Switching Numerics On and Off
For some measurements, such as EEG, you can choose which numerics to view on the screen.
In the measurement's setup menu, select the numeric name to toggle between on and off.
For example in the
Setup EEG menu, select the EEG numeric name to toggle between on and off.
Adjusting a Measurement Wave
To quickly adjust wave-related measurement settings (such as speed or size), select the measurement
wave itself. This displays the measurement wave menu, which has only wave-related measurement
settings.
Changing Wave Speeds
Lowering the wave speed compresses the wave and lets you view a longer time period. Increasing the
speed expands the waveform, giving you a more detailed view.
The monitor distinguishes three groups of wave speed settings:
•
RespiratorySpeed, for all respiratory waves: CO
2
, anesthetic agents and O
2
• EEG Speed, for all EEG and BIS waves
•
Global Speed, for all waves not included in the other two groups.
Changing the Wave Group Speed
The wave speed group setting defines the speed of all the waves in the group.
To change the wave speed of a wave speed group,
1 Select Main Setup, then select User Interface
2 Select Global Speed, RespiratorySpeed, or EEG Speed as required
3 Select a value from the list of available speeds.
Changing Wave Speed for a Channel
To change the wave speed of an individual wave channel,
1 Enter the Wave menu for a measurement by selecting its wave.
2 Select Change Speed.
3 To set the speed to the wave group speed, select RespiratorySpeed, EEG Speed, or Global Speed.
To set an individual channel speed, select a numeric value from the list of available speeds. This
overrides the wave group speed setting and set the speed for the individual wave channel on the
monitor Screen. The wave channel speed is independent of the wave (label) depicted in the
channel, if you change the wave, the new wave will retain the set channel speed.
Freezing Waves
You can freeze waves on the screen and measure parts of the wave using cursors. The waves are frozen
with a history of 20 seconds so that you can go back and measure what you have seen.
