What are they used for?

A sleep test may be recommended if you:

  • Feel constantly tired or sleepy during the day or fall asleep at inappropriate times.
  • Have abnormal oxygen levels.
  • Have high carbon dioxide levels.

Sleep tests are normally carried out using a monitor, which you wear overnight at home.

What to expect

You will be asked about your symptoms and any medication you are taking. A clinician will measure your height and weight and calculate your body mass index.

  • Respiratory sleep test: During the test, you will be connected to a monitor that will record your breathing, oxygen levels, heart rate and snoring while you sleep. If your doctor wants to test your carbon dioxide levels you will be asked to wear a small clip in your earlobe and be give a blood gas test when you wake up.
  • Polysomnography: If basic tests don’t provide clear results, you may be referred for a polysomnograph, which is a more complex test used to measure brain waves, eye movements, muscle movements, breathing and heart activity. You will be connected to a monitor while you sleep. If you have problems staying awake during the day you may be asked to stay awake as long as you can while sitting in a quiet, semi-darkened room.

Before your test someone from our team will personally contact you by telephone to give you information about what to expect and how to prepare.

What can they diagnose?

Sleep tests may be used to diagnose:

  • Snoring and obstructive sleep apnoea (OSA) – obstruction of the airway during sleep, which can cause you to stop breathing for 10 seconds or more. This repeated rousing from sleep can lead to excessive daytime sleepiness, forgetfulness and mood changes, as well as depression and anxiety.
  • Other common and less common respiratory disorders.

Other tests may also be used to determine the cause of your symptoms.
