Fisher & Paykel Healthcare is the first company to develop an oral mask. The Oracle HC452 delivers air pressure only through a mouthpiece. The mask has been clinically proven to treat OSA and offers a viable alternative to a full face mask, with less structure against the face.
Here is how it works:
The mouthpiece comes in two sizes and is placed behind the lips and in front of the teeth. An outside flap is then fitted into the mouthpiece and folded over the lips. This combination keeps the device stable in the mouth and has been redesigned without the inner flap of the earlier design, which rested on the tongue.
The features of the Oracle mask include:
Out of Box Solution. All Fisher & Paykel masks come fully assembled and ready to wear so there is no fumbling or confusion.
Bias Diffuser. The Oracle mask has an exhalation vent design of a series of small holes and uses a filter to help reduce noise. The mask comes with five filters.
Rotating Adjustment Dial. This dial adjusts the space between the SnapFlap Cover and SoftSeal mouthpiece to increase comfort and stability and can be used after the mask has been fitted into the mouth. This is an upgrade to the earlier design of the Oracle.
Single Strap Easy-Release Headgear. One strap around the back of the head keeps the Oracle stable and a swivel in the front of the mask allows free rotation of the CPAP hose. The headgear is adjusted once, then easily removed with just a pull of the Easy-Release cord. No ongoing adjustments are needed.
You can use our online sizing tool to find out which masks will work best with your facial structure.
If you still aren’t convinced that this is the mask for you, all you need to do is buy our Return Insurance and you can send it back within 30 days for a refund of the full purchase price. Read all about it here:
Heated humidification is required with use of the Oracle 452 Oral Mask due to the CPAP air bypassing the nasal airways which normally moisten the air. With higher CPAP pressures, even a heated humidifier may not provide adequate moisture, especially for patients who also take medications that dry the mouth.
We would first recommend a full face mask due to this humidification issue. Air leaking through the nose can be an issue as well and nasal plugs of various sizes are included with the mask. We have many remarks that the nasal plugs can leak, although this is usually negligible.
If the CPAP pressure is low enough, the Oracle is a good alternative to a full face mask, especially for people with nasal blockage, either from chronic congestion, deviated septum or other type of tissue blockage.
A prescription is required to buy this product. You may fax it to us at 1.866.353.2727 or 1.713.541.7370. If you are purchasing a CPAP, BiPAP or APAP machine, please make sure the pressure setting is indicated.
HC452 - Great if you can seal your nose

"I ordered two new masks, this one arrived first.
Used this mask/mouth-piece for a week.
The arrangement of air holes and diffuser is effective. It is very quiet, best of 6 masks I've tried.
It is small, no head/pillow orientation limitations.
Because it is held in place by your mouth, the head strap is optional and if used, doesn't need to be tight. No headaches from this one.
What didn't work for me is having to close off the nose to prevent air leaks. Had me waking to a very dry mouth(using a humidifier). I only tried the supplied nose plugs, there may be a better way. As a result, after ~4 hours I would switch back to a Mirage Quattro Full Face. At least until my FitLife Total Face arrived, now it is all I use.
I only gave it one week and I know the instructions for the HC452 say it can take two weeks for it to become more natural. I just didn't have trouble staying asleep with any other mask from my first day using CPAP."
I tried but it just wasn't for me.

"I was praying that this was the end to the leaking full face masks. It wasn't to be. I loved the idea. But it just was too uncomfortable to me for a few reasons. First, the interface put too much pressure on my two top front teeth. It just felt wierd. Second, the nose plugs were way too uncomfortable and kept falling out. I tried taping them on but that just lead to more discomfort. Finally, the build up of saliva was an issue as well. I had read the feedback about the saliva but figured the people were just complainers (sorry people). It really was strange. If they improve on the design I may be tempted to try it again. But for now I went back to my trusted HC432 full face mask."
Dry mouth and sore throat

"This mask was a good theory, but tended to give me a bad dry mouth and sore throat. I dont use a humidifier, but I dont know how much difference it makes.
Also, I clench my teeth at night, so I kept squeezing the cover off of the hard plastic mouthpiece and waking upo every half hour to drink water or put the soft cover back on.
The service was excellent, but the mask did not work for me, I will have to stick to nasal mask."
