Problem / possible cause
Pressure required for treatment may
have changed.
There is a large impedance (eg,
antibacterial filter) in the air circuit.
Humidifier control dial set too high,
resulting in accumulation of water in the
air tubing.
Treatment pressure seems high
Pressure required for treatment may
have changed.
There is a change in the impedance in the
circuit configurations.
The device does not start when you breathe into the mask
SmartStart/Stop not on.
Breath is not deep enough to trigger
SmartStart.
There is excessive leak.
Plug(s) missing from port(s) on mask.
Air tubing is not connected properly.
Air tubing is kinked or punctured.
There is a large impedance (eg,
antibacterial filter) in the air circuit.
The device does not stop when you remove your mask
SmartStart/Stop is disabled.
Use of a full face mask or tracheostomy
tube.
Incompatible accessories (eg, humidifier
or mask system) with high resistance
being used.
High Leak Alarm or Low Min Vent alarms
are set to ON.
"Confirm Stop" is enabled.
High Leak Alarm is enabled, but alarm does not activate when the mask
is removed during treatment
Incompatible air delivery system being
used.
Pressure settings are too low for the air
delivery components being used.
Learn Circuit failed
• The circuit configuration is
inappropriate as the impedance
detected is too high.
• Too many components have been
included or the impedance of
accessories in use is above ResMed's
recommendation, eg, type of filter,
external humidifier, air tubing.
Solution
See your clinician to adjust the pressure.
Perfom the Learn circuit function.
Turn humidifier control down and empty
the water from the air tubing.
Consult your clinician.
Perform the Learn Circuit function.
Consult your clinician.
Take a deep breath in and out through the
mask.
Adjust position of mask and headgear.
Replace plug(s).
Connect firmly at both ends.
Straighten or replace tubing.
Perform the Learn circuit function.
Consult your clinician.
SmartStart is disabled if Full face mask or
Trach is selected as interface.
Use only equipment as recommended
and supplied by ResMed.
Consult your clinician.
Consult your clinician.
Use only equipment as recommended
and supplied by ResMed.
Perform the Learn circuit function to
adjust the therapy pressure according to
your air tubing system.
Review the components included in the
circuit configuration and adjust as
appropriate, then rerun Learn Circuit (see
"Setup menu" on page 16).
