Diagnostic methods

How is Sleep Apnea Diagnosed?

Sleep Apnea diagnosis starts with completing a Sleep Apnea Screening Test, that includes clinically recognized surveys:

If you scored positive, or you think your loved ones may have a Sleep Apnea, you should talk to your doctor and discuss further investigation. If you require help in arranging a Sleep study, please Contact Us

Investigation may include referral for a Full Sleep Study-PSG (Polysomnography) conducted in accredited Sleep Disorder Clinics, or an easy to use In-Home Sleep Apnea Screening Study using portable monitoring device to provide a preliminary Sleep apnea diagnosis.

Full Sleep Study (PSG)

Polysomnography (PSG) is an overnight test covered under the OHIP, that involves a comprehensive recording of the bio-physiological changes occurring during the sleep.

Polysomnography (PSG) is a gold-standard test used to assess sleep quality, diagnose Sleep Apnea, and rule out other types of sleep disorders which may cause sleep disruption and negatively affect your health. PSG test is the most complete evaluation of your sleep that monitors and objectively measures:

  • Brain wave activity (EEG)
  • Eye movements (EOG)
  • Legs and Chin muscle activity (EMG)
  • Heart rate/rhythm (ECG)
  • Respiratory effort/Nasal Airflow
  • Blood oxygen levels (SpO2)
  • Body position
  • Snoring

A set of monitoring devices and electrodes will be safely attached using gentle adhesive/gel paste that is easily removed with soap and water in the morning. All sensors are applied only to the surface of the skin. The sleep test is non-invasive, easy and painless. The set-up process for the study takes about 30 minutes.

You will be given a set of questionnaires assessing your sleep habits and medical history. Patients are asked to go to bed around 10-11 P.M. and are usually released by 6-7 A.M. The whole visit to Sleep clinic is similar to spending night in a hotel and takes about 10 hours.

Your sleep study will be thoroughly analyzed by a physician specializing in Sleep Medicine. Based on the findings, the sleep doctor will provide you with specific recommendation and treatment options. A copy of the report will also be sent to your primary care physician.

In-Home Sleep Apnea Screening Study

In-Home Sleep Apnea Test may be considered if:

  • You want to have an immediate screening test for Sleep Apnea in the comfort of your home
  • Your physician wants to pre-screen for Sleep Apnea and determine the urgency for Full Sleep Study (PSG)

A simple and easy-to-use portable monitoring device will be provided to you by our Respiratory Therapist.

Portable monitoring will objectively measure:

  • Respiratory effort/Nasal Airflow (Breathing patterns)
  • Heart Rate and Blood Oxygen Saturation levels (SpO2)

The device is FDA approved and widely used around the world for Sleep Apnea screening.

Please keep in mind, In-Home Sleep Apnea Screening test has its limitations and does not substitute Full-Sleep Study (PSG) performed at Sleep Disorder Clinic.

The results of In-Home Sleep Apnea Test will provide preliminary diagnosis of Sleep Apnea and help your physician to determine if you are likely a candidate for an immediate Full Sleep Study (PSG) at Sleep Disorder Clinic.
