ResMed III & III ST Helpful Hints, Using a Battery and an Inverter, Starting out, Mouth Leaks

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 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 16.

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.

Note: When using the VPAP with a HumidAire 2i, use a pure sine wave inverter not a modified sine wave inverter.
