What is a sleep study?

A sleep study is a complex neurophysiological medical test. The recording is conducted as part of an overall evaluation to look at what is happening during your sleep. Many things are recorded including brain wave activity (EEG), muscle tone (EMG), heart rate (ECG), breathing patterns, oxygen levels, leg movements and video of abnormal movements and behaviours.

A sleep study conducted at Warringal Private Hospital’s sleep laboratory involves an overnight stay, where patients arrive in the early evening and go home on waking up in the morning.

Our sleep laboratory is a carefully controlled environment, with measures to control noise, light and electrical interference. In the evening, our technicians will apply the electrodes / sensors and continuously monitor all the signals collected.

Once a sleep study has been performed, the data recorded is manually analysed by a senior scientist.

Why have a sleep study?

Most of us spend around a third of our life sleeping, so it may not surprise you that a sleep disorder can have a significant negative impact on a person’s life and their health (not to mention the impact on their partner).

Obstructive Sleep Apnoea (OSA) is the most commonly diagnosed sleep disorder yet many are unaware of their condition. It is categorised by have repeated episodes of partial or complete obstruction of the throat (also known as "pharynx" or "upper airway") during sleep. A narrow floppy throat is also more likely to vibrate during sleep, which causes snoring. If partial or complete obstructions occur breathing is reduced or stops for a short time – from 10 seconds up to a minute or more – and blood oxygen levels fall as a result. A brief interruption to sleep (an arousal) that lasts for as little as 3 seconds then occurs, allowing breathing to start again but your sleep is disrupted as a result. These episodes of obstruction may happen many times – even hundreds of times - overnight. Some people know that their breathing is not normal at night, but may be unaware that this is a medical problem that is causing them harm. Risk factors linked to OSA include being older, overweight and a family history of severe snoring or OSA.

There is strong evidence that people with untreated moderate to severe OSA have other health problems. There is evidence that having OSA, particularly if severe, may increase the risk of diabetes, hypertension, heart attack, stroke or depression. Treating sleep apnoea may reduce these risks.

People with OSA are approximately two and half times more likely to have a motor vehicle accident than others. Broken night-time sleep leads to less alertness, slower reaction times, poorer concentration and more chance of falling asleep at the wheel. The risk of work accidents is increased if your job involves operating machinery or transport.

Arranging the Sleep Study

Study requests are welcome from specialists and general practitioners*.

A sleep study can be arranged following consultation with a Sleep Physician OR via direct referral by your General Practitioner (GP).

A list of our Sleep Physicians can be found below.

Download the request form and take it to your next GP appointment and discuss your symptoms with them. To save time, feel free to complete as much of the request form prior to your doctor’s appointment. Ensure that the doctor completes their details and faxes / emails the form to us.

Once your referral has been received and reviewed by one of our sleep physicians, you will be contacted to arrange a date for your sleep study and an information pack will be sent.

Following your sleep study, a review appointment with one of our qualified sleep physicians will also be arranged for you to discuss the results and treatment options.

*All referrals are reviewed by one of our sleep specialists before bookings are made.
