Anyone get a better AHI with AFLEX on 3? - tommydavid9343 - 08-03-2021 I understand that APAP is not for central sleep apnea, however, what I've noticed is I was going without flex for a while and it seemed I got used to it. I turned flex on 3 and it seems to make my body think its natural or something and I'm now getting scores of 1 or 2 which I never got before. For some reason it seems like it's helping my central sleep apnea go down. Why would this be? I know that Bipap can help with centrals and ASV. I hear people say it's only a comfort setting and nothing more on an APAP but for some reason it's giving me better results and I had no trouble breathing against the pressure with it off. RE: Anyone get a better AHI with AFLEX on 3? - ICEMAN - 08-03-2021 In generally I think should expect opposite, but may depends on Min & Max capability Auto pressure settings, as often see posted re more EPR gives more increases CA's, well at least to new users. As my thoughts then say auto pressure will compensate to a higher pressure on inhale so as to prevent any O or H ? at required level on Exhale? which then technically is actually increasing the overall pressure unless have capped the Max pressure? so that level EPR isn't capable to increase to that level? Others may be able correct my thinking's if incorrect! RE: Anyone get a better AHI with AFLEX on 3? - tommydavid9343 - 08-03-2021 Well, I am fairly new to APAP so I don't know a lot about it but I've had it over a month and I've kinda studied what makes my AHI better or worse. I have it set at 10-20. For a long time it would hover around 15 while I was asleep. Lately it has been hovering around 11.5 or so. I seen someone in a YouTube video address Co2 and how it can cause some to have central sleep apnea if it doesn't escape the mask fast enough on higher pressures. I have a ResMed AirFit F20 and the air that comes out of it isn't a lot at once. I have other mask and those release a lot of air but this one, you can barely feel the air coming out of it. It is dispersed around the sides through a filter because it has the Quiet Elbow. RE: Anyone get a better AHI with AFLEX on 3? - ICEMAN - 08-03-2021 Best to put up screen shot so as to allow analyise, and such as 90-95% and TYPE of events, pressure graph, EPR, leaks, CA & positional events etc. Is bet to Set up your OSCAR chart's as per: http://www.apneaboard.com/wiki/index.php?title=OSCAR_Chart_Organization May not be able post Screen Shot ! I think may be limit on how may need post 1st before, screenshot? but just shout out, I think someone will fix you up? They will probably tell if have CA's why have EPR on 3 and to reduce it ? but then what events having if clustered H or O may, say its sign of chin tucked in say from to big pillow under head need Supine position and also need flatten pillow otherwise if in such as fetal position and have chin tucked in, either way position a Collar may help with those position Event's? But then in reality, i am just stabbing in the dark, most common things, also may be just CAPA beginners, emergent central sleep apnea, until hopefully adapt adjust to machine, so really do need a picture, and some the experienced knowledge's will chime in and assist out. You did say that did say, hovering around 15 and lately 11.5 but then is that pressure or AHI ??? Now re Co2 that from my understand is CA is from generally re CO2 low levels, so is not triggering then to breathe out or for more O2 in as only have low CO2, and don't quote me others will explain better, than I have worded it but if if wrong someone will chime in and correct it. You also said I'm now getting scores of 1 or 2 is that AHI ? and never got before. so why didn't stick with those setting, was not broken ? Note EPR is just a comfort setting, think more so for High pressure assist against exhale if needed? also better put in, may use in assist Large leaks also against higher pressure to that also ? as have read some saying similar to that I think ?

While higher pressures can result in the appearance of central apneas in a few, I'm not sure of the mechanism. Higher pressure fluctuations, possibly occurring with the higher pressures, will cause increased flushing of CO2. Not escaping 'Fast Enough' means that your CO2 levels would be higher thus tending to prevent central apneas, not cause them. Time will normally yield fewer central apneas simply as your body adjusts to its new lower level of CO2.

Things change as you adapt. With flex set to 3 you have a lower exhale pressure plus the way the pressure changes as you transition from inhalation to exhalation changes. It is designed to make you more comfortable and make breathing more natural. It could be that it's helping you adapt. Quote:For some reason it seems like it's helping my central sleep apnea go down. Seems? Can't you look at the data and tell for sure? |
