Fisher Paykel Oracle:
This is considered a niche mask since it likely won’t work for the majority of the population.
It is called an OPAP (oral positive airway pressure) This is great for people who have a very difficult to fit face shape. It is also very good for people who are experiencing breakdown on the bridge of the nose. This doesn’t have to be an everynight mask. It can be used just for a change, or to allow time for your nose to heal or “decompress” from a standard Full Face Mask.
My recommendation is to turn the heated humidification up all the way. This can really dry out your mouth if you don’t. You will also notice that for the first 2-3 nights you can have some drooling problems.
The Oracle is very easy to put on and fit. The headgear is almost not even necessary, but very minimalistic.
Don’t hesitate to contact me on my forum if you have any questions. (link at the bottom of this page)
