Gases (Optional) Gas Monitoring with Gas Module 3
2.4 Gas Monitoring with Gas Module 3
WARNING: When using the Gas Module 3, the maximum sampling rate at the nasal
cannula is 200 ml/min with an Adult/Pediatric water trap and 120 ml/
min with a Neonatal water trap. This device should not be used on
patients whose breathing could be impaired by this vacuum flow rate.
NOTE: The Gas Module 3 is equipped with au
to
matic barometric pressure
compensation.
NOTE: The Gas Module 3 uses a fixed correction of 11 hPa to compensate for
the i
n
fluence of water vapor in the gas sample, when converting the
gas readings to ATPD. An increase in the ambient H20 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 G
a
s Module 3 is always installed and operated in the horizontal
orientation shown in all graphical depictions.
1. Ensure that the VDI module connected with the Gas Module 3 is connected to the V 12/V 21.
2. Turn on the Gas Module 3 and the V 12/V 21.
3. Select Gas as the VDI mode in the Integrated V Hub or V Hub x (x represents the V Hub
number) from the menu in the Module Status dialog. Refer to "Changing VDI Modes" on page
5-4 in the V Series Operating Instructions for additional information.
4. Configure Gases and CO

to display on the Main Screen. Refer to "Display Options Dialog" on
page 3-2 in the V Series Operating Instructions for additional information.
5. Set alarms as desired. Refer to "Configuring Gases Alarm Limits" on page 2-3 for additional
information.
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 instructions provided in the sample line packets.
7. Connect the other end of the nasal cannula or sample line to the Gas Module 3 at the input port.
Ensure all tubing connections are tight.
WARNING: Connection of the Gas Module 3 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 CO

O or Anesthetic Agent in the air
surrounding the Gas Module 3 may cause significant measurement
errors.
8. Check for a clean water trap.
NOTE: The Gas Module 3 must be warmed up a minimum of 45 seconds for ISO
accurate CO
