Airway gases
1. Select a gas related parameter window.
2. Select the Agent/N2O tab > Setup .
3. Select an option from the Agent Sweep Speed list. The options are: 0.625 mm/s ,
6.25 mm/s , 12.5 mm/s , 25 mm/s , and 50 mm/s .
The smaller the value, the slower the sweep speed.
Setting agent limit alarms
1. Select a gas related parameter window.
2. Select the Agent/N2O tab > Alarms .
3. Check that the required alarm ( EtAA or FiAA ) is on, and set its high and/or low
limit values.
Gases alarm priorities
You can select priorities for the CO2 high/low , FiAA high/low , RR (CO2) high/low , and
Apnea (CO2) alarms through Alarm Setup > Alarm Priorities > Other Parameters . The

Preventing operating room pollution
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.
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 module'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 module directly to a strong vacuum
scavenging system.
NOTE
If the E-miniC is used, do not return sample gas to the patient
circuit.
