This is a test carried out to determine how restricted your breathing is when you sleep. It also indicates the degree to which this restriction causes droppage in oxygen levels. There are four levels of sleep test available. Each has a differing amount of information it is able to provide. For example, an in-lab test gives detailed and complex information about your breathing and how your body responds. A home sleep test picks up oxygen levels and heart rate. All of the tests occur at night time and aim to recreate your normal sleeping pattern.
The tests have been used safely for many decades, and thousands are carried out in a week across Australasia alone.
In the context of Sleep Surgery, the sleep study is used to direct initial treatment and also to check the degree of improvement after surgery.
