Tri-Hospital Sleep Laboratory West

What will be done?
Bring your CPAP device along with your tubes, mask and headgear along with your health card, comfortable night clothes, toiletries and your usual medications. Leave all valuable belongings at home.

You will be set up for a sleep study with your own mask. When you sleep, you will be monitored for the quality of your sleep, oxygen levels, heart activity, body position and movements, breathing problems, awakenings and snoring. The airflow will be increased gradually until these events are normalized. The optimal pressure is determined and your machine may be adjusted in the morning or at the follow up visit with the sleep specialist.

Quality of Sleep
It is normal to encounter some discomfort the first time you use a CPAP machine and it may take a few weeks, sometimes longer, to get used to sleeping with a mask on your face.
There is no single mask that works the same for everyone, so finding the right mask for you may be a challenge, and takes time. Some masks are more suited to sleeping on the sides; others are better for less pressure on the face or persons with claustrophobia; and others are suite for persons with abnormal nasal passages requiring a full face mask.

You may be aware of more awakenings during the night and the quality of your sleep usually starts improving within a few nights. There will be more normal deep sleep as well as significant improvements in your energy, alertness, wakefulness in the morning, moods, concentration and memory. You may also experience pleasant dreams as compared to the distressing dreams you had before using CPAP while you were struggling to breathe in sleep.

The Future
Sleep apnea is closely associated with a number of serious diseases including heart problems such as hypertension, heart attacks, irregular heart rhythms; and brain problems such as strokes, memory loss, poor concentration, daytime sleepiness, and depression.

Regular use of the CPAP reduces these additional risks and their consequences, in the comfort of your bed. The benefits to your daytime activities, energy and wellness are immeasurable and irreproducible by any drug or known treatment. You can improve your health profile if your apnea is well treated. If you already have one of these conditions your chances of becoming disabled or dying early will be significantly reduced if your apnea is well treated.

Strengthening your breathing muscles with regular cardio exercises helps improve breathing during sleep, and reduces the resistance to airflow in the upper airways. As your energy level improves, so will your motivation to be more active and independent.

Please be aware that some masks lose their efficiency after a period of 6 months to one year, and may require replacement periodically.

Follow-up care
We will call you over the coming year to see if things are going well, and to help if they are not. If you do not hear from us at these times, please call us. In a busy office, unfortunately, people are sometimes missed. We do want to know how you are, and would appreciate a call from you.

Let us know if you notice a return of your symptoms, especially daytime sleepiness. Sleep apnea does tend to get worse over time as our body’s strength changes. New medications, weight gain, new illnesses, surgeries or just the passage of time can lead to a worsening of the apnea. If you notice changes, discuss them with your family doctor. The symptoms could be caused by many factors. If you family doctor thinks they might be from a worsening of your apnea, then a referral back to the Lab will be arranged and you can be tested again. A small change in your CPAP pressure may be all that is necessary. A significant weight loss may lead to your pressure level being too high. You may need to be retested and have a lower pressure prescribed.

If you experience significant discomfort, please consult your respiratory supply company. This laboratory is also available for advice if you continue to have any difficulty. We are here to help you

I know this machine will be of great help to you and that any discomfort it brings is far outweighed by the benefit it confers.
