8.2 CO
2
Analyzer
When the CO
2
Analyzer is in use, the
following data is displayed on the screen:
• CO
2
concentration vs. time (waveform)
• End Tidal CO
2
concentration (etCO
2
)
• CO
2
minute elimination
• CO
2
tidal elimination
Note:
Alarm limits for high and low etCO
2
can be individually set.
Important: If the upper alarm limit is set
above the maximum measuring range, no
alarm will be activated even if the upper
limit is exceeded.
Important: If a nebulizer and CO
2
Analyzer
are in use simultaneously, the CO
2
reading
may be affected.
8.2.1 CO
2
Analyzer Use Guidelines
These guidelines are reminders for health
care professionals who have already been
trained to use the CO
2
Analyzer:
• The capnostat sensor and airway adapter
windows should be placed vertically to
reduce the possibility of optical
interference due to window
contamination.
• Do not insert two CO
2
modules at the
same time. The Servo-i Ventilator System
can only handle one CO
2
module at a
time.
• Use only a MAQUET airway adapter with
the capnostat sensor.
8.2.2 CO
2
Analyzer Components
1. Gas flow through the airway adapter in
the capnostat sensor.
2. The sensor uses a solid state and IR
based optical system with no moveable
parts. It measures the difference
between a reference light beam and
one filtered for CO
2
wave lengths.
8.2.3 CO
2
Analyzer Calibration
Before beginning the calibration procedure
make sure the capnostat sensor is warm.
Values displayed during warm-up have
reduced accuracy. If calibration is needed, a
message will appear.
There are two calibration options: cell zero
and verification (see later in this section).
To calibrate the CO
2
Analyzer:
1. Press the fixed key Menu .
2. Press the Options touchpad.
3. Press the CO
2
calibration touchpad.
4. Press the Cell zero touchpad if the
capnostat sensor has been shifted.
5. Press the
Verification
touchpad to
perform a calibration including cell
zeroing, verification against reference
cell, and adapter zeroing.
Important:
Verification calibration is
recommended. Always perform a
verification when the airway adapter is
altered, a faulty capnostat sensor is
suspected, or the system requests
calibration.
