Services we provide

Overnight diagnostic sleep studies

This is the most common type of sleep study performed, where tiny sensors are used to measure the body's physiological processes during sleep. Diagnostic polysomnograms (PSGs) are used to diagnose snoring, obstructive sleep apnoea, periodic limb movement disorder, sleep-state misperception, and other less common sleep disorders; they can also be very helpful in investigating insomnia, narcolepsy, idiopathic hypersomnolence and restless limb syndromes.

Many of SNORE Australia's attended sleep-laboratories use infra-red digital video technology to enable recording of abnormal limb movements, fits or seizures, and abnormal behaviours during sleep.

Daytime diagnostic sleep studies

Daytime diagnostic sleep studies similar to overnight PSG can be performed in individuals who normally sleep during the day (such as shift-workers).

CPAP Titration sleep studies

In patients whom CPAP treatment is recommended, a CPAP-titration study is used to determine what CPAP pressure is required to control snoring and obstructive respiratory events optimally. SNORE Australia uses leading CPAP equipment for these pressure titrations. Tiny sensors similar to those used during a diagnostic sleep study are also used during a CPAP-titration study.  We perform only manual CPAP titration studies (some other sleep laboratories and home study services only perform "Autoset" titration studies, which we believe are considerably inferior.

BPAP (VPAP) and APAP Titration PSG

Otherwise similar to CPAP-titration studies, these types of PSG studies involve the use of bi-level positive airway pressure (BPAP, also called variable Positive Airway Pressure – VPAP) or Automated Positive Airway Pressure (APAP) technology to treat OSA.

Multiple Sleep Latency Test (MSLT)

An MSLT is a specialised daytime sleep-study used to investigate narcolepsy and hypersomnolence (excessive daytime sleepiness). MSLTs are generally performed during the day, immediately following an overnight PSG. The test involves 4 or 5 nap periods at 2-hourly intervals throughout the day. Brain waves and eye movements are recorded to enable sleep-times and sleep-stages to be determined.

Maintenance of Wakefulness Test (MWT)

This test is used to assess a patient’s ability to maintain wakefulness throughout the day. This test is helpful in assessing the efficacy of an individual's treatment for sleep-disorders and driving safety. MWTs are generally performed during the day, immediately following an overnight PSG. It involves four, 40-minute test periods at 2-hourly intervals, throughout the day. Patients are required to stay awake throughout each test period (brain waves and eye movements are recorded to enable wakefulness and sleep-states to be determined).

MWTs are helpful in assessing how effective treatment for a sleep-disorder is (e.g., CPAP for obstructive sleep apnoea, or stimulant medication for conditions of excessive daytime sleepiness). 

Electroencephalograms

SNORE Australia offers full 28-channel EEGs in parallel with all overnight and daytime sleep-studies in patients with suspected epilepsy, nocturnal seizures, fits or 'funny turns'. EEG facilities include time-linked digital video recordings, so that convulsions or other abnormal movements during sleep can be recorded and analysed.  All EEGs are reported by experienced Consultant Neurologists.

EEG examinations are also performed during the day at some of our laboratories.

Nerve conduction studies

A nerve-condution study is a neurological test of the nerves.  It involves sending small electric signals through nerves and assessing the nerve response with small electrodes placed on the skin.  This test is commonly used to assess carpal tunnel syndrome, peripheral neuropathy, ulnar nerve problems, "trapped nerves" and all other peripheral nerve-disorders.  

When appropriate, EMG (electromyography) studies may be performed.  This involves measuring nerve-signals using a tiny needle-electrode. 

Nerve conduction studies and EMG tests are performed by Dr John Corbett  & Associates Neurology Group at some SNORE Australia locations.  Click here to visit Dr John Corbett & Associates Neurology Group website.

Clinical advice and management

Every sleep study report prepared by SNORE Australia is individually prepared by experienced sleep study analysts and qualified senior technologists, credentialed by the Board of Registered Polysomnographic Technologists (BRPT). Every sleep study is personally reviewed by our Credentialed Sleep Physicians, Dr John Corbett and Dr Sean Tolhurst.

Clinical consultations with our Sleep Physicians are available in some areas with a referral. For more information, telephone our administration centre on 5557 0055 (or 1800 076 673).  Alternatively, we also accept correspondence via email at snore@snoreaustralia.com.au or use the online form on the Contact Us page here.
