Sleep Apnea Basics
What is sleep apnea?
Sleep apnea (also commonly spelt sleep apnoea in Australia) is a common sleep disorder where breathing repeatedly stops or becomes shallow during sleep. It affects thousands of Australians and is a leading cause of poor sleep quality, loud snoring, and daytime fatigue.
These pauses in breathing, known as apneas, occur when the muscles in the throat relax and partially or completely block the airway. When this happens, the brain briefly wakes you — sometimes with a snort, choke, or gasp — so normal breathing can resume. Even if you don’t fully wake up, this constant disruption prevents deep, restorative sleep.
Types of Sleep Apnea
If left untreated, sleep apnea may increase the risk of high blood pressure, heart disease, stroke, type 2 diabetes, and difficulty managing weight.
Early diagnosis and treatment — often using CPAP therapy — can dramatically improve sleep quality, energy levels, and overall health.

How is sleep apnea diagnosed in Australia?
Sleep apnea is diagnosed through a sleep study, also known as a sleep test, which monitors your breathing, oxygen levels, heart rate, and sleep patterns overnight.
In Australia, many people are diagnosed using a home sleep apnea test, which is a convenient and cost-effective way to assess for obstructive sleep apnea (OSA) from the comfort of your own bed. These tests typically involve wearing a small monitoring device while you sleep.
In some cases, a more detailed in-lab sleep study (polysomnography) may be recommended. This is conducted in a sleep clinic or hospital and provides a more comprehensive analysis, particularly for complex cases or suspected central sleep apnea.
Once the results are reviewed by a healthcare professional, you’ll receive a diagnosis and severity rating (mild, moderate, or severe sleep apnea). From there, appropriate treatment options can be recommended — most commonly CPAP therapy, which is considered the gold standard for treating obstructive sleep apnea.
Early diagnosis is important, as untreated sleep apnea can significantly impact your sleep quality, energy levels, and long-term health.
Do I need a referral for a sleep study?
Do I need a referral for a sleep study?
In most cases, yes — a referral from a GP or specialist is required to complete a formal sleep study in Australia, particularly if you are claiming through Medicare or using a sleep clinic.
However, some providers offer home sleep apnea tests that may be available without a referral, depending on your situation. These can be a faster and more convenient option for people experiencing symptoms like loud snoring, daytime fatigue, or suspected obstructive sleep apnea (OSA).
If you’re unsure where to start, speaking with your GP is usually the best first step. They can assess your symptoms and refer you for the most appropriate type of sleep study.
If you already have a referral, we can assist with coordinating your sleep study, interpreting your results, and guiding you through the next steps — including CPAP therapy if treatment is recommended.
What can I do about treating sleep apnea?
What can I do about treating sleep apnea?
Treating sleep apnea starts with an accurate diagnosis, usually through a sleep study arranged by your GP or a sleep specialist. This helps determine whether you have sleep apnea and how severe it is, so the right treatment can be recommended.
For most people with obstructive sleep apnea (OSA), the most effective treatment is CPAP therapy. This involves using a CPAP machine and mask to deliver a steady flow of air, keeping the airway open during sleep and preventing breathing interruptions.
If treatment is recommended, a CPAP trial is often the next step. During the trial, you’ll be guided through selecting a suitable CPAP machine and mask, ensuring the right fit, and assessing how comfortable and effective the therapy is for you.
Once you’ve found the setup that works best, you can move forward with purchasing your own equipment. Ongoing support, equipment guidance, and follow-up care can make the transition to long-term CPAP therapy smoother, more comfortable, and more effective.
In some mild cases, additional options such as lifestyle changes or oral appliances may also be recommended, depending on your individual needs.
What is a normal AHI?
What is a normal AHI?
The Apnea Hypopnea Index (AHI) measures how many times your breathing stops or becomes shallow per hour of sleep. It is one of the key results used to diagnose and assess the severity of sleep apnea.
A normal AHI is generally considered to be fewer than 5 events per hour. Higher AHI levels indicate increasing severity:
- AHI under 5: Normal or well-treated sleep apnea
- AHI 5 to 15: Mild sleep apnea
- AHI 15 to 30: Moderate sleep apnea
- AHI over 30: Severe sleep apnea
If you have been diagnosed with sleep apnea, treatment such as CPAP therapy is often recommended to help reduce your AHI to within the normal range. Lowering your AHI can significantly improve sleep quality, energy levels, and overall health.
Is it spelled sleep apnea or sleep apnoea?
Is it spelled sleep apnea or sleep apnoea?
Both spellings are correct and refer to the same sleep disorder. “Sleep apnea” is the American English spelling, while “sleep apnoea” is the British English spelling.
In Australia, both terms are widely used and understood, although “sleep apnea” is becoming more common in online searches and medical content. Because of this, you may see both spellings used across websites, clinics, and CPAP-related information.
Regardless of spelling, both terms describe the same condition where breathing repeatedly stops or becomes shallow during sleep. If left untreated, sleep apnea may require treatment such as CPAP therapy to help keep the airway open and improve sleep quality.
Getting Started
What is a CPAP machine?
What is a CPAP machine?
A CPAP (Continuous Positive Airway Pressure) machine is a commonly used and highly effective treatment for obstructive sleep apnea (OSA). It works by delivering a gentle, steady stream of pressurised air through a mask worn during sleep.
This airflow keeps the airway open, helping to prevent the pauses in breathing that occur with sleep apnea. As a result, users typically experience fewer interruptions during the night, improved oxygen levels, and better overall sleep quality.
CPAP therapy is considered the gold standard treatment for moderate to severe sleep apnea and is widely recommended by sleep specialists in Australia and worldwide. With consistent use, many people notice improvements in energy levels, concentration, mood, and long-term health outcomes.
CPAP machines are available in different models and mask styles to suit individual comfort and sleeping preferences, making it easier to find a setup that works for long-term use.
Do I need a CPAP machine?
Do I need a CPAP machine?
A CPAP machine is typically recommended for people diagnosed with moderate to severe obstructive sleep apnea (OSA) following a sleep study. However, whether you need CPAP depends on your symptoms, diagnosis, and overall sleep study results.
Common signs that you may need CPAP therapy include:
- Loud, persistent snoring
- Waking up gasping or choking during sleep
- Excessive daytime tiredness or fatigue
- Morning headaches
- Poor concentration or brain fog
A formal diagnosis is required through a sleep study, which measures your breathing, oxygen levels, and sleep patterns overnight. Once results are reviewed by a sleep specialist, they will determine whether CPAP therapy is the most suitable treatment for you.
If CPAP is recommended, it is considered the gold standard treatment for sleep apnea, helping to keep the airway open during sleep and significantly improve sleep quality and overall health.

How can I get started with sleep apnea treatment?
Getting started with sleep apnea treatment usually involves a simple step-by-step process that begins with your GP and leads through diagnosis to treatment options such as CPAP therapy.
The typical process includes:
- Visit your GP for an initial assessment and referral
- Complete a diagnostic sleep study (either at home or in a sleep clinic)
- Review your results with a sleep specialist or healthcare provider
- Begin a CPAP trial if obstructive sleep apnea (OSA) is confirmed
- Select the most suitable CPAP machine and mask based on comfort and effectiveness
- Continue with ongoing support, follow-ups, and adjustments to optimise your therapy
Once treatment begins, most people notice improvements in sleep quality, energy levels, and daytime alertness as their therapy is refined over time.
