Nafion Tubing
The Nafion tubing is a single-use, disposable component designed to be placed between the
moisture trap and the nasal cannula or sample line to remove water vapor.
Attaching the Nafion Tubing
1. Connect male end of the Nafion tubing to the moisture trap. Turn clockwise to tighten.
2. Connect female end of the Nafion tubing to the sample line or cannula. Turn clockwise to
tighten.
3. Ensure that the Nafion tubing is firmly attached.
Single-Patient Use, Disposable Moisture Trap and
Filter
The moisture trap and filter are single-patient use, disposable components. During long-term
monitoring of a patient, the moisture trap fills up with liquid (condensed moisture from breathing).
Check the moisture trap frequently and replace when necessary.
Make sure to keep a sufficient supply of new moisture traps and filters within easy reach.
When the moisture trap is removed, guide marks (numbered 1 and 2) and arrows, are visible on
the back of the monitor. These guide marks help the operator insert the moisture trap.
Replacing the Moisture Trap/Filter
CAUTION:
Water or other liquid in the sample line may cause erroneous EtCO
2
readings or an occlusion.
CAUTION:
Ensure that all connections are tight, leak-free, and properly attached.
CAUTION:
If the Nafion tubing becomes contaminated or damaged during use,
discard it and replace it with a new one.
CAUTION:
The sample line, moisture trap, filter, and Nafion tubing are single-patient
use, disposable components. Do not reuse disposable accessories. Accessories
marked “single-use” must be used on one patient only and be disposed of after
usage. Dispose of all components in accordance with your local, state or national
regulations regarding waste management.
CAUTION:
After exposing the monitor to an environment outside of normal room
temperature/humidity conditions, always replace the moisture trap and filter before
each use.
