When the desired value is displayed in the Message Bar, press the knob and

unchanged.

The flow rate displayed on the LCD screen indicates the flow rate
exiting the patient outlet port. The "Target" flow is pre-set based on the
CPAP setting. The flow is automatically adjusted to maintain the CPAP
setting and it may normally vary from the Target flow.
5.
The Driver will automatically increase flow up to 3 lpm above the Target
flow to compensate for normal leaks (i.e. leaks around prongs, masks,
or through the patient's mouth).
• If a large leak exists at the patient, and cannot be corrected by
adjusting the patient interfaces, then the Target flow may be set
higher (up to 13 lpm) to provide more flow to compensate for
leaks. If the leak is resolved, the Driver will automatically reduce
the flow to maintain the set CPAP level.
• The flow rate should not be less than 3 lpm. A "low flow" alarm
will activate if the measured flow rate is less than 3 lpm and
would indicate a possible occlusion of the expiratory limb or a
defective circuit / generator. If this alarm occurs, check for
pinched or kinked tubing, or replace the circuit and / or generator.
