Note
For monitoring times exceeding 6 hours, Nafion
tubing is recommended.
Selecting a Sidestream Cannula
Select a sidestream cannula based on the patient's size
and monitoring situation. Nasal and nasal/oral cannulae
are disposable and single patient use.
Attaching the LoFlo Module Cable and
Inserting the Sample Cell
Follow these steps:
1. Attach the LoFlo module cable to the CO
2
connector
at the back of the M Series unit.
2. Remove the LoFlo sampling cannula or airway
adapter kit from the package.
3. Insert the LoFlo sample cell into the LoFlo sample
cell receptacle and ensure that it clicks into place.
4. Ensure that the LoFlo module exhaust tube vents
gasses away from the module environment.
5. Turn the selector switch on the M Series to
MONITOR (ON for AED units).
6. Wait for the CO
2
module to warm up.
The unit will display the "WARM UP" message for
approximately one minute while the module and
accessory warm 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
Module
The first time a particular LoFlo module is connected to
the M Series, the unit displays the message “ZERO CO2
MODULE” following the warm up period.
The unit retains the LoFlo module zero settings during
and after its use. When the previously used module is
reconnected to the M Series unit, module zeroing does
not have to be repeated, as long as no other LoFlo
module has been connected and zeroed during the
interim period.
Note
After the initial zero procedure, the LoFlo module
may be used during the warm up period. The
capnogram, EtCO
2
, and respiratory rate will be
displayed; however, full product specifications are
not achieved until the warm up period has
completed.
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
2
(including the patient's -- and your own --
exhaled breath and ventilator exhaust valves).
