Operation (5-Lead, 5L, LT and XG) Operation (XG)
2. Select CO
2
/Off or CO
2
/ECG as the Resp. Source in the Resp Menu.
3. Snap a clean airway adapter into the U-shaped sensor. Align the arrow on the bottom of
the adapter with the arrow on the bottom of the sensor.
4.
Position the airway adapter between the endotracheal tube and the Y-piece of the
breathing circuit.
5. When the Passport XG has detected valid breaths, numeric data will display for ETCO
2
,
Inspired CO
2
and Respiratory Rate.
6.
Using the Setup Menu, select the “Auto Display CO
2
” waveform to be displayed on
Waveform 2 or Waveform 3.
7. 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.
NOTE: See “CO
2
Messages (only units equipped with Capnostat
CO
2
)” on page 1-162 for more details on messages.
1.6.12.2 Adapter Calibration
Adapter calibration compensates for the optical differences between the adult and neonatal
airway adapters for mainstream CO
2
operation.
Adapter calibration needs to be performed each time the type of airway adapter is switched.
For example: if switching from using a re-usable adult to a neonatal or neonatal to a re-
usable adult adapter, a calibration is needed (not if switching from a re-usable adult adapter
to another re-usable adult adapter). Adapter calibration should also be performed if the
message “Check Adapter” displays.
NOTE: In order to perform an accurate adapter calibration, the
“Sensor Warming Up” message must not be displayed.
To perform an adapter calibration:
1. Place the sensor and airway adapter away from all sources of CO
2
(including
the patient’s and your own exhaled breath, and ventilator exhaust valves).
2. Choose Start Adapter Cal - Yes from the CO
2
menu. (See “Use of Menus” on page 1-
109.)
NOTE: If the monitor detects changing CO
2
levels (breaths) during
an adapter calibration, a “Breaths Detected ... Retry”
message displays, and then an “Adapter Cal Failure”
message will display. Remove the source of CO
2
and repeat
the calibration.
