Cannula disconnected
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.
Focus’s capacity is exceeded
If your breathing rate causes the capacity of Focus to be exceeded, an alarm sounds 3 times every ½ second with a 5
second pause, and the amber alarm light illuminates simultaneously. You should reduce any physical activity, reset alarm
by turning unit off and back on, and then if necessary change to another source of oxygen as available, and contact your
Equipment Provider.

1) An audible alarm sounds (beep,beep) and the red alarm light illuminates.
If this alarm condition occurs, change to another source of oxygen as available, and contact your Equipment
