CO
2
Analyzer
The CO
2
Analyzer allows for continuous
monitoring shown in a waveform indicating
the CO
2
concentration. A numerical
presentations of End Tidal CO
2
concentration (etCO
2
), CO
2
minute
elimination and CO
2
tidal elimination is also
shown on the screen. Alarm limits for high
and low etCO
2
can be individually set.
The CO
2
Analyzer processes data and
derives values for the following parameters:
Instantaneous CO
2
(Capnogram) – the
instantaneous value of the CO
2
level;
displayed on the screen as a waveform
depicting the variation in airway CO
2
level
during the patient’s respiration cycle.
End-tidal CO
2
(etCO
2
) – the level of CO
2
in
the airway at the end of expiration; normally
the maximum value measured over a
specified interval. The current value for
etCO
2
is displayed on the screen.
CO
2
minute elimination ( CO
2
) –
expressed in ml per minute indicates the
volume of expired CO
2
per minute.
CO
2
tidal elimination (VTCO
2
) – expressed
in ml per breath indicates the volume of
expired CO
2
per breath.
Note: CO
2
Minute elimination ( CO
2
) and
Tidal CO
2
elimination (VTCO
2
). Elimination of
CO
2
from the body takes place via expired
gas from the lung. Production of CO
2
takes
place in cellular compartments and body
tissues.
Cautions:
• 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.
• 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:
• The capnostat sensor and airway adapter
windows should be placed vertically to
reduce the possibility of optical
interference due to window contamination.
• If Servo Ultra Nebulizer and CO
2
Analyzer
are in use simultaneously. It may affect the
CO
2
readings.
• Only MAQUET airway adapter may be
used together with the Capnostat sensor.
