• Locate the adapter onto the sensor (a click will be heard when both devices are
attached).
• Place one end of the adapter into the Y piece of the respiratory circuit. The other
end is reserved for the connection of the final step of the patient circuit.
• Place the cable connector of the capnograph in the ventilator as shown in the right
Fig. 14-1.
By connecting the capnograph to the ventilator, a warm up period of the sensor be-
gins. When this ends, a message saying ‘SENSOR OK’ will appear on the screen.
During the heating period, abnormal shifts of the CO
2
curves can be observed and
warning signals of low CO
2
may be triggered. These situations disappear when the
sensor warm up finishes.
Access to the CAPNOGRAPHY screen is achieved by pressing the [Graphics] key
and selecting the CO
2
screen.
On the
CAPNOGRAPHY
screen, it is possible to display the following curves in a
continuous form:
• PCO
2
vs. Time (under the pressure, volume and flow curves).
• Volumetric capnography (on the right, below the box showing the monitored para -
meters).
iTernIS ADV
allows continuous monitoring of these parameters on the Capnogra-
phy screen:
• ETCO
2
: partial pressure of CO
2
at the end of exhalation.
• Ratio VD/ VT: ratio of dead space and tidal volume.
• Serial dead space (VD): physiological dead space (anat alveolar).
• Current alveolar volume (AV): volume reaching the alveoli with each breath.
• Alveolar minute volume (Va min): volume reaching the alveoli every minute.
• Current volume of CO
2
: volume of CO
2
contained in every expiration.
• Elimination of CO
2
(VCO
2
): volume of CO
2
expirated per minute.
• PeCO
2
: partial pressure of CO
2
of the expirated gas mixture (alveolar gas + gases
of anatomical dead space).
