Solution
Refit the mask according to the instructions.
Ensure that the cushion is positioned correctly
on the patient's face before pulling headgear
over their head. Do not slide the mask down
the patient's face during fitting as this may
lead to creasing of the cushion.
Check the patient's face size against the mask
fitting template. Note that sizing across
different masks is not always the same.
