Problems with CPAP and how to tackle them:

1. The wrong size or style CPAP mask

Work closely with us (booksleepstudy), your doctor and the CPAP supplier to make sure you have a CPAP mask that fits properly.

Try a different mask: Full face masks that cover your mouth and nose work well if you breathe through your mouth during sleep and also fit if you move a lot in your sleep.Another type of mask has nasal pillows that fit under your nose and straps that cover less of your face making it easier and less cumbersome.

Pay attention to size as there are different sizes available for various people.

2. Trouble getting used to wearing the CPAP device

Start with wearing the CPAP mask for short periods of time while you're awake and then during the daytime naps. Once you get used to the feel of the mask, start using it at night and persist with it for a couple of weeks tillit gets comfortable for you.

3. Difficulty tolerating forced air

This can be overcome by using a machine with a "ramp" feature which allows you to start with low air pressure. The machine then automatically and slowly increases the air pressure to your prescribed setting as you fall asleep. These days, all the new Auto CPAP machines already have an inbuilt system to adjust the pressure based on your sleep and snoring pattern.

4. Dry, stuffy nose and dry mouth

A leaky mask can cause dry nose. If you breathe through your mouth at night or sleep with your mouth open, some CPAP devices may worsen dry mouth. A CPAP device that features a heated humidifier, which attaches to the air pressure machine, can help. Using a nasal saline spray at bedtime also can help ease a dry, stuffy nose

5. Leaky mask, skin irritation or pressure sores

A leaky or an ill-fitting mask means you're not getting the full air pressure you need, and you may be irritating your skin. The mask can also blow air into your eyes, causing them to become dry or teary. Adjust the pads and straps to get a better fit. If you develop skin deterioration or sores, such as on your nose, tell your doctor promptly.

6. Unintentionally removing the CPAP device during the night

It's normal to sometimes wake up to find you've removed the mask in your sleep. If you move a lot in your sleep, you may find that a full face mask will stay on your face better.You may be pulling off the mask because your nose is congested. If so, ensuring a good mask fit and adding a CPAP-heated humidifier may help. A chin strap also may help keep the device on your face.

If this problem persists, consider setting an alarm for sometime in the night, to check whether the device is still on. You could progressively set the alarm for later in the night if you find you're keeping the device on longer.

7. Bothersome noise

Most new models of CPAP devices are almost silent. But if you find a device's noise is bothersome, first check to make sure the device air filter is clean and unblocked. Something in its way may worsen noise. If this doesn't help, have your doctor or CPAP supplier check the device to ensure it's working properly. If the device is working correctly and the noise still bothers you, try wearing earplugs or using a white noise sound machine to mask the noise. Placing the machine as far away from the bed as possible also may help make any machine noise less noticeable. Ask your doctor or CPAP supplier if extra tubing is available and right for your machine.

Time and patience are key to success
