Sleep Apnea Treatment Made Simple.
Treating sleep apnea doesn’t have to mean sleeping with bulky CPAP masks, hoses, cords, or tubes every night. Our devices are convenient, custom-fitted, medically supervised oral appliances that fit like a mouth guard and are easy to put in before bed and remove when you wake up, making nighttime sleep apnea treatment simple and comfortable.
How Standard Sleep Apnoea Devices Work
There are a myriad of Oral Appliances that have been used for many years to attempt to treat sleep apnoea. These devices address airway obstructions by only advancing the lower jaw or mandible. This can be an effective mode of therapy if the main issue is an obstruction arising primarily from the tongue base. Unfortunately, the tongue is often not the only issue. It is very common that there are other sites of obstruction such as the soft palate and side walls of the airway. Increased nasal resistance can also lead to large negative pressures in the airway which suck the airway shut. The result is often a switch to mouth breathing – leading to therapy failure. We can uniquely solve for this. Please read below to see how we can turn this type of failure into your treatment success.

The iHeart Sleep PEEP Guard Difference
PEEP Guard not only stabilise the lower jaw or mandible but can address all levels of obstruction and treat the entire airway. We do this by adding integrated air channel technology (PEEP Guard) and intra-oral positive end expiratory pressure (PEEP Shield). This increases effectiveness by up to 50% compared to standard appliances.
What is “PEEP Shield” and How Does it Make Oral Sleep Apnoea Devices More Effective?
PEEP Shield, or intra-oral positive end expiratory pressure, is a valve that is positioned inside the airway opening. It opens when breathing in to take advantage of the low resistance pathway and reduced collapsibility provided by iACT. It then partially closes when breathing out, increasing resistance and generating positive pressure similar to a CPAP. This further stabilises the airway. Together iACT and iPEEP regulate pressure and flow and harnesses the body’s own breathing to generate a CPAP-like result. Let your body be the CPAP.

Innovation & Growth in Sleep Therapy
The tailored therapy programme
What each addition resolved, step by step
A government-funded three-year CRC-P research programme escalated the same patients one step at a time, adding a mechanism only when the step before had not resolved their sleep apnoea. Everyone in it had already been failed by earlier treatment. The chart is that one group of patients.*
56%Appliance alone
63%+ air channel
80%+ EPAP valve
93%+ positional therapy
100%+ CPAP, lower pressure
Mandibular advancement
The mechanism in iHeart Sleep Basic
+ Integrated air channel
The mechanism added at PEEP Guard
+ Oral EPAP valve
The mechanism added at PEEP Guard Essential
+ Positional therapy
Not a device — part of the tailored programme
+ CPAP at lower pressure
For the last 7% — added to the appliance, and without a full face mask
One programme, in one group of people. It is not a prediction about any individual result — which is why treatment starts with an assessment.

| Addition | Level | Resolved here | Cumulative |
|---|---|---|---|
| Mandibular advancement | iHeart Sleep Basic | 56% | 56% |
| + Integrated air channel | PEEP Guard | 7% | 63% |
| + Oral EPAP valve | PEEP Guard Essential | 17% | 80% |
| + Positional therapy | Part of the programme, not a device | 13% | 93% |
| + CPAP at lower pressure | Added to the appliance, no full face mask | 7% | 100% |
Still Wondering If It’s For You?
Prior to scheduling an appointment with one of our certified Clinical Sleep Consultants or a Doctor, let’s determine if you noticing certain symptoms in order to be eligible for the iHeart Sleep personalized sleep therapy and treatment regimen.
