CPAP

What is CPAP?

CPAP stands for Continuous Positive Airway Pressure. They are medical devices which are important treatment options for people with OSA. There are now many different types of devices which work in a similar manner, depending on the manufacturer. CPAP devices usually consist of at least a mask, tubing and an air pump.

How does it work?

Think back to your childhood when you were blowing up balloons. You could blow the balloon up and change its size by either blowing in more or letting the balloon deflate into your mouth. The CPAP machines basically do the same thing but in reverse- you are now the balloon!

By forcing air into your nose or mouth when you are asleep, it generates an increased air pressure inside your throat and (hopefully) stops it from collapsing.

CPAP is considered the most effective non-surgical treatment for OSA. It is probably the most commonly prescribed first line therapy.

Is CPAP all I would need to do to treat my OSA?

It would be nice if the answer to this was "yes" but the truth is that CPAP is not a magic bullet. It is well known that compliance, or using it regularly, is not very good amongst patients. Below we talk about some things that people don't like about their CPAP.

As part of your treatment plan, it would be recommended that your diet and exercise levels be reviewed and adjusted, particularly if you are obese. The motivation and energy to engage in exercise is limited when you are not sleeping well, but with treatment such as CPAP, the good night's sleep that you get leaves you feeling refreshed and recharged.

Is it noisy? What will my partner think?

Hey you are already noisy. The CPAP machine will be like trading in the tractor for a small car.

If I have OSA, can I just buy a CPAP machine from the net? They look to be cheaper that way.

The machines do need to be purchased. Depending upon your health insurance status and fund policy, they may cover some of the costs involved. There are also Medicare safety net and potential tax rebates that apply to out of pocket health costs- you should talk to Medicare or your tax adviser about this.

As for the internet, these devices need to be professionally prescribed and fitted. You may find that you buy a device that does not suit you and end up paying again for the right device for you.

What are some common problems with CPAP?

It is not unusual for people to have problems with CPAP. You should not be put off though. The problems become less so as you get used to the device.

Here are some are some common CPAP device:

	The mask is uncomfortable. Just like hats come in different sizes so do the CPAP masks.
	My nose feels dry and blocked. You can try a humidifier or medications prescribed by your doctor. Some people benefit from nasal surgery, especially if you had nasal problems prior to using CPAP.
	I hate the mask and don't want to use it. There are alternatives such as jaw splints, sewing tennis balls in the back of your pyjamas and surgery.
