Nasal Cannula
A nasal cannula with tubing are used to deliver oxygen from the Focus unit to the user. The tubing is connected to the unit’s
oxygen outlet (See Figure 18).
AirSep recommends a nasal cannula with 7 ft (2.1 m) of tubing, AirSep Part No. CU002-1, or other suitable cannula. Other
lengths of non-kinking/star channel cannula can be used for a total length of up to 25 ft (7.6 m) maximum.
When Focus is operating but does not sense breathing for 15 minutes, a constant alarm sounds, and the amber alarm light
illuminates simultaneously. If this occurs, check the connection from the cannula to the Focus unit, make sure that the nasal
cannula is positioned properly on your face, and ensure that you are breathing through your nose. (Your physician may
recommend the use of a chin strap if needed.) If the alarm condition continues, change to another source of oxygen as available,
and contact your Equipment Provider.
Ensure the cannula is fully inserted and secure. This ensures that the Oxygen Concentrator can properly detect
inspiration for oxygen delivery. During inhalation, you should hear or feel oxygen flow to the prongs of the nasal
cannula.
Always follow the cannula manufacturer’s instructions for proper use. Replace the disposable cannula as
recommended by the cannula manufacturer or your Equipment Provider. Additional supplies are available from
your Equipment Provider.
Cannula tubing must be non-kinking, which can be used for a total length of up to 25 ft (7.6 m) maximum
