Sleep Apnoea Tests

Home based sleep tests are used for the diagnosis of obstructive sleep apnoea in people with a high probability of having moderate to severe obstructive sleep apnoea and those who do not have certain serious medical conditions.

How to Refer

Download and print the referral form using the link below. Fill out all the sections, including the questionnaires on page 2 which are required to determine the probability of sleep apnoea prior to conducting the test.

Preparing for the test

At Sleep Australia, patients are seen by qualified Sleep scientists who set up the test at one of our office locations. The appointment takes one hour.

About the test

Home based sleep tests use virtually identical sensors and recordings as the laboratory test but the difference is that you will sleep in the comfort of their own home wearing the portable equipment.

It is a non-invasive test, which records data from seven sensors:

  • Brain waves
  • Oxygen levels
  • Heart rhythm
  • Chest breathing expansion
  • Leg movements
  • Body position
  • Snoring

CPAP Therapy

Continuous Positive Airways Pressure (CPAP) is a medical device, which is used for the treatment of obstructive sleep apnoea. This device is widely used, as it is an effective form of therapy and well tolerated by most people. Modern devices are compact, quiet, and minimally intrusive with advances in face mask technology.

Starting Therapy

The Sleep physician will review the data from your sleep study and make recommendations on therapy options. You will have the opportunity to discuss your results with the doctor and select the most suitable therapy, based on both effectiveness and patient preference.

If CPAP therapy is to be commenced, Sleep Australia will refer you to the appropriate provider where a Sleep Scientist can adjust the pressure and select the best mask (full face or nasal) to keep the airway open. Alternatively, an “auto” device with a self-adjusting pressure is used to commence treatment and set the optimal pressures.

The choice of therapy ie CPAP/BiPAP depends on the Sleep Physician’s assessment in conjunction with the patients’ needs and goals.

While the treatment may seem uncomfortable, noisy, or bulky at first, most people accept the treatment after experiencing better sleep.

MAS Therapy

Mandibular Advancement Splint (MAS), also known as an oral appliance, can be used to treat mild to moderate OSA as an alternative to CPAP therapy.

The device is worn at night and prevents the tissues at the back of the throat and base of the tongue from collapsing into the airway. The device also repositions the jaw (mandible), bringing the tongue and soft palate forward. In some people this is a very effective method of relieving airway obstruction. These devices are custom made from comfortable, high strength acrylic material by Dentists specialising in sleep medicine.

If the Sleep Physician recommends this, a referral will be made to a Dental team that specialises in MAS. After a series of consultations and fittings, a custom made device is made for individual patients to best manage their symptoms.

Positional Therapy

Positional therapy adjusts sleep position (to stay off the back) may help improve sleep quality in people who have sleep apnoea when sleeping on the back for most of the night.

“Nightshift” is a positional therapy device, which is worn on the back of the neck; it begins to vibrate when you start to sleep on your back. It waits 15 minutes before beginning its tracking, giving you time to fall asleep naturally in whatever position you find comfortable.

Through continual use, your body learns to respond to smaller and smaller vibrations and minimizes the amount of time spent on your back or trying to roll there.

Data from the device can be downloaded to monitor the effectiveness of the therapy and its improvements on your sleep quality. Trials have shown a significant reduction in the volume of snoring and the amount of back sleeping when using the device.

Provent Therapy

Provent therapy is an alternative therapy for snoring and mild obstructive sleep apnoea and upper airway resistance. It consists of adhesive nasal valves that are applied externally to each nostril during sleep. It uses Expiratory Positive Airway Pressure (EPAP) to stabilise the upper airway.

Insomnia and Fatigue Management


Our Sleep Physician will take a detailed history of your sleeping history, daytime symptoms, medication, work pattern etc. This will help us to better understand the nature of your insomnia (sleep maintenance which is staying asleep or sleep initiation which is falling asleep) as well as likely underlying causes. A detailed questionnaire as well as sleep diary is usually helpful.

In some cases, people do need special sleep tests, such as a sleep apnoea test or actigraphy.

Actigraphy records activity and movement with a motion detector that is usually worn on the wrist. The test is done at home, over a specified number of days and nights. It will record how much you actually sleep and when. This is a useful test in the evaluation of insomnia and in circadian rhythm disorders.


Management of insomnia and fatigue may involve:

    • Treatment of underlying Sleep Disordered breathing such as sleep apnoea or restless legs syndrome
    • Sleep hygiene education
    • Lifestyle modification including relaxation techniques
    • Management of underlying anxiety, depression or other mental health issues, chronic pain
    • Cognitive Behavioural therapy for Insomnia: This includes stimulus control, sleep restriction, relaxation training, sleep hygiene and cognitive therapy. Cognitive therapy within CBT-I is not the same as versions of CBT that are not targeted at insomnia. When dealing with insomnia, cognitive therapy is mostly about offering education about sleep in order to target dysfunctional beliefs/attitudes about sleep.
    • Light therapy: This is an effective therapy for people who have a condition called delayed sleep phase syndrome (DPSD). People with this disorder have a problem with their body’s “sleep clock” such that they have a difficult time falling asleep until much later in the evening or night than they wish (and therefore wake up later than they wish in the next morning). Exposure to bright light at specific times helps to realign the body’s sleep clock.
    • Medication changes: Medicines may be recommended in certain conditions or there may be certain medications that may best be discontinued, after detailed review by the Sleep Physician especially if insomnia interferes with your ability to function during the daytime

Respiratory Function Tests

Spirometry (~20 minutes)

Spirometry is a test that measures the the maximum amount of air a person can breathe out (after taking a deep breath in), as well as how much a person can breathe out in one second. This test can identify airway obstruction and help to diagnose certain lung conditions. Since sleep apnoea is associated with upper airway obstruction, all patients undergoing a home-based sleep study will have a spirometry performed.

On the day of the test: avoid smoking.
24 hours before the test: avoid short-acting bronchodilators (Ventolin, Bricanyl, Atrovent, etc) for 8 hours and long-acting bronchodilators (Breo/Anoro Ellipta, Serevent, Symbicort, Theophylline, Seretide, etc).

Comprehensive Lung Function Tests (1 hour)

This is a series of breathing tests including measures of airway obstruction, lung volumes and diffusion capacity which help to identify disorders of the airways and lung tissue.

On the day of the test: avoid smoking.
For 24 hours before the test: avoid short-acting bronchodilators (Ventolin, Bricanyl, Atrovent, etc.) for 8 hours and long-acting bronchodilators (Breo/Anoro Ellipta, Serevent, Symbicort, Theophylline, Seretide, etc).
