3.1.3 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 (Figure 10).
AirSep recommends a nasal cannula with 7 ft (2.1 m) of tubing, AirSep Part No. CU002-1 or 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.
Always follow the cannula manufacturer’s instructions for proper use. Consult your licensed health care
provider to determine how often the cannula should be replaced.
Cannula tubing must be non-kinking, which can be used for a total length of up to 25ft (7.6cm) maximum.
Ensure the cannula is fully inserted and secure. This ensures that the Focus unit can properly detect
inspiration for oxygen delivery.
