Solution
Check that the nasal pillows with the left (L)
and right (R) indicators are inserted correctly (L
into your left nostril, R into your right nostril).
Carefully follow the fitting instructions.
Readjust the headgear to ensure it is fitted
comfortably.
Squeeze pillow sides to release inner wall. The
correct position is shown in the reassembly
instructions.
Talk to your clinician.
Clean pillows according to the instructions.
Adjust the headgear split bands.
If your headgear does not come with a buckle,
wash the headgear to help it return to its
original form. Follow the washing instructions.
If your headgear comes with a buckle, adjust
the headgear by pulling the headgear through
the buckle. Adjust only enough for a
comfortable seal and do not overtighten. You
may need to adjust the headgear as it
stretches over time.
If the vent requires cleaning, use a soft bristle
brush. The vent may discolor over time and this
is not a safety concern. Follow the cleaning
instructions in this guide to maintain
performance and safety of the mask.
Ensure the vent is dry after cleaning and in the
case of excess condensation.
Disassemble the mask, then reassemble
according to the instructions.
Refit or reposition your mask. Adjust your
headgear. Check your mask is assembled
correctly.
