What does the Aer Healthcare sleep study look like and why are we the best?
We are the best because we don't just give you a number (AHI score), we give you advice on what type of therapy is best based on advanced calculations from the sleep test data. No other sleep lab does this.
Additionally, we don't just tell you that you grind your teeth, we also tell you how any tooth grinding you do may be affecting your sleep.
The images below what the sleep study looks like when it's fully set up.
Full instructions (written and video) will be provided to you for your sleep study.
How will I be able to sleep with the sleep study equipment on?
You're not the only one to ask this.
The reality of our sleep is that we only remember when we're awake, not when we're asleep. The thousands of sleep studies we've done prove that everybody sleeps with all of this equipment on.
In fact, when asked, 90% of our patients state that they will repeat the sleep test in 12 months.
What types of sleep studies are available for in home use?
The only types of sleep tests availble for use in your home are type 2 and below. Type 1 testing is only available in a clinic or hospital environment and is only needed for serious medical conditions that are more complex than obstructive sleep apnoea (OSA).
More than 95% of sufferers of OSA are well serviced and have their issues funtionally diagnosed by a type two sleep test at home.
The definition below is what most people will see when they google sleep tests.
What are type I, II, III, and IV sleep tests?
Type 1 and 2 tests collect more detailed data (sleep lab or hospital-based polysomnography is a type 1 sleep test). Home sleep tests are generally type 3 or 4 tests because they collect less data and and are not capable of identifying patterns of sleep versus wake.
This definition is universally misleading becuase in Australia we CAN use type 2 tests at home due to our governmental policies.
What is a type 2 sleep study and why do I need it instead of a more simple test (lower level type 3 or 4)?
If you’ve been feeling tired and don’t know why, you deserve more than just a basic diagnosis. You deserve the full picture to get the right treatment.
Our Type 2 Home Sleep Test (HST) is unique to Australia and Medicare-rebated, meaning you pay just $199 after the rebate. This is the only home test approved by Medicare to provide a comprehensive and accurate diagnosis of your sleep.
Why settle for less?
Most “home sleep tests” available online in Australia are actually Type 3 or Type 4 tests, which are significantly less reliable. These tests, such as WatchPat, Somfit, and Sunrise (Type 4), only measure a limited range of sleep signals, leaving important data uncollected. This means they cannot give you a full evaluation of your sleep and may miss crucial issues that require proper treatment.
In contrast, our Type 2 Home Sleep Test provides a complete assessment of your sleep, including all the necessary signals for a thorough evaluation. This includes full monitoring of your breathing patterns, oxygen levels, heart rate, and sleep stages, which are essential for accurately diagnosing sleep disorders like sleep apnea.
The result? A more accurate diagnosis and clearer recommendations for therapy based on your unique needs, not just a quick, partial test.
When you choose our service, you're not just getting a test—you're getting a comprehensive evaluation from a certified sleep physician, who will guide you on the most effective therapy options available, tailored specifically to you. You won't just be left wondering why you're tired—we provide the answers you need to improve your quality of life.
What does our sleep report cover that you will not get from any other Sleep Test service in Australia?
If you have ever undergone a sleep test, or you know someone who has, you may have heard of the AHI number and how scary that can look. Say a number like "30 events per hour" or "I stopped breathing 100 times in night..."
The AHI or RDI mean two things.
The AHI is the number of times per hour you STOP breathing (apnoeas) counted up with the number of times you have more trouble breathing but do not stop (hyponeas).
The RDI has the above events in it, plus another type, RERA, which is determined to be trouble breathing, but not to the level of a hypopnea.
These results are not tellling you anything that will relate to what kind of therapy you need as they are just numbers.
Why is this important?
Other companies use these numbers to force you to use CPAP when you may not actually need it. Our sleep study report empowers you to make an informed decision about your therapy pathway based on research-backed calculations within the report.
We can determine what level of collapsibilty your airway suffers while you sleep.
No matter what the AHI or RDI scores add up to, we break down what that means and we can tell you what kind of therapy will be best for you. This means we can tell you if a CPAP or a Mandibular Advancement Splint (MAS) will actually help you or not, based on our exclusive analysis.
For example, if you have an RDI score of 15 events per hour, we will tell you if this is a more collapsible score than someone else with that same score, by analysing the data more carefully than other services.
This could mean the difference between what kind of recommendations you will receive from our sleep specialist, and what we also identify and recommend you look into as a result of this test.
Better service for less money with more value.
Better treatment options explained more carefully.
What is Bruxism, and why is this in my report?
Bruxism is loosley defined as tooth grinding.
This is a habitual activity, and at night bruxism manifests in combination three main types of activity.
Sleep bruxism occurs when the airway muscles need to be reset so that you can breathe more effectivley and avoid airway collapse. The body only adjust the airway muscles voluntarily during wake. This makes you more tired during the day, and without this analysis, you may not best understand why you are tired.
Nocturnal bruxism is different, this can happen as a result of your awakenings due to airway events or simple snoring. This type of tooth grinding can happen in light sleep and during the cross over to wake. We manually score all these events to correctly account for when they are happening.
The last kind of bruxism is rare. This is REM (dreaming sleep) behaviour disorder bruxism. As the name suggests, this bruxism occurs during REM sleep, when your muscles should not be active. This type of bruxism affects 12.8% of the population.
Noting bruxism at night can shed light on the cause of your tooth wear, breakage and jaw pain.
By testing for tooth grinding (bruxism) at night, your dental team can use this report to accurately construct a strategy on avoiding the effect of this type of nocturnal destructive and disruptive activity into your future.
What does Aer Healthcare's sleep study measure?
Electroencephalogram (EEG): monitors brain waves
We use bilateral frontal EEG channels, F3 and F4, positioned on the forehead.
If a system is not using correct EEG derivations, it cannot stage sleep accurately. Algorithms alone do not stage sleep — physiology does.
Electrooculogram (EOG): monitors eye movements
We use true electro-oculography, with E1 and E2 electrodes positioned near the eyes.
This allows accurate detection of REM sleep, which is essential for identifying REM-dependent apnoea, parasomnias, and proper sleep architecture.
Electrocardiogram (ECG): monitors heart rhythm
We use dual-lead ECG — left and right chest.
That means we don’t just record beats per minute; we assess heart rhythm, variability, and irregularities where clinically relevant. A pulse signal is not an ECG.
Respiratory and Abdominal Effort
We use both thoracic and abdominal effort belts.
Importantly, we look for paradoxical breathing, which helps distinguish obstructive from central events and understand how the airway is collapsing — not just whether an event occurred.
Pulse Oximeter: monitors oxygen levels
Finger-based pulse oximetry, where it is most accurate.
We measure oxygen saturation and pulse with waveform verification — not wrist-based estimates.
Limb Movement and EMG
This is a major point of difference that we offer.
Instead of relying solely on leg accelerometers, we use advanced electromyography (EMG):
EMG at the lower labial commissure to monitor mouth posture and support REM detection when combined with EEG and EOG
Bipolar EMG on both masseter muscles to detect bruxism, jaw clenching, and grinding
These signals detect parasomnias more accurately and differentiate muscle activity from simple movement.
Many providers don’t even specify how limb activity is detected — which lacks transparency.
Nasal Airflow & Snoring
We use true nasal airflow measurement, analysing breath-by-breath physiology — not inferred airflow based on algorithms.
Snoring is interpreted in context of airflow restriction and recovery, not just sound.
Position Sensor
Yes — continuously monitored and correlated with respiratory events.
What distinguishes Aer Healthcare's sleep study from other providers?
Two things.
First: interpretation.
We don’t just count events; we assess how severe they are for that individual.
Second: advanced analysis.
We apply researched mathematical modelling to estimate upper airway collapsibility (Pcrit). That helps determine whether a patient is more likely to respond to:
Mandibular Advancement Splints (MAS)
CPAP therapy
Nasal or airway surgery
Combination or adjunctive therapies
So we don’t just send a report — we deliver a diagnostic decision-making tool with treatment recommendations.
