New Guy, Central Sleep Apnea, wrong machine?
#71
RE: New Guy, Central Sleep Apnea, wrong machine?
Having the asv on when you are awake, will cause it to go crazy. The awake breathing pattern is too irregular. Have a look at your awake and asleep tidal volume chart, to see the difference.
The first thing is to have the machine set, so you can keep the mask on all night. Then go from there. It depends how compliant your lung is, to how much pressure it needs to inflate. The machine will work it out. Your new setting of max ps:10 may well be enough for now. A young healthy 20 year old would need less, than a copd smoking 60 year old.

also, as sleeprider said, diet can also help, if you have any indigestion. google: LCHF gerd.

For auto-cpap, from machine data or software. You can set the min pressure 1 or 2cm below 95%. Or clinicians commonly use the maximum or 95% pressure for fixed pressure CPAP, this can also be used for min pressure.

That makes sense, I'm looking at the tidal volume and it is absolutely different, Like around average 600 sleeping vs 1800~ while awake.   That's 'the amount of air displaced',  is that the transfer of air from inhale to exhale and vice versa? Volume Measurement? and is that with the machine or is that just on my own?  .

"Tidal volume (symbol VT or TV) is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied. In a healthy, young human adult, tidal volume is approximately 500 mL per inspiration or 7 mL/kg of body mass."

It was mentioned to compare the Tidal Volume and Minute Vent. data vs getting an o2 meter. I'd prefer to not have to get another meter, but I'd like to make sure I'm looking at all this data correctly. It does seem that most of my settings are doin me right.

Minute volume then is the amount inhaled or exhaled in a minute. Hope you're starting to feel a bit better BTW. And yet another Happy New Year's wish.

Sleep-well

RE: New Guy, Central Sleep Apnea, wrong machine?
I have to preface with, I woke up at the halfway point, like i usually do, but I actually didn't have terrible gas, so I didn't stop, i just kinda put myself back to sleep. Kept it on for 7.5 hours!! woo!

It does show ahi of 2.x / ahi, but they're all (except a couple) hypopneas, and they're all the same. Does this count as a Hypopnea? They're *mostly* all like this, all exactly 10 seconds, and it seems like regular breathing in and around it

Coming along nicely, and I think this is just the beginning. I mentioned before it looks like an EPAP max of 8 could be plenty, and it still looks that way, especially if you were awake during that early pressure increase at 01;15. Really good to hear you're getting more comfortable, and that is in-line with some other member's experience as well.

Sounds like you got some good progress. Kudos. Have a Happy New Year's Eve and '18.

Do you think having that large of a pressure support gap, epap @ 8 and then whatever the big blasts were, big ipaps lol, having that large of a gap is gonna do The “wash out the co2” thing and make me all dizzy? I thought that’s what did it. Originally on my BiPAP it was 4e and 10i and it was really screwing me up.  .

RE: New Guy, Central Sleep Apnea, wrong machine?
I'm glad you had a better night and kept the mask on. You have some leaks still, I wouldn't fully trust your stats column, until they are fixed. If you get the minute vent and tidal volume chart up, we can see the areas between the leaks. The AHI number becomes redundant when looking at CA with an ASV, It only shows the obstructive side.

To look at how CA are treated. This is the max PS that the machine goes to. On first look, it doesn't look like a ruler was put across your max pressure. To me that means you aren't choking the machine down too much, there are still variation of pressure on each pressure rise. If it was choked down like some I've seen, it would look like there was a line ruled across the max pressure. discounting for the epap rise and fall. The tidal volume and minute vent chart will show how the air volume is going. If your minute vent is fairly straight you are getting enough o2, if there are big dips in the tidal volume and minute vent there are issues.

Leaving obstructive aside, I have the opinion, whether it's right, wrong or too simplistic, can be debatable. If your breath rate per minute is normal with a normal tidal volume. You are getting enough O2. Otherwise your body would breathe faster. When it gets too fast, there has to be an intervention of some kind, as it would appear that there wasn't enough o2. A faster breathe rate and smaller volume, indicates there can be a mechanical problem.
