Measurements
WARNING • Danger - explosion hazard - sidestream measurement should not be used in the presence of
flammable anesthetics such as:
– flammable anesthetic mixture with air
– flammable anesthetic mixture with oxygen or nitrous oxide
•CO
2
should not be measured in the presence of aerosolized pharmaceuticals.
• When using the nasal FilterLine, if one or both nostrils are partially or completely blocked, or the
patient is breathing through the mouth, the displayed EtCO
2
values may be significantly low.
• Reflux of gastric contents, mucus, pulmonary edema fluid or endotracheal epinephrine introduced
into the detector can increase airway resistance and affect ventilation. Discard accessory if this
occurs.
• The presence of carbonated beverage or antacids in the stomach may cause incorrect readings and
unreliable capnography in identifying esophageal intubation.
Using the Nasal FilterLine
To set up Et C O
2
measurements using the nasal FilterLine, perform the following steps:
1 Attach the FilterLine tubing to the CO
2
Inlet port as described in “Connecting the CO
2
FilterLine” on page 40.
2 Check that both nostrils are clear and position the nasal FilterLine on the face by inserting the
FilterLine tips into the nostrils.
3 Pass the FilterLine tubing over the ears, then slide the sleeve up the tubing towards the neck to a
comfortable fit under the chin. If using dual purpose FilterLine tubing, connect the green tubing
to the oxygen source. Check the positioning of the FilterLine regularly to ensure proper
monitoring function.
4 Change the nasal FilterLine every 24 hours, if the CO2 Occlusion INOP message appears, or if
measurement readings become erratic.
Using the FilterLine and Airway Adapter
To set up Et C O
2
measurements using the FilterLine and airway adapter:
1 Attach the FilterLine tubing to the CO
2
Inlet port as described in “Connecting the CO
2
FilterLine” on page 40.
2 Connect the wide end of the airway adapter to the endotracheal tube and connect the narrow end
of the airway adapter to the ventilator tubing or manual resuscitator.
Disconnect the FilterLine during suctioning and nebulizing therapies. For best results for non-
humidified use, change the FilterLine after 24 hours of continuous use. For humidified use, change the
FilterLine H after 72 hours of continuous use.
