Ballooning caused by C-Pap machine?

I am wondering if the horrible ballooning at night, and the consequential blowouts, (horrible mess) are a result of the C-Pap machine, and swallowing air? Has anyone heard of this? Di

Absolutely! CPAP and BiPAP machines push air into the oral cavity, some goes into the lungs (as is the intention of the therapy) and some goes into the mouth (nothing you can do about this, it's inevitable).

Is the mask a nasal mask, or a full face mask that covers both the mouth and nose? A nasal mask that fits well would be the best option in reducing gas, and as well make sure you are followed closely in a sleep lab to make sure your pressures aren't any higher than need be for the desired result.

Higher pressures = more air going into your stomach = more gas. But, the most important thing is that you are getting enough pressure to reach a therapeutic level.

To explain just how much gas can be created (and explain the ballooning) with CPAP, some of our CPAP patients have GTubes (tubes that go into the stomach if they can't feed orally for one reason or another) and when they use their CPAP machines (at night or for daytime naps), they open their GTubes to allow the gas to vent out of their stomachs - so yes, good detective work on your part! If they didn't open their tubes to vent many get very distended and crampy stomachs.

The best suggestion I can give you is to maybe add an extra filter to the bag, like the osto-ez-vent. They will send you samples for free and your husband can quickly open the filter to let the gas out of his bags.
