Using the Mask-Fitting Feature

1

2

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:

Fit your mask as described in the user instructions.

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 H20, whichever is greater.

•In VSet mode, the mask-fit pressure is 10 cm H2O.

•Mask Alarm and SmartStop functions are disabled while using Mask Fit.

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.

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).
