Nasal Cannula - AirSep FreeStyle Patient Manual

If the power supply remains connected when the internal battery is fully charged, the four LEDs will turn
off after approximately one hour.

Nasal Cannula

A nasal cannula and tubing are used to deliver oxygen from the FreeStyle unit to the user. The tubing is connected to the
unit's oxygen outlet. (See Figure 7.)
AirSep recommends a nasal cannula with 7 ft (2.1 m) of tubing, AirSep Part No. CU002-1. Other lengths of tubing up
to 25 ft (7.62 m) maximum, including nasal cannula, may be used.
Normally, when the unit is in its carrying case, it will be necessary to first feed the cannula through the specially designed
hole in the top center of the case and then to lift the cover of the case to secure the cannula to the oxygen outlet.
