Overnight sleep study
Overnight sleep studies are carried out at your hospital or sleep clinic. Sensors will be attached to your body to record information while you sleep overnight in the clinic. This is a non-invasive and painless procedure.
What is it?
An overnight or in-lab sleep study is conducted by highly trained sleep professionals who monitor your sleep using sensors that record information. A non-invasive and painless procedure, patients spend the night away from home in a hospital or clinic under our professional care. Results are generally available within approximately 10 working days of the study through your regular GP and will help determine a course of action to improve your quality of sleep.
Conducted in hospital or clinic
Sensors used to monitor sleep patterns
Non-invasive and painless
If you are having trouble with sleeping and getting enough rest during the night, your doctor may refer you to a sleep professional to investigate the cause. Your sleep specialist can identify contributing factors and diagnose a number of sleep disorders.
If you have been diagnosed with sleep apnoea, your specialist may recommend a CPAP (continuous positive airway pressure) study. This involves pressurised air being gently pumped through a mask that covers your nose and/or mouth. The air pressure is monitored and adjusted during the study to prevent snoring, apnoea, other breathing irregularities and improve blood oxygen levels and sleep quality.
For some sleeping disorders, your specialist may recommend a test using a BiLevel device. As with the CPAP study, a BiLevel device pumps pressurised air through a mask that covers your nose and/or mouth, but delivers different pressure settings for breathing in and breathing out. This allows sleep specialists to gather specific information to assist with treatment options.
- Overnight sleep studies require you to spend the night at your hospital or sleep clinic under the care of a sleep professional.
- The procedure requires sensors and leads to be attached to different parts of your body to record information, along with audio-visual and body-position monitoring while you sleep. It is non-invasive and painless.
- The overnight stay generally lasts approximately 12 hours (usually from 7:00pm to 7:00am) – however may vary between clinics.
- Our team of highly trained sleep technicians, nurses, scientists and physicians use the information gathered to identify and investigate any issues during your sleep and how they may affect your body. Someone is available throughout the night should you need assistance or have any concerns.
How should I prepare?
Stick to your normal routine on the day, including eating and drinking as usual (including tea and coffee or other caffeine-based stimulants)
Take all regular medications as prescribed unless advised otherwise by your doctor
Shower, shampoo and dry your hair to help with adhesion of sensors to your skin and scalp
Remove any make-up, hair pieces and nail polish, and refrain from using other hair and skin products and moisturisers
Bring your usual sleepwear and toiletries with you, and a favourite pillow if you like
Have an evening meal before your arrival
Ensure you read all the preparation information prior to your test
Confirm your appointment at least 48 hours prior
What happens next?
The study is analysed at our laboratory and reviewed by our qualified team of sleep professionals. Results will be available within 10 working days through your referring doctor or specialist and they will be able to assist with planning any treatment that may be recommended.
