Fisher & Paykel Oracle 452 NIV Oral Mask with Headgear

See Details
If you are purchasing a new CPAP, Auto CPAP or BiLevel (BiPAP) machine, humidifier or an oxygen concentrator, then federal law requires that we receive a copy of a prescription written by your doctor. A sleep study report does not qualify as a prescription.  Also, the purchase of complete CPAP masks does require a prescription.  (*** Note that the component parts that make up the mask DO NOT require a prescription! ***)
The prescription must state that it is for CPAP therapy and at what pressure your machine should be set. If you are purchasing a standard CPAP machine (one that operates at a constant pressure), then the prescription must show one pressure setting, which is generally a number between 4 and 20 and measured in cm of H2O. If you are purchasing an Auto CPAP machine, then your prescription must state two different pressures: A low (minimum) pressure setting and a high (maximum) pressure setting. If you are purchasing a BiLevel machine, then your prescription must state two pressure settings: An inspiratory (IPAP) setting and an expiratory (EPAP) setting.  If you are purchasing an Oxygen Concentrator, the prescription should have the flow rate stated in Liters per minute. 
Prescriptions can be faxed to us at 888-469-2555, or we can accept a scanned copy of your prescription by emailing it to us at [email protected].

Please note that orders for machines, concentrators, or complete masks will NOT be shipped until we receive a copy of your prescription!

The Oracle 452 from Fisher & Paykel offers a unique solution for mouth breathers and patients with chronic nasal obstruction. The Oracle is an oral mask which delivers pressure exclusively through the mouth rather than the nose. It is small, unobtrusive and easy to wear.
The Oracle 452 comes pre-assembled with headgear, and includes many options and customization features to help you get best fit right out of the box. The Rotating Adjustment Dial offers continuous adjustment of the distance between the SnapFlap Cover and the SoftSeal Mouthpiece for a personalized fit. Two sizes of Silicone SoftSeals are provided so that you can select whichever you prefer -- small or large.
** Note - The Oracle HC452 is an oral mask - NOT an oral appliance. It is designed to float in the mouth and is retained in position by two silicone components that form a pressure seal against the inner and outer cheek. No dental fitting is required. The Oracle 452 should only be used on CPAP/BiLevel Systems that include Heated Humidification.
Product Features
  • Floats comfortably in the mouth; Easy fit of the mouthpiece prevents skin abrasions from pressure points

  • Single Strap Headgear - Minimal, cool lightweight and comfortable single Breath-O-Prene strap allows clear vision and movement
  • Flexitube tubing position can be rotated 360§ for perfect positioning
  • Chin straps are eliminated, resulting in a less cumbersome setup. Also, the concern of mouth leak is eliminated
  • Glasses and dentures can easily be worn with this product

The only mask I can use
I've tried other masks, and this one is the only one that I can wear for more than 4 hours. Is it perfect? No. Does it work? Yes. Pros: - Oral air flow,, NOT NASAL, so it actually works for me. - Effective for me (I am a mouth breather, and no air goes out my nose, so no need for nose plugs/clamp) - Fits well. Adjusts easily both around your head, and mouth seal. - Doesn't leak much (well within acceptable limits according to my doctor). - Can wear 6-7 hours without pain. - Not too big. - Travels well. - Durable (I just got my 3rd one, and each has lasted me about 2.5 years) - Easy to clean. - Easy to change filter. - Light and small. Cons: - Dry mouth in morning (even with humidifier set to max) - Plastic clips that hold headgear on mask sometimes fall off when handling the mask (never while in use) - minor annoyance.

This mask did not work out for me. I experience alot of moving and air leakage. I had such high hopes because I am a mouth breather. You don't know until you try and find a mask that addresses your particular situation.

Oracle gives your freedom
I have a total of 5 masks and have made many attempts at trying to use them. However, I always come back to the Oracle for a 'successful' nights sleep. Other masks tend to have serious leaks if you need a reasonably high pressure whereas the Oracle has nil or minimal leaks. Plus, again unlike other masks, you don't have to strap it on to your head so tight that you feel like a ‘crash test dummy’ and the strap pressures wake you through the night (if the leakage hasn't already). Good luck!

Love this mask. I had multiple problems with other masks especially pressure point abrasions and they felt claustrophobic. This is small, simple to use and no leaks. I highley recommend this mask if your a mouth breather and have to use a high pressure on your cpap.

I don't usually write a review, but felt I had to this time to help someone know my experience before they make the same mistake. I have had such a terrible experience with this mask. It fills up my mouth so full that it is uncomfortable but the worst part is that my mouth is so terribly dry by using this, even with a humidifier, that it keeps me awake a lot of the night. I spent a lot of money out of my pocket & it is no good at all to me.
