5. Check that the connections have been made correctly by verifying a proper CO
2
waveform (capnogram) on the monitor display.
NOTE: The CO
2
waveform is displayed by choosing Auto Display
CO
2
as Waveform 2 or 3 and the Resp Source as CO
2
/Off or
CO
2
/ECG in the Setup menu.
6. The sensor cable should face away from the patient. To secure the sensor cable safely
out of the way, attach the sensor cable holding clips to the airway tubing, then connect
the sensor cable to the clips.

Sensor Calibration Verification
Calibration can be verified at anytime and should be verified at least once a week.
To verify calibration:
1. Verify the Passport is turned on and the Capnostat® is connected and warmed-up.
2. Place the Capnostat® sensor onto the reference cell labeled REF.

The “Sensor on Reference Cell” message is displayed and the reference value is
displayed in the ETCO
2
window. The value should be between 36 and 40 Torr.

Sensor Calibration
The Capnostat® CO
2
sensor does NOT need to be calibrated at each monitor power up.
Calibration of a sensor is required the first time a particular sensor is connected to a
particular monitor and when the monitor requests it.
Once a sensor is calibrated, the Passport XG can be turned off and on, the sensor can be
unplugged and reconnected, without having to recalibrate. However, if a second sensor is
connected in place of the original, the second sensor must be calibrated and if the original
sensor is used again, it too will have to be recalibrated.
NOTE: In order to perform an accurate Sensor calibration, the
“Sensor Warming Up” message must not be displayed.
To perform a Capnostat® sensor calibration:
1.
Verify the Passport XG is turned on and the Capnostat® is plugged in and warmed-up.
