Hospital Sleep Study Info

A sleep study (or polysomnogram) is a continuous recording of several types of measurements used to identify various sleep problems. These measurements involve attaching small metal cups (electrodes) with adhesive paste to the head to monitor sleep and its stages. Flexible bands are place around the chest and abdomen to measure breathing effort. Other sensors are placed on the legs, upper lip, neck, and finger to measure leg movements, airflow, snoring, and oxygen level respectively. None of these measurements hurt. The set-up is designed to be as comfortable as possible. The diagram below shows the position of the electrodes and sensors.

Will I be able to sleep in the Sleep Clinic?

This is one of the most common questions asked prior to a sleep study. Although the first night in a sleep clinic can be a strange experience with electrodes and wires attached to various parts of the body, most people do in fact sleep quite will. Sleep Clinic staff do their best to make the experience as comfortable as possible. You are encouraged to bring your favourite pillow, as the hospital issue pillows are covered with plastic, and some patients find their sleep disturbed.

To help ensure that you are able to sleep in the clinic, you are advised to follow this guide for the 5 nights leading up to your test:

• Nights 1-4: Sleep from 10:00 PM to 6:00 AM.
• Night 5: Sleep only 6-7 hours.

In the unusual event that you are unable to sleep long enough for us to properly ascertain clinical data, the study may have to be repeated. We will have night sedation available. If you suspect that you may have difficulty getting to sleep, please inform your tech that you would like night sedation.

What happens when I arrive at the sleep clinic?

After you have been admitted to the hospital, a sleep technician will meet you and show you to your room. The technician will explain the set-up and monitoring procedures to you. After changing into appropriate sleepwear, the technician will attach the electrodes and sensors, explaining the monitoring equipment as they go. This will take approximately one hour. Once set up, lights will be turned off about 10:00 PM and overnight monitoring will proceed.
