Sleep (Polysomnogram) Study

A sleep study is an investigation into the activity of the body during sleep. It is non-invasive, and it is carried out overnight to investigate the nature of sleep disorders using devices connected to the subject. 

Sleep studies are also used to monitor the progress of a patient to treatment.

What to expect during a Sleep Study?

A sleep technician will assign a room to the test subject to give time to acclimatise. Just before bedtime, a device is strapped to the patient's chest, and the device's sensors are connected to different parts of the body to monitor breathing, oxygenation, etc. while the patient sleeps. By morning, the device and its sensors are removed. Then the results are interpreted to the patient by a sleep doctor, who determines if the patient has a sleep disorder.

With the patient’s permission, staff may also request to film the sleep study to gain more insights into the patient’s sleeping behaviour. During this type of study, the patient will be required to stay overnight at the facility, so they should take everything needed for their usual sleeping routine, including pyjamas and toiletries.

How to prepare for a sleep study?

  1. Avoid coffee from the afternoon before the study.
  2. Avoid daytime naps.
  3. Arrive at the sleep lab early to allow for acclimatisation. Some people have difficulty sleeping in an unfamiliar environment, and this helps them fall asleep better. 
  4. Discuss concerns or worries you have about the sleep study with the technician available.
