If using the plastic sizing gauge, insert each size into the nostril. The bottom
rim of the gauge should not go into the nostril. Choose the size that best
seals the nostril. When choosing between sizes, choose a larger size for a
more robust seal with less insertion into the nostrils.
Select a cushion that fills the nostrils comfortably without any gaps between
the cushion and the walls of the nostrils. The bottom rim of the cushion
should not go into the nostril.
1.
Look at the markings on the pillows cushion to determine the correct
placement of the cushion onto the cushion attachment hub. The arrow
on the cushion and the arrow on the interface should be on the same side,
but may not align perfectly.
2.
Attach the pillows cushion to the cushion attachment hub. This should be
done one side at a time. Place the hole located on the side of the cushion
over the corresponding post located on the hub.
3.
Stretch the cushion over the cushion hub
to attach the other side of the cushion.
The cushion will stretch without tearing.
4.
For proper placement of the cushion into
the nostrils, rotate the cushion on the hub
at approximately a 45° angle before
inserting it into the nose.
