dehydration
cerebrospinal fluid leak, recent cranial surgery, or trauma.
Adverse effects
Patients should report unusual chest pain, severe headache, or increased breathlessness to their
prescribing physician. An acute upper respiratory tract infection may require temporary
discontinuation of treatment.

Troubleshooting
If there is a problem, try the following suggestions. If the problem cannot be solved, contact your
equipment supplier or ResMed. Do not attempt to open the device enclosure.
Problem/Possible cause Solution
No display
Power is not connected. Ensure the power cord is connected and the power outlet (if
available) is on.
The DC plug is partially inserted
into the back of the device or
inserted too slowly.
Fully insert the DC plug.
Insufficient air delivered from the device
Ramp time is in use. Wait for air pressure to build up or change ramp time.
Air filter is dirty. Replace air filter.
Air tubing is not connected
properly.
Check air tubing.
Air tubing is blocked, pinched or
punctured.
Unblock or free the air tubing. Check the air tubing for punctures.
Mask and headgear are not
positioned correctly.
Adjust position of mask and headgear.
Incorrect air tubing selected. If you are using the SlimLine, Standard or 3 m air tubing ensure
that you have the correct air tubing selected via the menu.
Device does not start when you breathe into the mask
Breath is not deep enough to
trigger SmartStart/Stop.
Take a deep breath in and out through the mask.

mask
Incompatible mask system
being used.
Only use equipment recommended by ResMed.
The patient is using a nasal
pillows mask with a set
pressure less than 7 cm H2O.
Disable SmartStart/Stop.
Pressure rises inappropriately
Talking, coughing or breathing in
an unusual manner.
Avoid talking with a nasal mask on, and breathe as normally as
possible.

Check with your clinician/service provider before using the SlimLine air tubing with devices other
than the S9 or H5i.
The electrical connector end of the heated air tubing is only compatible with the H5i air outlet
and should not be fitted to the device or mask.
When using the SlimLine or ClimateLine above 20 cm H2O, the device optimum performance
may not be reached if used with an antibacterial filter. The device performance must be checked
prior to prescribing the SlimLine for use with an antibacterial filter.
The ClimateLine or ClimateLineMAX is designed only for use with the H5i.
