swallowing air?

what do you do to avoid it and fix it?

thanks

A forum search on Aerophagia should help - lots of info!

What are your pressure settings?

Consider having your doctor lower your pressure. That worked for me.

Here's a starting point in reading.
wiki/index.php/Aerophagia

You are already on probably the best machine to try to reduce the symptoms using pressure adjustments. If it's real bad you may have to do some tweaking with the pressures to see if you can find a spot where the discomfort is tolerable or gone and not let too many apnea events slip past the defenses.

Like some people might find that as long as the machine doesn't go over say (for example) 12...they keep the aerophagia monster away well enough and the AHI is still acceptable.
Don't know where your line might be...that's something you have to figure out.

How bad is it? Just annoying or making you physically ill?

It happened at about 12:30 AM; I sat up for about an hour before I felt comfortable enough to go back to sleep. Moleskin and 2 chinstraps. I woke up so much earlier than usual because that air swallowing did a number on me. It still hurts 18 hours later but not nearly as bad. It's never happened like this before. I'll check your links. I would have done that at the outside if this hadn't been so bad.

Tuesday night I turned it up to 11 (from 10.2) to see what would happen. It blew my face off. When I went back to bed at 1:30, I turned the MIN EPAP down to 10.6.

Min EPAP 11 - Max 14 until 12:30
Min EPAP 10.6 beginning at 1:30, max was 14 all night long
PS 6-12 the whole night
ramp 15 min, start EPAP 4.0

Monday night, airfit F20, laid some moleskin around my nose and at the bridge, and used two chin straps instead of one with settings of:
Min EPAP 10.2 - Max 14
PS 6 - 12.
ramp 15 min, start EPAP 4.0

The waking up at about 11:30 on both nights was due to my becoming extremely cold. So much so that I had to warm up with a blow-dryer. That happens most nights and can't be helped. My body temp is always low. It's too cold to sleep without a comforter, even in the summer, and with one I start to sweat and then, an hour or two later, I start freezing. On my back is the only way I can sleep.

thanks

I fart, I fart a lot.

What machine are you using?
Your profile says AirCurve 10 VAuto but the graphs look ASV to me and your PS min and max...that's an ASV setting.
I didn't think the VAuto had anything but fixed PS.
How come you cut off the useful stuff on the left side of those graphs?

It's a balancing act, getting enough pressure to kill the events but not too much that you get intolerable aerophagia. You need to keep tweaking the minimum and maximum until you achieve that balance, and it may be that you have to be content with a slightly higher AHI than you'd ideally want to compromise getting quality of sleep. My aerophagia is tolerable and my AHI varies between 0.6 and 3.6, the lower AHI is always accompanied by more gas, and I assume it's also when I sleep more on my side.

1) I left out the left sidebar because I screwed up, again. here are the corrected screenshots:

2) The outside of the machine at the bottom and immediately left of the humidifier says "AirCurve 10 ASV"

3) I entered the VAuto machine on my profile because my doctor wrote 4 settings on his Rx.

and "AirCurve 10 S" appears nowhere on my machine.

I assumed that that meant I should select ASVAuto as my machine.

4) Only in ASVAuto mode are there 4 settings, Min/Max EPAP & Min/Max PS. ASV mode does not have values for Min EPAP & Max EPAP. It has only an "EPAP" setting and the Min/Max PS settings

I was physically ill. I didn't try to go back to bed for an hour
thanks - a lot - for bearing with me

I don't think that your particular model AirCurve 10 is available in the profile equipment menu because cpap.com doesn't sell it and all choices are tied to items cpap.com either currently sells or has in the past.

In your situation you probably should just manually write it in in the comments section
"AirCurve 10 ASV"
The AirCurve 10 Vauto is not the same machine.

Are you using this machine for treatment of central apneas? If so I wouldn't go making any changes without consulting your doctor because limiting IPAP or EPAP without knowing what you are doing to seriously impact the central apnea treatment.
If your swallowing air symptoms persist and are significant...talk to your doctor about them if your diagnosis was either complex sleep apnea or central apnea.
When you go messing with the settings you could inadvertently tie its little hands so that it can't treat the centrals. We sure don't want to do that.

Your PS minimum of 6 is by default greatly increasing the IPAP. EPAP plus PS equals IPAP.
So your IPAP is significantly higher right from the onset. If you were to reduce PS that would reduce IPAP (which is probably the biggest factor in your aeraphagia issues) and as long as you didn't reduce PS max the machine could still treat the centrals with PS if needed.
PS could maybe be reduced to 3 or 4 and with no other changes at all it might allow for IPAP to be enough to deal with centrals as long as PS max isn't changed.
EPAP minimum could also maybe be reduced a little as long as the hyponeas and OAs didn't start happening.

Now if you don't have any central apnea at all and you are using the ASV just because you want to and no doctor is involved then we could maybe do some tweaking and help the aerophagia but if you are under a doctors care for central apnea when it probably would be advisable to alert him to the situation if the aerophagia persists.

but, you didn't, you put the wrong machine in your profile.

profile wrote:Machine: AirCurve™ 10 VAuto BiLevel Machine with HumidAir™ Heated Humidifier

the VAuto is not the ASV.

if there's not a correct matching entry in the profile list, then don't select anything, and put the machine in as a comment, like mine is.

Funny and accurate. Me too.
Although since switching to ACAP I have noticed a huge improvement as my 90% pressure is 17 as opposed to the fixed 19 I ran at for 7 years.
