Multigas
22-17
Waveform Display
Adjusting Waveform Size
The CO
2
waveform can appear on your monitor in any of three scale sizes: 0 to
80 mmHg, 0 to 60 mmHg or 0 to 40 mmHg (0 to 10.0 kPa, 0 to 7.5 kPa, or 0 to
5.0 kPa).
Turning the Waveform Display Off
To reduce display clutter, the multigas waveform can be turned off while leaving
the numerics visible. When the waveform is off, the size adjustment, sweep
speed, and freeze keys are disabled.
Selecting a Sweep Speed
You can view this waveform at any of the following sweep speeds: 25, 12.5, 6.25,
3.12, or 1.56 mm/second.
Freezing the Waveform
You can freeze the gas waveform display at any time. The waveform stays frozen
until you press the FREEZE ON/OFF key again or until you press the NORMAL
SCREEN key. When the waveform is frozen, the SIZE key in the SETUP menu is
disabled.
Selecting a Text Format
You can change display formats for multigas by switching between large and
small text (refer to Display Detail on page 22-12).
Small text allows clear visualization of the waveform. However, It is recommended
that large text be used for routine monitoring.
Selecting a Unit of Measure
You can monitor CO
2
values as a percentage (%), as millimeters of mercury
(mmHg) or kilo Pascal (kPa). If you want to use % as the measurement, press the
PERCENT/mmHg (kPa) key until PERCENT is highlighted. If you want to
measure in mmHg (kPa), press the PERCENT/mmHg (kPa) key until mmHg (kPa)
is highlighted.
