Selecting a Sidestream Cannula
Select a sidestream cannula based on the patient's size
and monitoring situation. Nasal and nasal/oral cannulas
are disposable and single patient use.

Inserting the Sample Cell
Follow these steps:
1. Remove the LoFlo sampling cannula or airway
adapter kit from the package.
2. Insert the LoFlo sample cell into the LoFlo sample
cell receptacle and ensure that it clicks into place.

3. Ensure that the LoFlo module exhaust tube vents
gases away from the module environment.
4. Turn the selector switch on the E Series to
MONITOR (ON for AED units).
5. Wait for the CO module to warm up.

The unit will display the WARM UP message for
approximately one minute while the module warms
up to operating temperature. The message
disappears when the module is ready for use.
Note Warm up time varies with ambient temperature of
the module.
Zeroing the LoFlo CO
2
The module/sample cell zero allows the LoFlo CO
module to adjust to the optical characteristics of the
sample cell. While zeroing is recommended the first time
a particular LoFlo module is connected to the unit, it is
only absolutely necessary when the message ZERO
CO2 MODULE is displayed.
CAUTION! Always ensure that the sample cell is
properly connected to the LoFlo module
before zeroing.
1. Ensure that the nasal cannula or on-airway adapter is
not connected to the patient or close to any source of
CO (including the patient's -- and your own --
2
exhaled breath and ventilator exhaust valves).
2. Press the Param. softkey and select the EtCO
item, then press Enter.
3. Press the Zero softkey.
The unit zeroes the module and displays the
ZEROING CO2 MODULE message for
approximately 15-20 seconds.
The units displays the message ZERO DONE upon
completion of the zeroing.
Note Do not attempt zeroing for 20 seconds after
removing the adapter or cannula from the patient's
airway. This time allows any CO
adapter or cannula to dissipate before zeroing. Do
not attempt to zero the module while the adapter or
cannula is in the patient's airway. Zeroing with CO
in the adapter or cannula can lead to inaccurate
measurements and/or other error conditions. If you
attempt zeroing while CO
or cannula, the time required to zero the module
may be increased. If zeroing cannot be completed,
the message "ZERO FAILED" will be displayed. If
this occurs, clear any occlusion in the adapter or
cannula, remove the source of CO
seconds, and try zeroing again.
Applying a Sidestream Airway Adapter Kit
The sidestream airway adapter kit is intended for
monitoring the EtCO of intubated patients.
2
Before attaching the airway adapter to the breathing
circuit, verify that the adapter is clean, dry, and
undamaged. Replace if necessary.
