Pediatric Polysomnography examination

Polysomnography is another diagnostic tool for pediatric clients. Similar to the test used for adults, it captures physiological data from your child.

Examination procedure

The procedure is the same for both children and adults. The main difference is the arrival time, which can be arranged according to your child’s regular routine. To properly prepare for the test, your child should avoid consuming soft drinks or other foods high in sugar a few hours before the test. Please note that you will not be able to sleep in the same bed as your child so as not to interfere with the results. However, a second room will be provided so that you can spend the night with your child.

  • When you arrive at Biron's clinic, a healthcare professional will welcome you, show you and your child your private bedroom (with bathroom) and explain the examination procedure. The bedroom will be dark and quiet so your child can relax and fall asleep. It is equipped with an audiovisual system for diagnostic purposes and to ensure your child's safety. Their sleep will be observed throughout the night by a healthcare professional trained in sleep care, who will monitor proper recording of the data as well as your wellbeing at all times.

  • Before bed time, several sensors will be applied to your child's scalp, temples, hands, chest and legs. These record:

    • Electrical brain activity
    • Eye movements
    • Muscle tone
    • Heart rate
    • Breathing movements
    • Blood oxygen level
    • Body position
    • Limb movements
    • Snoring

To put your child at ease and improve the chances of a restful night, remember to bring his or her pyjamas, slippers, favourite toy or any other items commonly associated with bedtime.

If your child is ill on the day of the test (cough, fever, vomiting, etc.), we invite you to contact our Service Centre to assess whether your child’s appointment should be rescheduled.


Your examination results will be interpreted by one of our medical specialists trained in sleep care.

Depending on the method you choose either through the result portal or by post office, your test results will be sent to you and the requesting health care professional within 10 to 15 business days.

A medical prescription is required to perform this examination.
