Preparing for a sleep study

What to expect and how to prepare for a sleep study in hospital

Understanding your procedure: What is a sleep study?

A sleep study helps to diagnose sleep disorders, for example, sleep apnoea. During a sleep study, doctors measure your brain and body activity to check your sleep cycles.

What can a sleep study diagnose?

Sleep studies can be used to diagnose a range of sleep disorders, including: 

  • Sleep-related breathing disorders, for example sleep apnoea. Conditions where your breathing momentarily pauses and then restarts while sleeping.  
  • Limb movement disorder (also known as restless leg syndrome). Where you are unable to stop moving your legs while sleeping. 
  • Parasomnias. A range of sleep disorders that include sleepwalking and sleep  terrors. 
  • Narcolepsy. Symptoms can include extreme tiredness during the day, and sudden episodes of sleep.  

Sleep studies can also be used to develop a treatment plan. For example, a sleep study done with a Continuous Positive Airway Pressure (CPAP) mask to test its effectiveness at improving your sleep apnoea.  

Sleep studies for children

Sleep disorders are also common in childhood. In certain situations, children may be referred to a specialist for further investigation using a sleep study. You can read more about children going to hospital here

What happens during a sleep study? 

During a sleep study, doctors collect data about your brain activity, breathing, heart rate and movement using sensors. 

A sleep technician attaches these sensors before you go to bed. The sensors shouldn't hurt, but some people find them uncomfortable or restrictive because of the cords attaching sensors to a central box. You will still be able to turn over in bed, but you may need to call the technician if you need to use the bathroom. 

Overnight, the sleep technician monitors you using a special camera to make sure none of the sensors come off. While some people may find the situation or sensors uncomfortable, many people find they only take slightly longer to fall asleep, and there is still enough data collected to make a diagnosis. 

In the morning, the sleep technician removes the sensors, and you will be discharged.  Your results will be reviewed by the technician and your specialist and discussed with you at your follow up appointment. 

Preparing for a sleep study

While sleep studies are usually conducted in hospitals and clinics, they are not an invasive procedure which means they only require minor preparation. 

Call us on 132 331 before booking in a sleep study. We can check your cover and provide advice to help reduce your out-of-pocket costs. It’s also important to note, that we only pay benefits for inpatient services (where you are admitted to a hospital as a private patient) and the service is included in your cover.

Ask your specialist and hospital about any out-of-pocket costs you might have. They should provide it to you in writing and, if you agree, this is known as Informed Financial Consent.

A week before:

If you haven’t already, should speak with your treating team to:

  • Confirm date and time
  • Confirm whether it’s ok to take your regular medications on the day, and what time you should take them
  • Check about body hair, which may need to be clean shaven for the electrodes to make contact and adhere to the skin
  • It is also worth organising transport to and from the clinic or hospital, including parking options if you plan to drive yourself. 
  • On the day: 
  • Keep to your regular routine
  • Avoid alcohol or caffeine 
  • Avoid afternoon napping
  • Avoid using any lotions on your skin or hair which may prevent the sensors sticking to your body. 

What to pack: 

  • Your appointment letter
  • Your normal medications (either in their original boxes or with a list of the dose and when you take them)
  • Your Medicare and Medibank cards
  • Loose, comfortable clothes that button at the front
  • Clean clothes for the following day
  • Non-slip shoes or slippers
  • Toiletries
  • Mobility aids (put name labels on if you are able)
  • Visual or hearing aids (don’t wear contact lenses) 
  • A pillow (optional)
  • Entertainment - something to do or read during your stay (you may or may not have a television) 
  • Your mobile phone and charger
  • Your CPAP machine (if you have one) 
  • Do not bring money or valuables such as jewellery.

Recovering after a sleep study 

Given the nature of sleep studies, most people return to normal life after discharge. Some people may experience minor skin irritation from the sensors. Speak to your specialist if you are concerned.
