Operation (5-Lead, 5L, LT and XG) Operation (XG)
5. Connect a disc filter (optional), nafion tubing (optional-recommended for high humidity
situations), and nasal cannula to the patient side of the airway adapter. This is the side
that has the Capnostat® name.
NOTE: Ensure all tubing connections are secure. Ensure that the
nasal cannula is away from all sources of CO
2
(including the
patient’s and your own exhaled breath and ventilator
exhaust valves).
NOTE: Connecting the optional disc filter and tubing is
recommended when high humidity exists or during lengthy
monitoring periods. However, to maintain specified
accuracy for breath rates over 50, the disc filter should be
removed.
6.
Press the CO
2
PUMP key (12), then the SELECT key (2), to turn the sampling pump on
and to initiate a pump calibration. When the pump calibration is complete, the message
“CO
2
: Pump Cal Complete” displays. See “Sidestream CO
2
Messages (on Passports
with Sidestream CO
2
only)” on page 1-164 for additional CO
2
messages.
NOTE: This pump calibration also calibrates the adapter. It is not
necessary to perform a separate adapter calibration at this
time.
7.
After the pump calibration is complete, place the nasal cannula on the patient.
8. When the Passport XG has detected valid breaths, numbers will display for ETCO
2
,
Inspired CO
2
and Respiratory Rate (if enabled for CO
2
as source).
9. If not already set, use the Setup Menu, to select “Auto Display CO
2
”waveform to be
displayed on Waveform 2 or Waveform 3.
10. If desired, the CO
2
waveform scale can be changed by entering the CO
2
menu. See
“Use of Menus” on page 1-109” for details. The CO
2
menu also has provisions for N
2
O
and O
2
compensation.
NOTE: See “User Configuration Mode” on page 1-153 for
Barometric Pressure and CO
2
Units selection. On units with
sidesteam CO
2
capability, there is automatic compensation
for barometric pressure.
NOTE: See “Sidestream CO
2
Messages (on Passports with
Sidestream CO
2
only)” on page 1-164 for more details on

1.6.13.2 Sequence for Establishing Sidestream Capnostat® CO
2
for
Intubated Patients
WARNING: In an intubated configuration, ensure all tubing connections
are tight. If tubing disconnects on the monitor side of the
airway adapter, ventilator pressures cause inaccurate CO
2
waveforms and readouts to be displayed.
When Sidestream is used to monitor CO
2
in an intubated configuration, the aspired gas
within the intubation line is sampled and used to measure the CO
2
level. This setup
procedure is described below.
1. Plug the Capnostat® CO
2
sensor into the Passport XG CO
2
connector (34). The “CO
2
:
Sensor Warming Up” message is displayed. The CO
2
numeric dataand waveform will
not be available until the “CO
2
: Sensor Warming Up” message disappears.
