Using the Mask-Fitting Feature
The VPAP Malibu Mask-Fitting feature can be used to help you fit your mask
properly. The mask-fitting feature delivers air pressure for a three-minute period,
prior to starting treatment, for checking and adjusting your mask fit to minimize
leaks. If a Ramp time (S mode, CPAP mode) or Settling time (VSet mode) is
selected, this allows you to adjust the mask at a pressure closer to the prescribed
pressure. To use the mask-fitting feature:
1 Fit your mask as described in the user instructions.
2
Hold down the Front key for at least three seconds until air pressure delivery
starts.
The following display will appear on the LCD screen indicating that the Mask-
Fitting feature is in operation. The flow generator will ramp to the Mask-Fit
pressure and will remain at this pressure for three minutes. A Mask-Fit star rating
is also displayed. See “Definitions of Mask-Fit Star Rating” on page 25.
Notes:
• The Mask-Fit star rating display disappears after three minutes.
• Mask-Fit is accessible when the LCD shows the VPAP Malibu screen. It is
also accessible from the Ramp screen or Settling screen (these are only
displayed if a maximum ramp or settling time has been set).
• In S and CPAP modes the Mask-Fit pressure is the set treatment pressure or
10 cm H
2
0, whichever is greater.
• In VSet mode, the mask-fit pressure is 10 cm H
2
O.
• Mask Alarm and SmartStop functions are disabled while using Mask Fit.
3
Adjust your mask, mask cushion, and headgear until you have a secure and
comfortable fit.
Once you have a secure and comfortable fit, check your Mask-Fit star rating on
the LCD screen. Definitions of the Mask-Fit star ratings are presented in Table 1.
Note: If there is another person nearby to check your Mask-Fit star rating, you
can adjust your mask, mask cushion, and headgear while lying down.
4
After three minutes, treatment will begin.
• If you do not wish to wait three minutes, hold down the Front key for at
least three seconds and treatment will begin immediately.
• If you press the Front key for less than three seconds, the unit will return
to standby mode (the VPAP Malibu, Ramp or Settling screen is displayed).
