What does this mean? My sleepy head data shows this and it can range from 8% on a good night to up to 37%. My AHI ranges from 0.8 to 12.9. I'm sleeping around 5/6 hours sometimes waking after 2 or three hours.

that you're having waxing and waning breathing. if you zoom in on the flow should see it.

it could mean you're venting excess co2, try turning down the flex setting.

Hi thanks, my cflex setting is on 1. Dreamstation. The periodic breathing has been as low as 8% and as high as 37% that was last night. I can see them on sleepy head and can last about 8 minutes each one. My pressure is min 12 and max 16. Had it like that for 8 days and the first 5 nights my AHI was never above 2, the best five days in a row. Then last two nights 10.2 and 13.9 mixed OAs CAs and hipopneas. Some advise to increase pressure but others advise to decrease. I spoke to a physio and he said to reduce it to 10- maybe 14 as pressure may be inducing the waxing and waning and the CAs. I had an ablation 6 weeks ago but otherwise no other heart issues, no heart failure etc. Any ideas? I'm new to this and getting confused.

the waxing and waning is *typically* a result of over/undershoot of co2 in the blood, the amount of co2 in the blood is what drives your natural desire to breath, if the co2 level is low, then you don't feel the need to breath. if you take a bunch of deep breaths, you blow off a lot of co2, then when you hold your breath, at first, you feel no desire to breath.... then it gets worse and worse. it's not a lack of oxygen, it's the co2 building up in your blood.

for a relatively small minority of people, their 'trigger' level is very sensitive, and the extra ventilation from a cpap cause cause them to go into a cycle like that, effectively inducing central apneas. the more ventilation, and more pressure, the worse the situation gets.

the flex setting increases ventilation encouraging you to breath deeper, and thus blow off more co2, which is why I suggested turning it down, or in your specific case, off.

Had pressure at 12-16 and c flex turned off. Felt like very high pressure and had slight sensation I couldn't get my breath. Woke after an hour, then another hour later and painfully bloated. 90% at 15 . AHI 4.8 and periodic breathing 38%. Had some hot milk and turned pressure down to 10-16 and slept ok for a further three hours. AHI 4.3 and periodic breathing down to 22%. Felt more rested. 14 OAs and only 4CAs and 7 hypopneas. Will stay at this for a few days. Any thoughts?

did you change anything besides the flex setting?

it'd help if you'd post some charts, following the examples in my sig.

I turned the cflex off, didn't change anything else, pressure at 12-16 but reduced at 03:00 am to 10-16 as just couldn't sleep and could hardly exhale. Took a while to feel ok but literally filled my belly. 10-16 felt much more comfortable. I'd thought cflex helped reduce periodic breathing and CAs as it's more like bipap?. I'm doing this from my iPhone and won't have wifi till Sunday. Will post 3/4 nights of data? I'm away on a retreat and if voyrse have my dreamstation with me ;-) iv got sleepyhead on my pic but no wifi ;-(
Thanks Gary

nope, the extra ventilation, while making it more comfortable and possibly helping with aerophagia, can, as explained, make centrals *worse*.

plain bilevel machines *DO NOT TREAT, or help* central apnea. it takes a ventilator to do that.

Thanks. There's so much to learn hey. Well last night was better. Pressure 10-16, 90% was 10. And AHI was 2.3. 1 OA, 5 CAs and 7 Hs. Periodic down to 10%. Slept 5.5 hours. I'm wearing a soft cervical collar as advised by someone on apnea board. But I'd also been advised there to keep increasing the pressure.

the answer to any obstructive events is almost always "more pressure".

But I'm understanding that more pressure in my case could be driving periodic breathing? But why was my OAs and PB also increasing with the pressure?

I haven't seen anything, I won't guess.

more pressure could be causing pressure induced centrals, more ventilation (cflex) can cause co2 imbalance over/undershoot centrals (periodic breathing). too little pressure allows the airway to collapse, causing obstructives.

I don't think I've ever seen more pressure cause more obstructives... it just doesn't work that way.... Jason?

hi, sorry ive not been able to access wifi for a few days and unable to upload via my mobile phone.
here goes. ill start with Thursday night. I started the night with pressure at 12 to 16 though it says 10. I had to turn it down as I just could not breathe. flex was off. I turned it down to 10. the rest of the nights are at 10 to 15 and alsthough the AHI was good, ive slept really badly, waking at about 2 hours then 4 and had to get up as unable to sleep and then back to bed for another hour or so. im wondering if there are leaks as I don't really understanbd the data. my dreamstation says 0 leaks but on sleepy head I can see different numbers

.http://imgur.com/a/a6Vrw

this was the night with 12 at the beginning and after I got up and returned to bed, eventually I turned it down to 10.

http://imgur.com/a/wBXOv. the following night.

http://imgur.com/a/Xo0DL

http://imgur.com/a/bgFuU


Im happy with the numbers but im not sleeping any better, even slightly worse. im hoping its just insomnia or anxiety rather than something wrong. im booked in for an oxygen test over night but not until the 13th of july. they seem rather unconcerned and say its fine.

id really appreciate some help with this. I am using the brevida mask and I don't wake to any leaks, that im aware of. today I received the nuance attatchement for the dreamwear. however im tempted to just stay with the brevida for now. im also excercising evey day with rapid walking for 45 mins and trying to lose weight, hoping that will help, at least with the obstructive apneas. re the periodic breathing, they said it was cheyne stokes, but did not explain anything. I read up on it and saw the link to heart failure, but I had an echocardiogram about 8 weeks ago and it was fine. I had a catheter ablation for atrial fibrillation 7 weeks ago and im on bisoprolol and an antigoagulant as well as an ace inhibitor. any avice or comments would be very much appreciated. im feeling rather alone with all this.
kind regards Gary

Please remove the charts that weren't requested, namely the useless AHI chart and the time at pressure chart, trying to scrunch all that on makes it pretty much useless. Please resize the other charts to fill the space.

it's looking a lot better with flex off, it might be that you just need some time to get more used to it.

Hi, yes perhaps, last night was 1.9 so that's now 6 nights under 5 and 5 in a row under 2. Last night, even though I woke after 3 hours I went back to sleep and woke to the alarm at 05:30, so a full 6 hours and feel quite rested. If I could get a consistent 6 hours sleep I'd be delighted. It certainly helps to get some feedback and encouragement. ;-) thank you.
Gary

some lucky people feel an immediate difference, many just gradually get better, like they gradually got bad.... though better usually happens faster than bad did... :D

one friend said she didn't think she was getting any benefit, until one day her dog got out and she chased him down the block... and then realized she'd ....been ABLE to chase the dog down the block, and not pass out... :D
