Product Details

Oracle 452 Oral CPAP Mask by Fisher & Paykel

Introducing the Oracle 452, Fisher & Paykel's unique oral CPAP face mask. The Oracle 452 Oral Mask delivers pressure through your mouth instead of your nose, providing ideal therapy for mouth-breathers and users who are sick, or those who suffer from nasal obstruction and cannot use or do not like nasal masks, nasal pillows, or full-face masks. The comfortable Oracle CPAP mask does not obstruct your eyes, allowing you a clear field of vision when you use this product.

Comfortable Oral Face Mask is Easy to Use
Setting up your Oracle 452 Oral CPAP Mask is a breeze. Simply place the mouthpiece, which comes in two different sizes (small and large) for your convenience, behind your lips and in front of your teeth. Then, fit the outside flap into the mouthpiece, and then fold it over your lips. This should keep the device in place without touching or blocking your tongue. Removing the Oracle is easy as well: Just pull the Easy-Release Cord to take your mask off.

Quiet Air Diffusion
This may be an oral face mask, but that doesn't make it any louder. In fact, Fisher and Paykel designed the Oracle 452 to be a quiet CPAP mask. The Oracle 452 Oral CPAP Mask comes with a filter to stifle noise, and exhalation holes near the elbow of the device to help diffuse air away from you and your partner.

Single Strap Headgear
Tired of obtrusive, uncomfortable, and invasive headgear? The Oracle's single-strap headgear is small and lightweight, wrapping around your neck at chin height. With just one strap, the rest of your face is unobstructed, and you'll have zero vision impairment with this CPAP mask. This works great if you do not like too much headgear and hardware on your face.

Rotating Adjustment Dial
If you've ever felt frustrated by your inability to properly adjust your CPAP mask, fear not. Fisher and Paykel have developed an innovative and much-welcomed solution for those who just can't quite get their mask to fit: a rotating adjustment dial. The dial can be literally rotated, letting you tighten or loosen the fit between the headgear strap and the mouthpiece. Simply slide your fingers up and down the dial to adjust the fit - just be sure to maintain proper pressure on the dial as you move it!

Note: The Oracle CPAP mask comes with nose plugs which help users acclimate to mouth breathing during sleep.


Do I have to use the nasal plugs?
No, but we recommend that you use them while you adjust to the mask. If you breathe primarily through your mouth, or if you suffer from chronic nasal congestion, the nose plugs will probably not be necessary.

Do I need a heated humidifier with the Oracle mask?
Yes, you'll really want to use heated humidification with the Oracle 452 Oral CPAP Mask. More so than with most masks, you'll wake up with an excessively dry mouth if you don't use a humidifier.

Can I use any CPAP machine with the Oracle mask?
Yes, the Oracle 452 Oral CPAP Mask is compatible with all CPAP and BiPAP machines except the ResMed AirMini.

Cela va faire une année que j'utilise ce masque oral de Fisher and Paykel, en combinaison avec l'auto-CPAP Icon de Fisher and Paykel.
Je suis ravie de ce masque oral, même si je l'utilise à ma façon!

Voici les points +++
- Facilité d'emploi: masque peu encombrant, non invasif
- Pas de sentiment de "masque", ni d'étouffement
- Pas d'envahissement de toute la figure
- Sangle autour de la tête non nécessaire durant l'utilisation nocturne.
- Pas de difficultés à dormir sur les côtés, ou sur le dos

Voici le seul point négatif
- Les embouts nasaux fournis ne sont pas efficaces: ils laissent passer l'air!

Solution trouvée+++
- En lieu et place des embouts nasaux, j'utilise des "bouchons pour oreilles", en mousse ( marque 3M)
- En plus, pour que l'air ne passe pas du tout, j'y ajoute un morceau de pansement transparent, découpé à la bonne taille, de la marque Comfeel ( 3536)
- J'utilise aussi le tube thermochauffant prévu par Fisher and Paykel .
- Pour parfaire le tout, avant d'aller dormir, j'emploie un gel buccal hydratant.

Conclusions +++
- Avec ces adaptations, tout va bien!
- Plus d'apnées, plus de réveils nocturnes
- Pas d'ennuis de bouche sèche
- Et pour ne rien gâcher, un nez parfaitement dégagé en journée... ( Ce que je n'avais jamais avant!)

Ce masque vaut qu'on s'y intéresse et qu'on l'adapte à sa façon! je lui mets 4 étoiles ( à cause des embouts nasaux non efficaces)

The mask itself was very good. it fit well and I had no issues keeping the mask in my mouth. Using the nose clip to prevent breathing through the nose was a bit painful, but you only have to keep using it until you get used to breathing exclusively through your mouth.

Unfortunately, this ultimately did not work well for me as I needed to use an oral appliance to align my jaw in addition to a CPAP. This did not allow for it. However, just because it did not work well for me does not mean it won't work for you.

If you are predominately a mouth-breather or suffer from severe nasal congestion due to allergies that prevent you from using a nasal mask on a regular basis, then this might be a good option for you.

Subject: Oracle 452 Oral Mask
I like the idea of this mask, but the way that the inner seal connects to the mask becomes uncomfortable very quickly. The hard plastic inner frame piece stays in between my front teeth, and eventually I will lose a tooth or bite through it. Wearing the mask improperly alleviates this, but I can't recommend intentionally wearing the mask improperly.

Hello Ron,

I am sorry to hear the mask is not working for you! I see you have not used our 30 Day Mask Assurance Program. Feel free to give us a call to utilize the program and discuss a mask that may work for you!

As everybody in the word sleep different, I am greatly appreciative of theFisher Paykel Oracle 452 CPAP, as I am a know as a mouth breather. This product is so perfect me and any one who may breathe threw there mouth as they sleep. Most of all this is a safe product that will give you great comfort as you sleep giving you no worries as you complete your therapy. Can't be beat.

Purchased this mask for my boyfriend who has sleep apnea, prior to this he was using your full face mask and he don't like it very much. He liked this better because, he breath thru his mouth when he sleeps and when he started using Oracle 452 he has not complained at ll he is actually loving it, and been having a restful night.

I have used this mask for 8 years due to the fact that
I have nasal problems and cannot wear a nasal mask.
The Oracle 452 suits my needs, never any problems with
leakage, it is light weight and is also great for side sleepers.

The ad does not tell you that you must block your nose (at least at first) to use this. It came with 2 sizes of nostril plugs (neither of which worked). I bought a nose clip (for swimming) and it is most uncomfortable.

I really like this mask, but I really got dry mouth with it, I am waiting on the arrival of a new machine,and I hope that will help. Other than that, I slept great, I love the fact you don't need the headgear with it.

If you like a mask that is oral based then this is for you. It does a fine job if you don't want to cover your face. Suddenly I feel normal wearing this at night.

Do u bill Humana

Sorry no, you would need to contact your insurance regarding coverage or reimbursement first before placing an order with us as we cannot bill insurance directly.

Be sure to confirm with your insurance company these questions:
1. Do you accept a paper claim?
2. What documentation will I need to send with my claim?
3. Will I need to add any modifiers to my claim?
4. May I purchase the CPAP machine and still have it covered?
5. Is Respshop in-network or will I be paying out of pocket for this claim?

On a res med machine what type of mask do you select if you are using the oracle ? The choices are full face,pillows or nasal

This is under Full Face Mask.

If you choose to use the oral Cpap device, do you lose the advantage if nitrous oxide gained by nasal breathing? Are there known health disadvantages?

The mask does come with nasal plugs, however, they may not work for everyone and may cause some discomfort. I am unaware of any health disadvantages. If you would like a mask that covers the mouth but also has the ability to direct air into the nose, we have those options as well.

I am a grinder and I use a top night guard, would I be able to use the oral mask? Thank you🙂

You may have some difficulty using this mask or it may work fine... it really depends on individual factors and you would need to try it to find out. We do have a mask exchange policy so you can always exchange it for another one.
