Starting out
Mouth Leaks
If using a nasal mask, try to keep your mouth closed during treatment. Air
leaks from your mouth can decrease the effectiveness of your treatment. If
mouth leaks are a problem, a full face mask or chin strap may help. Contact
your clinician or equipment supplier for further details.
Mask Fitting
The flow generator delivers the most effective treatment when the mask is
well fitted and comfortable. Treatment can be affected by leaks, so it is
important to eliminate any leaks that may arise.
If you have problems trying to get a comfortable mask fit, contact your sleep
clinic or equipment supplier. You may benefit from a different size or style of
mask.
You can also use the Mask-Fitting feature to help you fit your mask properly.
See “Using the Mask-Fitting Feature” on page 14.
Before wearing your mask, wash your face to remove excess facial oils. This
will allow a better fit and prolong the life of the mask cushion.
Nasal Irritation
Dryness
You may experience dryness of the nose, mouth and/or throat during the
course of treatment, especially during winter. In many cases, a humidifier
may resolve this discomfort. Contact your clinician for advice.
Runny or Blocked Nose
You may experience sneezing and/or a runny or blocked nose during the first
few weeks of treatment. In many cases, nasal irritation can be resolved with
a humidifier. Consult your clinican for advice.
Travelling with the VPAP
International Use
Your VPAP flow generator has an internal power adapter that enables it to
operate in other countries. It will operate on power supplies of 100–240V
and 50–60Hz. No special adjustment is necessary, but you may need a plug
adapter for the power outlet.
Using a Battery and an Inverter
Your VPAP can be powered by a battery using an inverter. We recommend
a 12V or 24V deep-cycle battery, and any CE or UL marked inverter with a
minimum continuous output power rating of 200W.
