What is it?

CPAP stands for continuous positive airway pressure. It keeps your airway open as you sleep by providing you with a steady stream of air. Most CPAP units are about the size of a small tissue box. Today's units are smaller, lighter and quieter than when they were first used to treat sleep apnea. Some units are as small as six or seven inches in length and weigh only two or three pounds.

To power the unit, you simply plug it into the wall. The box has a fan that pushes air through a tube. The tube is connected to a mask that you wear as you sleep. The mask allows the air to gently blow into the back of your throat. This keeps the airway open and prevents pauses in breathing as you sleep. The mask must fit and make a seal in order to keep your throat open and correct the apnea problem. A good mask seal will prevent air leaks and maintain the proper level of air pressure.

The amount of air pressure needed is different for each person. A CPAP study during an overnight sleep study will show your sleep doctor the level that is right for you.

CPAP units come with a variety of features. Most units now have a pressure "ramp" setting. This timed setting starts the machine at a very low level of air pressure. It slowly raises the pressure until it reaches the right level.

Humidifiers are a common accessory for CPAP units. They provide cool or heated moisture to the air coming from the CPAP unit. This can reduce side effects and make it easier for you to breathe through your mask. Some CPAP units now come with an "integrated" humidifier that is connected to the machine.

New technology is making it easier for you to receive the maximum benefit from your CPAP therapy. Many CPAP units are now able to track your hourly usage and produce detailed data for your doctor. Some machines can also keep track of mask leaks and snoring. Depending on your model, you may be able to download this information to a computer or store it on a data card.

This information can help your doctor monitor your treatment progress without requiring you to make an office visit. Some units even allow your doctor to program your data card with changes to your air pressure level.

The types of CPAP that are available to you may vary. It can depend on your insurance coverage and also the region of the country where you live.

Some people with sleep apnea have other medical conditions that make their breathing problems more complicated. They may have lung, heart or brain problems. These people may need to have oxygen added to the air in their CPAP systems.

#1 Nasal Mask #2 Full Face Mask #3 Nasal Pillows
This mask only covers your nose and is the most common CPAP mask. This mask covers both your nose and your mouth. This type of mask may help if you have air leaks when using a nasal mask. This system uses soft silicone tubes that fit directly into your nostrils. It can also help eliminate air leaks and may provide you with a greater sense of freedom.

There are other types of masks that can be used in special cases.

No matter what type of mask you use, it is most important that it fits you well. The mask must make a seal and must be comfortable for you. First your health care provider will work with you to select the right size for your mask. The mask should fit snugly enough to prevent leaks without causing discomfort. You may need to make small adjustments to the mask, tubing, straps and headgear until you get the right fit.

Who gets it?

CPAP is the most common and effective treatment for obstructive sleep apnea. It may also be used to help people who have other breathing problems when they sleep.

Possible side effects?

The most common problem with CPAP is when the mask does not fit well. If the mask is too big, the straps holding it to your face will need to be pulled too tight. This can cause skin irritation or sores as the straps rub against your face. A mask that is too small will not seal properly and air will leak out through the edges. This can cause air leaks that blow into your eyes. Your CPAP supplier can help you make sure that your mask is a good fit.

CPAP may cause some people to have more nasal congestion. This can often be relieved with a saline nasal spray, a decongestant or a heated humidifier.

Using CPAP may also make your throat dry or sore. A heated humidifier that fits your CPAP unit can ease this symptom. Adding a chin strap may also help. Some people with this problem may need to change to a full face mask.

Other side effects from CPAP therapy are rare.
