2 Reasons Why Your Ears Pop During CPAP Use and What You Can Do About It

You settle in for the night with your CPAP mask on, but as you coast into the land of dreams, it happens—your ears start to pop. You feel like you’re taking off in an airplane. The sensation gets so bad that you can’t sleep and end up turning off your CPAP machine.

This phenomenon is certainly not unheard-of for sleep apnea patients. Here’s a few things that might be causing popping ears—and what you can do about them:

Swallowing Air
Known as “aerophagia,” this is when the air from your CPAP machine goes into your stomach instead of your lungs. Whenever you swallow, the pressure between your middle nose and ear become equal.

However, if you have an external change in pressure, this can cause your ears to pop if you swallow. Think about what it’s like when you swallow on an airplane or elevator—your ears pop. The same is true with a CPAP machine—you have external pressure, plus the change in internal pressure from swallowing. Those two things combined can cause your ears to pop.

So, what can I do?
Sometimes, all it takes is adjusting the pressure on your CPAP machine. Other times, you might want to try a different CPAP mask—or making sure the one you have fits you correctly. Chin straps can also help alleviate this affect.


Gastroesophageal Reflux Disease (GERD) keeps a band of muscles at the end of your throat from closing properly. This allows some stomach content to leak into your throat. Using CPAP can exacerbate GERD, especially if you have aerophagia on top of that. As the air enters the stomach, it can cause some of the stomach contents to come back up, causing your ears to pop.

So, what can I do?
Sleeping at an angle can help prevent some stomach contents to from coming back up. Eating light suppers or not eating several hours before bedtime is another fix. Wearing a full-faced CPAP mask can also cause you to swallow a lot of air, so switching to a nasal mask or pillow masks can help. Finally, switching from a CPAP machine to a BiPAP machine can address the issue of GERD.

    I’ve recently experienced the popping ear problem and I have GERD. My ENT doctor put tubes in my ears and it has lessened the occurrence of the airplane-like symptoms but not alleviated them completely. I use the nasal dreamwear mask. I’m also a Mouth breather and use a chin strap I’m a mess! and have my machine at 16. I’m in search of a new sleep doctor in the Richmond area as my present one said that CPAP couldn’t be the source of my ear problems!

    I have a new CPap machine ResMed AIRSENSE 10. I use a Wisp Nasal mask. Left ear popping drives me crazy. Can’t sleep. Really bad. I want to sleep. Should I consult an audio specialist?

    Left ear continues to pop so now I have ceased using my new ResMed AIRSENSE 10 machine. I have tried several things. Just tried Debrox earwax removal. Nothing changed. I am thinking of trying heating pad on my ear and face. I must get this eliminated. Thanks
