Using the HumidAire 2i Warm-up Feature

If using a HumidAire 2i with the VPAP III ST-A, you can use the Warm-up feature to pre-heat the water in the humidifier prior to starting treatment.

After stopping treatment, the VPAP III ST-A will continue to blow air gently to assist cooling of the heater plate.

See the HumidAire 2i User’s Manual for further details.

Using the Mask-Fitting Feature

The VPAP III ST-A 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 is selected, the mask can be adjusted 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 Start/Stop 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 15.
