What is a Sleep Study?
A sleep study is a comprehensive observation and assessment of a person’s sleep to determine if they suffer from a sleep disorder such as the most common disorder Obstructive Sleep Apnoea (OSA). The study of sleep, medically known as a polysomnogram, is a non invasive process where data is recorded and analysed by a sleep specialist. If you believe you are not sleeping right, a sleep study may be a great way to help yourself learn more about your symptoms and sleep health.
In Australia we have 4 levels of sleep studies divided in two main groups, each appropriate for different circumstances and with various advantages and disadvantages.
- Level 1 Sleep Study – Overnight stay in a hospital or sleep clinic which tests for most types of non-respiratory and respiratory sleep disorders. This is the most comprehensive and considered the ‘gold standard’ in testing.
- Level 2 Sleep Study – Can be done from home or as an overnight stay, tests for the same respiratory sleep disorders but has less signals for non-respiratory disorders as it does not include manual observation.
Limited channel sleep studies
- Level 3 Sleep Study – Only done from home, this primarily tests for respiratory sleep disorders such as types of sleep apnoea. The most common at home test which does not require a referral from your doctor.
- Level 4 Sleep Study – The most basic test (two signals) only looks at cornerstone sleep apnea metrics; blood oxygen and pulse. This test is done at home and requires prescreening from both the patient and bed partner.
CPAP Online Australia offers the Level 3 Home Sleep Study which is designed to detect the presence and severity of sleep apnoea using 7 different sensors. We recommend patients start with this sleep study because it is sufficient to rule in a respiratory sleep disorder and is quick and easy and can be done in the comfort of your own home.
In order to detect other types of sleep disorders including non-respiratory, a Level 1 Sleep Test is required which can capture up to 16 channels of data. We recommend contacting your GP for a referral to a sleep specialist if you require more comprehensive studies on sleep.
Once a patient has completed a sleep study and has subsequently been diagnosed with obstructive sleep apnoea, the most effective treatment according to a 2018 report is Continuous Positive Airway Pressure therapy, commonly referred to as a CPAP Machine, will help patients to get a good night’s sleep and to live a longer and healthier life.
Did you know? A study showed 80% of men and 93% of women1 are living with the OSA sleep disorder but have not been diagnosed by a sleep study. To make matters worse, untreated Sleep Apnea can cause significant health complications and may even lead to premature death.
How to Test for Sleep Apnea
There are a number of measures you can take to determine whether you have sleep apnea – in addition to a number of sleep tests you can do from home or in a sleep lab, other tools such as online screening tests also help to determine the likelihood of sleep disorders.
Done from the comfort of your home, this in home sleep study makes the process of a home sleep test straightforward, fast and easy. This particular at home sleep study works through the use of a device overnight, allowing for the evaluation of your current sleep health.
If you are wondering what you have to do to get a sleep apnoea test out of the way, it is as simple as ordering the home sleep study, following the included instructions and completing the sleep study at home, and returning the device in the provided reply-paid envelope.
How Much Does a Sleep Study Cost in Australia?
As the home of the invention of the CPAP machine, top companies such as ResMed manufacture machines and other CPAP equipment in Australia. If you are interested in completing a sleep study, Australia offers great prices that will allow you to determine whether you have sleep apnea.
The CPAP Online Australia sleep study is priced at a low one time price of $90, including free return shipping. This low pricing is to ensure that testing for sleep apnoea is as accessible as possible, and that we can help patients to address their symptoms conveniently and quickly.
What Happens at Sleep Study Consultations?
Once you have completed your sleep apnea test at home and returned the device, you will receive results that outline whether or not you need to consider sleep test apnea treatment. If home sleep test results indicate that treatment may be effective in managing symptoms and improving your health, getting help with the approach of using a CPAP machine is the most popular option, and is extremely effective in treating symptoms of sleep apnoea.
