What is Continuous Positive Airway Pressure?

Continuous Positive Airway Pressure (CPAP) is a common and very effective treatment for obstructive sleep apnoea. CPAP treats sleep apnoea by providing a gentle flow of positive air pressure through a mask which splints the airways open during sleep.

How does it work?

When CPAP is applied, air is pumped through a mask into your upper airway acting as a splint to hold your airway open so that you can breathe normally. This prevents the upper airway from collapsing and thus prevents apnoeic events and snoring.

CPAP masks come in all shapes and sizes, just like every individual’s personal preference. However, there are typically four different variations of sleep apnea masks to choose from: nasal pillow, nasal, full face CPAP masks, and oral masks. Finding the right sleep apnea mask for your own level of comfort is essential in successful CPAP therapy.

How can it help?

When used properly, CPAP can alleviate the following symptoms caused by sleep apnoea:

CPAP - Obstructed airway during sleep

Obstructed airway during sleep

  • Daytime Sleepiness

  • Fatigue

  • Morning headaches

  • Poor concentration or memory

  • Decreased libido or impotence

  • Decreased attention

  • Depression

  • Decreased dexterity

  • Personality changes

In some people these changes will occur after the first few nights of CPAP, in others it may take several weeks or even months to get the maximum effects.

Is CPAP a cure for OSA and snoring?

CPAP controls OSA while it is being used however the causes of apnoea are still present. if you stop using CPAP, the sleep apnoea will recur. If there is any snoring while on nasal CPAP, there is a problem with the pressure.

What happens in the Trial?

The initial appointment will take approximately 1.5 hours. At this appointment you will trial a number of different masks to find the one that best suits your needs. You will also be shown how to use the CPAP machine.

You will be provided with a mask and machine to take home with you to trial for a period of four weeks. Over the course of the next four weeks you will have three subsequent visits where well-trained staff will monitor your progress, troubleshoot any problems that you may encounter and address any concerns you may have; all to ensure that you receive optimal treatment.

What happens after my four week trial?

At the end of the trial, we will have determined the best course of action for your treatment. The sleep consultant will then make a recommendation as to your CPAP needs; giving you a choice as to whether you purchase, continue to rent or explore other treatment options…

Follow-up with your referring doctor

You should make a follow up appointment with your referring doctor at the end of the four weeks to discuss the results of your trial.

How often should I get a check-up?

Once on CPAP you should return every 6 months to get your mask and machine serviced and to ensure that your treatment is still working effectively.

It is recommended that a review sleep study be conducted once every 12 months and more often if you have lost or gained a significant amount of weight.

Yearly home sleep studies are covered by Medicare.
