Battery Fully Charged

When FreeStyle is connected to an AC or DC outlet and is either in operation or is off, the
green 100% battery gauge/indicators displays to indicate that the battery is fully charged.
2.3.7 Cannula Disconnect (No inspiration detected)
When FreeStyle is operating and does not sense breathing within 15
minutes, a red light will illuminate with a constant audible alarm. If this occurs, the
patient should be instructed to check the connection from the cannula to the FreeStyle
unit, make sure that the nasal cannula is positioned properly on the 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,the patient should change to an alternate
source of oxygen and contact the Equipment Provider.
2.3.8

Performance Warning

If the user's breathing rate causes the Freestyle unit's capacity to be exceeded. The
amount of oxygen that FreeStyle supplies is dependent on the flow control switch setting
and the breathing rate. If the breathing rate is too fast for the flow selector setting, the
capacity of FreeStyle can be exceeded. The patient should reduce activity or consider
locating another source of oxygen.
2.3.9

FreeStyle Capacity Exceeded

When the patient's breathing rate has caused the capacity of FreeStyle to be exceeded, a
1/2-second alarm sounds every 1/2 second, and the red alarm/ service light flashes. When
this occurs, oxygen concentration is outside specifications. The patient should reduce
activity or change to another source of oxygen and contact the Equipment Provider.

2.3.10 General Malfunction

If a general malfunction of the FreeStyle unit occurs, a 1/2 second alarm sounds every 1/2
second, and the red ALARM light turns on. When this occurs, oxygen concentration is
outside specifications. The patient should change to another source of oxygen and contact
the Equipment Provider.
