Diagnosis of Sleep Aponea

The only way to confirm a diagnosis of sleep apnoea is with a polysomnogram or sleep study. This is used by the sleep physician to evaluate the extent your problem and help determine the most appropriate treatment. There are 2 types of sleep studies used.

In-lab overnight sleep study

This type of sleep study provides the most complete and reliable evaluation of your sleep. It requires you to stay overnight at a sleep centre, in a bed that in your own room. You will sleep with sensors hooked up to various parts of your body by a specially trained technician. These sensors record your brain waves, heartbeat, and breathing among other things.

In-lab overnight sleep study

Some patients with high risk factors for obstructive sleep apnoea and no other medical disorders may be appropriate for a home sleep test. This type of sleep study lets you sleep in the comfort of your own home while a machine collects information. The testing equipment differs in that it is less complicated than what is used in an overnight sleep study. A staff member will show you how to hook up the testing equipment yourself. Once you are finished, you can take the device back to the sleep centre or send it by mail.

There are a variety of home sleep testing devices that have different sensors and equipment. All home sleep test devices measure your breathing and blood oxygen level. Some may also measure your heart rate or other information about your body.

Home sleep testing may be recommended if:

  • It is highly likely that you have moderate to severe obstructive sleep apnea
  • You have no significant medical conditions other than the suspected obstructive sleep apnea

You should not have a home sleep test if:

  • You do not have a high risk of obstructive sleep apnoea
  • The physician suspects you may have another sleep disorder
  • You have certain medical conditions including pulmonary diseases, neuromuscular diseases or congestive heart failure

In these cases, an in-lab study may be recommended instead.
