Our Sleep Disorders Lab is dedicated to diagnosing and treating patients with sleep-related disorders. These conditions include difficulties falling asleep and / or staying asleep at night, or difficulty in staying awake during the day. Sleep apnea is a condition that is known as momentary cessation of breathing while sleeping and it is one of the most common disorders. It can interrupt sleep hundreds of times a night and can potentially be fatal.

  • Symptoms of potential sleep disorders include:
  • Constant drowsiness
  • Irritability
  • Loud or irregular snoring
  • Difficulty breathing during sleep
  • Morning headache, sore throat or mouth dryness
  • Loss of energy, excessive fatigue
  • Frequent awakening

Services at the Apnea Health Laboratories are provided by professionals experienced in sleep-related disorders and sleep-exacerbating diseases.

Our laboratory has combined 2 private rooms, one for each person being tested. We provide a single bed with all the linen. The rooms are quiet, darkened and air-conditioned. We also have a washroom and a shower.

As part of your sleep evaluation at Apnea Health, you will be asked to complete a sleep disorders questionnaire prior to your arrival at the sleep lab. This will provide us with more information about your sleep problem(s) and usual sleep patterns so that we can better serve you.

When the patient arrives they are shown where they will sleep and asked to change into their sleepwear. Then they will have physiological sensors connected to their bodies by the technologist assigned to them. These are all non-painful and comfortable enough so that it will be possible to sleep.

We use scalp electrodes, facial electrodes, chest electrodes, leg electrodes and a nasal airflow sensor. The polysomnography technologist applying the electrodes will be happy to answer any questions the patient may have. When the connections are complete, the patient is asked to lie down in their bed. At this time we check to see that all the sensors are working properly by having the patient perform some movements such as blinking, moving of legs, taking a deep breath, etc. Patients are permitted to sleep as they would at home, i.e. rolling over, personal pillows, bathroom breaks etc.

A technologist is ALWAYS present and able to provide assistance at any time (i.e. washroom). The overnight test lasts approximately 7 hours. Note: the technologist may, on occasion, enter the room to make some technical adjustments but we try to interfere as little as possible. We would like patients to enjoy uninterrupted sleep as much as possible.

The study is interpreted following the overnight sleep session first by a technologist then by the respirologist.
