CPAP machines: Tips for avoiding 10 common problems
6. Leaky mask, skin irritation or pressure sores
A leaky or ill-fitting mask means you're not getting the full air pressure you need, and you may be irritating your skin. It can also release air into your eyes, causing them to become dry or teary. Try adjusting pads and straps to get a better fit. If the device fits over your nose, make sure it doesn't sit too high on the bridge of your nose, which can direct air into your eyes.
You may need to ask your supplier to help you find a different size mask, particularly if your weight changes markedly, or try a different style device, such as a nasal pillow or a mask with an inflatable cushion that contours to your face. If you develop skin deterioration or sores, such as on your nose, tell your doctor promptly.
7. Difficulty falling asleep
This is a normal, temporary problem. Wearing the mask alone for some time during the day may help you get accustomed to how it feels. Using the ramp feature, which provides an automatic, gradual increase in the air pressure to your prescribed pressure setting as you fall asleep, also may help. And practice good general sleep habits — exercise regularly, avoid caffeine and alcohol before bedtime, and try to relax. For example, take a warm bath before you go to bed. Avoid going to bed until you're tired.
8. Dry mouth
If you breathe through your mouth at night or sleep with your mouth open, some CPAP devices may worsen dry mouth. A chin strap may help keep your mouth closed and reduce the air leak if you wear a nasal mask. A full-face-mask-style device that covers your mouth and nose also may work well for you. A CPAP-heated humidifier that attaches to the air pressure machine also may help.
9. 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 is a consistent problem, 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.
10. Annoyed by the 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 be contributing to 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.
Time and patience key to success
Using a CPAP device can be frustrating as you try to get used to it, but it's important you stick with it. The treatment is essential to avoiding obstructive sleep apnea-related complications, such as heart problems and daytime fatigue. Work with your doctor and CPAP supplier to ensure the best fit and device for you, and try making adjustments if you're experiencing some of the common CPAP problems. It may take several months to find the correct settings for you and to adapt to the mask. With time and patience, CPAP can positively affect your quality of life and health.Previous page
