1.3.11.1 Sequence for Establishing Capnostat CO
2
1. Plug the CO
2
sensor into the Passport connector. The “Sensor Warming Up” message is
displayed.
2.
Select CO
2
as the Resp. Source in the Setup Menu.
3. Snap a clean airway adapter into the U-shaped sensor. Align the line on the bottom of
the adapter with the line on the bottom of the sensor.
4. Position the airway adapter between the endotracheal tube and the Y-piece of the
breathing circuit.
5. After the Passport has detected valid breaths, it will display numbers for ETCO
2
, Inspired
CO
2
and Respiratory Rate.
6. Select the CO
2
waveform to be displayed on Waveform 2 or Waveform 3 using the
Setup Menu.
7. If desired the CO
2
waveform scale can be changed by entering the CO
2
menu. See
Section 1.3.4, “Use of Menus” for details.
8. The CO
2
menu also has provisions for N
2
O and O
2
compensation.
NOTE: See “User Configuration Mode” on page 53 for Barometric
Pressure and CO
2
Units selection.
NOTE: See “CO
2
Messages (only units equipped with Capnostat
CO
2
)” on page 60 for more details on messages.
1.3.11.2 Adapter Calibration
Adapter calibration compensates for the optical differences between the adult and neonatal
airway adapters.
Adapter calibration needs to be performed each time the type of airway adapter is switched.
For example: if switching from using an adult to a neonatal or neonatal to an adult adapter a
calibration is needed (not if switching from an adult adapter to another adult adapter).
Adapter calibration should also be performed if the message “Check Adapter” displays.
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 23.)
NOTE: If the monitor detects changing CO
2
levels (breaths) during
an adapter calibration, an “Adapter Cal Failure” message
displays. Remove the source of CO
2
and repeat the
calibration.
