CPAP is an important treatment for obstructive sleep apnea, but may be frustrating at first. Learn how to avoid uncomfortable masks and other common CPAP problems.
Continuous positive airway pressure (CPAP) therapy is a common treatment for obstructive sleep apnea. A CPAP machine uses a hose and mask or nosepiece to deliver constant and steady air pressure.
Common problems with CPAP include a leaky mask, trouble falling asleep, stuffy nose and a dry mouth.
The good news is that if one CPAP mask or device doesn't work for you, you have other options. And most CPAP masks are adjustable, to help make them more comfortable for you.
1. The wrong size or style CPAP mask
Work closely with your doctor and CPAP supplier to make sure you have a CPAP mask that fits properly. Everyone has different face shapes, so the right style and size mask for someone else may not work for you.
- Try a different mask. A range of CPAP masks are available. For example, some feature full face masks that cover your mouth and nose, with straps that stretch across your forehead and cheeks. These may make some people feel claustrophobic, but they work well if you prefer to breathe through your mouth during sleep. They also provide a stable fit if you move around a lot in your sleep.
Other masks feature nasal pillows that fit under your nose and straps that cover less of your face. These can feel less cumbersome.
Nasal pillows may work well if you wear glasses or read with the mask on, because some don't block your eyes as much as full face masks do. However, this may not be an option if you move around a lot in your sleep or sleep on your side.
- Pay attention to size. Most masks come in different sizes. Just because you're a certain size in one mask doesn't mean you'll be the same size in another. CPAP masks are usually adjustable.
Ask your doctor or CPAP supplier to show you how to adjust your mask to get the best fit. Manufacturer product instructions also can help show you how to do this. A properly fitting mask shouldn’t be uncomfortable or cause pain.
2. Trouble getting used to wearing the CPAP device
First, try wearing just the CPAP mask for short periods of time while you're awake — for example, while watching TV. Then try wearing the mask and hose with the device turned on during the day while you're awake.
Once you get used to how that feels, start using the CPAP device every time you sleep — including naps. Just wearing the CPAP device every now and then may delay getting used to it. Stick with it for several weeks or more to see if your mask and pressure are right for you.
3. Difficulty tolerating forced air
You may be able to overcome this by using a machine with a "ramp" feature. This setting 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. Your doctor can adjust its rate.
If this feature doesn't help, talk with your doctor about changing to a device that automatically and constantly adjusts the pressure while you're sleeping. An example is a bi-level positive airway pressure (BPAP) machine that delivers more pressure when you breathe in (inhale) and less when you breathe out (exhale).
4. Dry, stuffy nose
Check to make sure your mask fits well. A leaky mask can dry out your nose. If you have to tighten straps often to prevent air leakage, the mask does not fit properly.
A CPAP device that features a heated humidifier, which attaches to the air pressure machine, can help. You can adjust the level of humidification. Using a nasal saline spray at bedtime also can help ease a dry, stuffy nose.
5. Feeling claustrophobic
Practice using your mask while you're awake. First, just hold it up to your face without any of the other parts. Once you're comfortable with that, try wearing the mask with the straps.
Next, try holding the mask with the attached hose on your face, without using the straps. Turn on the CPAP machine, perhaps with the ramp feature turned on. Next, do this using the straps too. Finally, try sleeping with the mask and machine on.
Relaxation exercises, such as progressive muscle relaxation, may help reduce anxiety related to CPAP use.
If you're still feeling claustrophobic, talk to your doctor or CPAP supplier. It may help to get a different size mask or try a different style, such as one that uses nasal pillows.
6. 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.
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 has changed a lot. Or try a different style device such as a nasal pillow. If you develop skin deterioration or sores, such as on your nose, tell your doctor promptly.
7. Difficulty falling asleep
Wearing the mask alone for some time during the day may help you get used to how it feels and make it easier to fall asleep at night.
Machines with the ramp feature that slowly and gradually increase the air pressure to your prescribed pressure setting as you fall asleep may make you more comfortable at bedtime.
Following good general sleep habits also are helpful. Exercise regularly and avoid caffeine and alcohol before bedtime. Try to relax. For example, take a warm bath before you go to bed. Don't go 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. 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. Ask your doctor or CPAP supplier how to properly clean your mask and hose.
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
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 complications of obstructive sleep apnea, such as heart problems and excessive daytime sleepiness.
Work with your doctor and CPAP supplier to ensure the best fit and device for you. Regular visits to your sleep doctor are important and can help troubleshoot any problems and adjust settings, if needed. It can take a while to find the correct settings and get used to the mask.
With time and patience, CPAP can positively affect your quality of life and health. If you need help finding the right CPAP mask, or replacing your accessories, call Alaska Sleep Clinic today or order online, right here at www.AlaskaSleep.com.
