend Length
To change Power Scale and CSA Clip setting, select CSA Setup.
■ Changing Power Scale can adjust the amplitude of spectral lines. The wider the power scale range, the
greater amplitude of the spectral lines is.
■ If CSA Clipping is switched on, the latest spectral line displays in a normal shape, in which area other go-
through spectral lines will be cut out. If the CSA Clipping is switched off, all the spectral lines display
normally.
27.9.2 DSA View
The Density Spectral Array (DSA) is to show changes in the power spectrum distribution over time.
To display the DSA View, follow this procedure:
1. Select the EEG numerics area or waveform area to enter the EEG menu.
2. From the bottom of the EEG menu, select EEG Expand.
3. Select the DSA tab.
The DSA View provides up to DSA of four EEG channels. It provides the following information:
From the DSA view you can select the following items:
■ EEG Channels
■ Parameters
■ Trend Length
■ Power Scale
Displayed item Description
Color bar It is located at the right of the DSA view. The color bar color codes the power.
You can change the setting of
Power Scale to adjust the color of
corresponding power.
Status bar Displays the current montage, filter setting, notch frequency, SEF percentage
(95%), and trendline labels and color codes.
Frequency scale It is the vertical axis. The scale range depends on the filter settings (
Low Freq
Cut-off
and High Freq Cut-off setting. The maximum displayed frequency is
30 Hz, so if you set
High Freq Cut-off to 50 or 70, the upper scale remains 30.
Trend lines EEG values are sampled at configured time intervals and displayed as color-
coded trendlines. Trendlines are available for up to three frequency numerics
(SEF, MF, and PPF). SEF trendline is white, MF trendline is purple, and PPF
trendline is green.
“?” mark Appears when high electrode impedance or artifact is detected, electrodes
are off or disconnected is changed.
