AirSep FreeStyle 5 Patient Manual page 26

An audible alarm sounds if FreeStyle 5 has a low battery, if the cannula is disconnected, or if performance of the unit is outside
specifications. The light and audible alarm conditions are explained in detail below and summarized on the chart later in this
section of the manual.
In the event of an alarm or you observe FreeStyle 5 is not working properly; consult the Troubleshooting section in this
manual. If you cannot resolve the problem, consult your Equipment Provider.
If you feel discomfort or are experiencing a medical emergency, seek medical assistance immediately.
 Start-Up
A brief alarm sounds at start-up. FreeStyle 5 begins to operate when the alarm stops.
 Low Battery
As the battery power approaches a low level, a brief alarm sounds intermittently, and the yellow 25% Battery gauge /
indicator (Figure 12) light also illuminates intermittently. When this occurs, connect FreeStyle 5 to a DC power outlet or
to an AC power outlet, or change to another source of oxygen within two minutes. When FreeStyle 5 is connected to DC
power outlet or AC power outlet, the unit operates while recharging FreeStyle 5's battery simultaneously. The level of
battery charge is indicated by the battery gauge/indicator(s).
 Cannula disconnected
When FreeStyle 5 is operating but does not sense breathing, a constant alarm sounds, and the yellow alarm light
illuminates after 15 minutes. If this occurs, check the connection from the cannula to the FreeStyle 5 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 continues to sound, change to another source of
oxygen as available, and contact your Equipment Provider.
 FreeStyle's capacity is exceeded
If your breathing rate causes the capacity of FreeStyle 5 to be exceeded, a rapid alarm sounds every ½ second, and the
alarm light illuminates yellow intermittently. When this occurs, the breathing rate of the FreeStyle 5 is outside of the unit
specifications. 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.
 General malfunction
If FreeStyle 5 has a general malfunction, a rapid alarm sounds every ½ second, and the alarm light illuminates red
continuously. When this occurs, the concentration of oxygen that FreeStyle 5 is supplying is below unit specifications.
You should change to another source of oxygen as available, and contact your Equipment Provider.
