Passport V Operating Instructions 0070- 0-0704-02 11 - 7
Gas Monitoring (optional) Gas Menu
NOTE: The Gas Module 3 uses a fixed correction of 11 hPa to
compensate for the influence of water vapor in the gas
sample, when converting the gas readings to ATPD. An
increase in the ambient H
2
O partial pressure to 30 hPa
(i.e. 28 °C, 80% RH or 33 °C, and 60% RH) will cause a
general error for all gases of only -2% REL.

NOTE: To prevent moisture from entering the pneumatic system,
ensure that the Gas Module is always installed and
operated in the horizontal orientation shown in all graphical
depictions.
1. Power ON the Gas Module.
2. Power ON the patient monitor while holding down the Discharge key to enter into its
Installation Mode.
3. From the patient monitor Installation Menu, set the correct serial port to “Gas
Module” and then select “Save Current”.
4. Restart the patient monitor to enter normal monitoring mode.
5. Set alarms as desired.
NOTE: DRYLINE
™
Sample Lines are for use with Gas Module 3 only.
6. 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
sample line packets.
7. Connect the other end of the nasal cannula or sample line to the Gas Module at the
input port.
WARNING: Connection of the Gas Module exhaust port to the hospital’s
waste gas scavenging 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.
Excessive scavenge vacuum may result in damage to the
Gas Module’s internal pump.
CAUTION: Contamination with CO2, N2O or Anesthetic Agent in the air
surrounding the Gas Module may cause significant
measurement errors. The Gas Module exhaust output
should be connected to a medical gas-scavenging system.
8. Check for a clean water trap.
