Helpful Hints
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 clinician
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 12.
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 III ST-A
International Use
Your VPAP III ST-A 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 will require an approved
power cord for that country.
Using a Battery to Power the VPAP III ST-A
The VPAP III ST-A can be powered by battery using the ResMed DC-24/30
Converter, an inverter or a UPS (uninterruptible power supply).
Battery Requirements
We recommend a 12V or 24V deep-cycle battery. Battery capacity is determined
by VPAP III ST-A's power consumption which is mainly affected by the IPAP
pressure, usage hours and whether or not an integrated humidifier is connected.
