To perform a Capnostat® sensor calibration:
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 sensor calibration cannot be
performed until the “CO
2
: Sensor Warming Up” message disappears.
2. Place the Capnostat® onto the ZERO cell.
3. The “Sensor on Zero Cell” message is displayed.
4. Select Start Zero Cal - Yes from the CO

levels. Measurement can be acquired via a nasal cannula (non-intubated) for oxygen and
CO

only, or through a sampling line connected to a breathing circuit (intubated).
WARNING: The maximum sampling rate at the nasal cannula is 200 ml/
min. This device should not be used on patients whose
breathing could be impaired by this vacuum flow rate.

1. For non-intubated patients, apply the nasal cannula to the patient. For intubated patients
connect the sample line to the breathing circuit. Refer to instruction provided in the
packets.
2. Connect the other end of the nasal cannula or sample line to the Gas Module at the
Input Port (41). Refer to Figure 1-57 on page 93. Do not connect anything to Reference
Port (51), Figure 1-58 on page 95, on the rear of the unit. This port is used to monitor
the room air only. Ensure all tubing connections are tight.
WARNING: Connection of the Gas Module exhaust port (50) to the
hospital’s waste gas scavenge system is strongly
recommended to prevent exposure of hospital personnel to
the patient’s respiratory sample. Vacuum (negative
pressure) should not exceed 1 mmHg at the Gas Module
Pump Exhaust fitting (50). Excessive scavenge vacuum may
result in damage to the Gas Module’s internal pump.
