2.3.6 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.
