Nafion Tubing

The Nafion tubing is a single-use disposable component designed to be placed between the

readings.
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.

to tighten.
3. Ensure that the Nafion tubing is firmly attached.
Single-Patient Use, Disposable Moisture Trap and
Filters
The moisture trap and filters are single-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.
