1. How common is Obstructive Sleep Apnea (OSA)?

According to the Canadian Lung Association, OSA affects 4% of adult men and 2% of adult women. OSA can affect children as well, usually those with enlarged tonsils. OSA also shows a familial tendency.

2. What causes the airway to collapse during sleep?

• Extra tissue in the back of the airway such as large tonsils
• Decrease in the tone of the muscles holding the airway open
• The tongue falling back and closing off the airway

3. How long does it take to get used to CPAP?

Generally, clients can adjust to CPAP in 1-2 weeks. Occasionally, it may take a little longer if, for example, you are very sensitive to the feel of the mask on your face. **All masks are latex free.

4. How quickly after starting CPAP therapy will I feel less tired?

It generally varies from person to person; some feel immediate improvements, others take a while longer. It is also dependent on your OSA severity level – those with more severe OSA tend to notice a quicker improvement.

5. Do I need to use CPAP every night?

As there is no known cure for OSA, it is very important to continue with your prescribed therapy. CPAP therapy will 100% effectively control sleep apnea as long as you continue to use it.

6. What if I travel overseas?

CPAP units are portable and you should take it with you. CPAP units have an internal converter, making it very easy to travel overseas as long as you have the correct plug adapter for the country you are travelling to.

• Please Note: Your CPAP unit should be a carry-on item for airplane travel.
• If you are camping, special adapters can be ordered; contact the RT in your area for more information.
• Humidifier chamber should always be completely dry before moving your CPAP machine or readying it for travel.

7. What problems can occur while I am using CPAP?

• Nasal stuffiness, congestion, or dryness
• Dry mouth
• Mask air leaks
• Sore, dry or red eyes
• Skin irritation from the mask and/or air
• Sensation of too much air in the chest
• Sensation of abdominal bloating, cramping or gas
• Persistent sleepiness despite regular use of CPAP
• Feeling claustrophobic with the mask
• Waking up having taken the mask off

These problems should be addressed with your RT and/or physician and suggestions will be made to alleviate any issues/discomfort.

8. How will I know if my CPAP pressures need adjusting?

You will need a CPAP titration (adjustment to pressure) if:

• you have recurrence of your sleep apnea symptoms – excessive daytime somnolence, snoring, unrefreshing sleep
• you have significant weight gain or loss

9. If I lose weight, can I stop using my CPAP?

In general, weight loss may improve the severity of your sleep apnea, but does not necessarily cure the sleep apnea. However, it is possible that significant weight loss (more than 10% of your body weight) can mean the pressure settings could be lowered.

10. Will my blood pressure improve after I start CPAP?

Sometimes, but do not alter your current medications; always consult your doctor.

11. Will I ever be able to stop using CPAP? Will I ever be cured of my snoring and sleep apnea?

Unfortunately, OSA is a long-term condition with no known cure at this time. However, CPAP therapy is the most 100% effective therapy to control sleep apnea as long as you continue to use it.
