Aerophagia...CPAP vs. BiPAP

Post by sleep_quest » Sun Nov 23, 2014 7:51 pm

I'm still suffering with aerophagia and I'm wondering about the benefit of using a PRS1 760P to avoid the bloating. I've read that biflex/bipap can help with those issues, true?

I can only speak to my experience but with my strait cpap I can't get the pressure over 14 without having trouble. When I had a sleep study they raised the pressure to 19 14 on bipap and had no issues

I just switch to the machine you're talking about and I still have it. My Sleep Doctor recommended Gas X or equivalent. I tried that a couple of times. I feel much better in general with the quality of sleep I'm getting vs. my previous machine which was an Resmed S8 Autoset Vantage. But it was set 10 to 16 and my new machine is set for 12 with EPAP at 7 and Flex at 2. I go to bed early most days just in case there are sleeping issues but I get up about 6am most days to give myself enough time in the morning before I might have to leave. So, extra time sleeping and extra time in the morning being awake.

But yeah, no sign of aerophagia going away anytime soon. Maybe it's less so now that my pressure is slightly lower.

Switching to BiPAP helped me. I couldn't tolerate straight CPAP without severe aerophagia. After several years on BiPAP I began to have regular issues with aerophagia (8-10 nights a month) beginning last spring. It seems that my pressure needs had decreased a bit over time. It took time to figure out how low to go on the pressure, but once it was adjusted appropriately, the painful bloating went away again.

Even with BiPAP, excessive bloating would happen to me from time to time (less than once per month). With straight CPAP it happened every night. I keep Phasyme in my nightstand for nights when I wake up full of air. I haven't had any episodes at my new lower pressure setting, but I keep it in the drawer just in case.

If not for BiPAP, I would not have been successful with PAP therapy. For me it is worth the extra expense for the machine.

Good luck.

Note: horrible "gas pains" may be caused by a bad gall bladder, which can kill if ignored.
Please have that checked out.

Hmmm, so I guess it is hit or miss depending on whether it will help. Since I'm thinking about getting a 760 is there a general way of translating my current 560 pressures to the 760? I have a min of 8 and a max of 20 and I have hit 18 a few times. I don't have a user manual yet so I'm not sure how to set a 760 to refine the ipap/epap settings to avoid the bloating and gas. Any help is appreciated.

Thanks Chunky for the tip about the gall bladder. I've had trouble with mine in the past and this feels nothing like that did.

You can certainly start by reducing your max from 20 to 12 then monitor results.

You need to share the results of your titration for better advice.

Increasing from 11.5 to 12 made all the difference for me. .5 too much and I ended up in pain. Played with the settings until I could find a number that kept my AHI down without the aerophagia

One thing I tried but it didn't work. I raised the pressure to 16 with the epr set to 3.You would assume that with that setting it would be like have a bipap with a setting of 16 13 but out must not be because with the epr on 3 and the pressure at 16 I had bad blasting and pain

I would think there would be more exhalation relief with a BiPAP otherwise wouldn't any machine with Flex or EPR be the same thing as a BiPAP? And then they couldn't charge as much for the more sophisticated algorithm/software...

yes, a resmed set at 16 with three epr is a simple bilevel at 16/13

(bipap is a respironics trademark)

a bilevel allows more difference than EPR, epr only goes to 3, and bilevel can, if you for some reason needed it, be set 25/4 (depending on model)

if you've got your bilevel (bipap or vpap) machine set for a pressure support of 0-3, then it'll behave pretty much the same as a plain cpap with EPR.
