Adjusting for leaks
In the event of leaks, follow these recommended methods to obtain a better seal:
1. Re-seat the mask. Pull the mask directly away from the face and gently set it
back into place. This allows the cushion to create a new seal on the face.
2. Adjust the forehead support arm StabilitySelector to correct leaks.
This is an important step in the fitting process.
Problem: Leaks around the bridge of the nose or into the eyes.
Solution: Adjust the forehead support arm to a lower position by gently
squeezing the arms of the StabilitySelector and sliding it
downward to a lower position. This will bring the top of the
cushion closer to the face. If necessary, re-seat the mask again.
Problem: Leaks below the nose or near the lip.
Solution: Adjust the forehead support arm to a higher position by gently
squeezing the arms of the StabilitySelector and sliding it upward
to a higher position. This will bring the bottom of the cushion
closer to the face. If necessary, re-seat the mask again.
3. Tighten the headgear. If leaks are still
present, apply pressure with the fingers
directly to the mask in the location of
the leak. If this eliminates the leak,
tighten the headgear straps closest to
the leak to accommodate the seal.
Do not over-tighten the headgear.
Note: Excessive tightening of the
headgear may cause unnecessary
discomfort and leaks. Remember,
not all leaks need to be corrected.
