How To Use Your H850 Personal Oxygen System
CAUTION: You must use a dual-lumen cannula of
7-foot length (2.1 m) or shorter (see accessories list at
the end of this manual) to ensure proper oxygen
delivery from the H850 Portable in demand or
continuous mode. Make sure both connections of the
dual-lumen cannula are firmly attached to the H850
Portable oxygen outlet and sensor connectors.
3. With the tips of the cannula and lip rest pointing
downward and toward you, place the two tips into
your nostrils. Run the tubing over your ears and then
slide the sleeve up under your chin until the cannula
feels comfortable (Figure 7). Then breathe normally.
