Sleep studies

A sleep study is a test that is done to diagnose your child's sleep problem. A sleep study is an overnight test that monitors brain waves, breathing through the nose and mouth, oxygen and carbon dioxide levels, heart rate and body movements.

When you arrive, the Sleep Unit staff will explain what will happen, but generally, the following procedure occurs.

  • Sensors are attached to your child's head, chin, face, chest and legs. This is painless.
  • Your child is then free to move around, eat dinner, watch television and play until bedtime.
  • Before your child goes to bed, a small plastic tube is put under the nose to measure airflow.
  • Two elastic straps are put around the chest and stomach to measure breathing.
  • A probe is put on the finger to measure oxygen.
  • Another sensor is put on the skin to measure carbon dioxide and another plastic sensor above the top lip to measure breathing through the mouth.
  • All the sensors are then connected to a computer which monitors the study.

A parent is required to stay overnight with their child. A bed is provided for only one parent.

We hope to monitor your child for at least eight hours overnight. We will wake your child between 5:30 am and 6:00 am and disconnected from the sensors. Your child can then shower and then you are free to go home.

The results of the sleep study will be sent to your referring doctor.

What do you need to bring?

Dinner is provided for your child. If your child is bottle-fed or has special diet needs, please bring these with you. The Sleep Unit has a fridge and microwave.
The cafeteria is also open until 8pm where you can purchase meals.
