What is a sleep study and why am I having one?

The sleep study is called a polysomnogram (PSG) and it’s a safe, painless, and simple evaluation of how your body functions during sleep. It is performed by a registered sleep technician. Data is recorded while you are sleeping and later reviewed by a board-certified sleep physician.

The study can provide a detailed evaluation to determine if you have a sleep disorder. If you do have a sleep disorder, it is important to be diagnosed and treated. Untreated sleep disorders can contribute to other diseases and conditions such as; stoke, heart attack, high blood pressure, and depression.

A common sleep breathing disorder, Obstructive Sleep Apnea(OSA), is caused by the airway closing and preventing the flow of air into the lungs. The resulting pauses in breathing can occur 30 times or more per hour. Without effective treatment, people with OSA may be at risk of developing a number of serious health concerns. Because of the excessive daytime sleepiness that exists with OSA, drivers who are untreated can become a hazard to themselves and others while on the road.

Where are sleep studies held?
Sleep studies can occur in our clinic, called a sleep centre or in a sleep lab. These facilities have staff and equipment dedicated to diagnosing your sleep disorders.

How long will it take?
The visit to the sleep centre takes a total of about 10 hours. The set-up process for the study takes about 30 minutes.

What kind of room will I be sleeping in?
For your comfort and privacy, the sleep lab is designed just like a bedroom. There is a bed with pillows and blankets. There may be a nightstand and reading lamp in the room. You can bring objects from home to make the environment more comfortable for you, if you wish.

What do I need to know or do before my sleep study?
One week before your study: You may be asked to keep a list of your sleep habits. This will provide your physician and the sleep lab staff with important backgrounds and information on your sleep habits. Also include a list of any medications you are taking and note your use of caffeine, alcohol, or drugs may be requested.
The day of your study: Shower, shampoo and dry your hair.Please arrive at least 15 minutes early for your study. Leave your non-essential valuables at home.  Bring your two-piece comfortable sleep attire and slippers.
What not to do the day of your study: Don’t nap, use hair gels, creams, oils, hairspray, lotions, or creams on your face or body. Don’t wear makeup, jewelry, acrylic nails, or hair braids/weaves. Don’t consume caffeinated foods or beverages (avoid chocolate, coffee, tea, soda, etc.)

What happens during the study?
When you arrive for your study you will be greeted by a staff member who will show you to your room and provide an explanation of the sleep study process. There may be a questionnaire for you to fill out. Then you will change into your sleep attire.
The sleep technician will attach sensors to part of your body such as your scalp, forehead, chin, chest, ankle/leg and index finger. These sensors measure the activities of your brain, heart, lungs, and certain muscles as you sleep. The sensors are painless and are attached using a temporary adhesive/ gel paste that is easily removed with soap and water. Unless your body hair is extremely thick on your legs or chest, you will not be required to shave. Elastic bands may also be placed around your chest and abdomen to measure your breathing.
The sensors are connected by wires to a computer that records and stores data. The wires are small and long enough for you to to move around in bed. After the wires sensors are applied you can watch television, read a book, or simply lie in bed until you are ready to fall asleep.
If you need to use the restroom during night the sleep technician will discuss this procedure with you.
The sleep technician will be situated at a separate work station which has various monitoring and recording devices which provide a full evaluation and report. If the technician becomes aware – from the data being collected and monitored – that you may have a severe sleep breathing disorder and may benefit from immediate therapy that involves airflow to your airway, they will awaken you to apply the therapy equipment. Once you fall back to sleep, data will be collected on how you sleep patterns respond to the therapy. How long it takes you to fall asleep is a part of the data that will be recorded.

What happens in the morning?
Your study will end when the technician determines that sufficient data has been recorded or when you awake in the morning. You will be able to work the next day if needed and will be out of the sleep clinic between 6-7 am.

How long will it take to get my results?
On average, results take approximately two weeks and will be sent to your physician, who prescribed the study. Your doctor will contact you to review the results, discuss if a diagnosis has been made, and determine if therapy is needed.
