Disposal of gases
When N
2
O and volatile anesthetics are used, prevent operating
room pollution by connecting the sample gas outlet (gas exhaust) of
the module to the scavenging system. Follow local hospital’s
regulations.
Scavenging through the ventilator reservoir
1. Connect an exhaust line to the sample gas outlet (gas exhaust)
on the module's front panel.
2. Attach the other end of the line to the ventilator reservoir. Make
sure that the reservoir tube diameter is at least 2 to 3 times
larger than the exhaust line.
Scavenging through the anesthesia gas scavenging system
Anesthesia machines are equipped with an anesthesia gas
scavenging system (AGSS), and in some machines you can connect
the sample gas outlet directly to it. See the anesthesia machine's
user documentation to find out where and how the sample gas can
be connected.
Connecting directly to the scavenging system
1. Connect the exhaust line to the monitor's sample gas outlet.
2. Connect the exhaust line only to an open scavenging system
where gas is removed at room pressure.
NOTE: Do not connect the monitor directly to a strong vacuum
scavenging system.
NOTE: If the E-miniC is used, do not return sample gas to the patient
circuit.
Troubleshooting
• Values are too low:
− Check the sampling line and connectors for leakage.
− Check the patient status.
• Values are too high:
− Check the sampling line for blockage.
− Check the patient status.
• Module does not work:
− Check and clean the filter if necessary.
− Check the water trap. If it was too full, liquid may have
entered the module. Replace the module and have it
checked by authorized service personnel.
• No airway gas values:
− Check that the gas sampling line is connected to the water
trap.
