Thanks man! I couldn't have gotten this far without you all helping me. And I feel like though I am doing well (maybe by sheer luck) I have a bunch to learn yet.

It seems that in actuality IPAP EPAP and PS all raise and lower independently of each other based on their specific algorithms. Is that correct or am I still missing this?

Hi Galactus,

There are a few basic points on which we need to refocus, so that you will see more clearly how the machine works. After we focus on a few basic points, I think the math I provided earlier will make more sense to you.

Please forgive me for being repetitive in what follows.

Point #1. As you know, the basic definitional relationship is EPAP + PS = IPAP. This relationship is always maintained. It is never violated.

Point #2. Your machine has an algorithm for raising and lowering EPAP. I think the EPAP-adjusting algorithm never messes with PS. In other words, at the points in time when the EPAP is changed, PS isn't changed.

IPAP continues to equal EPAP + PS. In other words, at the points in time when EPAP changes, IPAP and EPAP move in tandem.

If you look at plots where EPAP did change, every time EPAP changed, both IPAP and EPAP moved in tandem. (Looking only at the times at which EPAP changed, you do see that IPAP and EPAP moved in tandem, right?)

Point #3. Your machine has an algorithm for raising and lowering PS. I think the PS-adjusting algorithm never messes with EPAP. In other words, when the PS changes, EPAP doesn't change.

IPAP continues to equal EPAP + PS. When PS changes, EPAP stays the same and IPAP changes.

In the plots you posted, if you want to see the times at which PS changed, these are all the times at which IPAP changed but EPAP did not change. (Looking at the plots, does this make sense now?)

Point #4. There is not a separate algorithm for adjusting IPAP. IPAP changes any time the EPAP-adjusting algorithm adjusts EPAP and any time the PS-adjusting algorithm adjusts PS, maintaining the relationship IPAP = EPAP + PS.

Point #5. There are settings (limits) for how low EPAP can go (the Min EPAP setting, which can be set as low as 4 but can be set higher) and for how high IPAP can go (the Max IPAP setting, which can be set as high as 25 but can be set lower).

EPAP can never be lower than the Min EPAP setting, but how high can it go as it auto-adjusts? It can go only as high as Max IPAP minus the present value of PS, so that the Max IPAP setting will not be violated.

Point #6. There is a setting which limits how high PS can go (the Max PS setting, which can be set as high as 8 but can be set lower). BUT, the PS will not necessarily be able to go as high as the Max PS setting would seem to allow it to go. A low Max IPAP setting can also limit how high PS can go. The PS can go only as high as would not cause IPAP to go higher than the Max IPAP setting.

For example, if EPAP is presently 16 and Max IPAP is 20, even if the Max PS setting is 7, PS would be temporarily limited to 4, because the present value of IPAP cannot be higher than the Max IPAP setting. Only when the present value of EPAP is 13 would the PS be able to go as high as 7 without violating the Max IPAP setting.

I thought that if Min EPAP =13 and Max EPAP = 20 with a Max PS of 7 that 13+7=20 and that with a Min PS of 1 that Max IPAP could =20 and Max EPAP could =19 which left both numbers above my original script."

Yes, in your example, EPAP could be as high as 19, but only if PS happens to be 1. EPAP and PS are separately getting raised or lowered in accordance with their separate algorithms, and I think the EPAP algorithm is not allowed to change PS and the PS algorithm is not allowed to change EPAP.

Keep in mind that whenever EPAP is adjusted IPAP is adjusted by the same amount, so that PS will be unchanged.

Let's take the case that Max IPAP is 20, and EPAP has been adjusted to 15, and PS has been adjusted to 4. (EPAP is 15 and IPAP is 19, which is 1 less than Max IPAP.) In that scenario, if your machine senses that a higher EPAP is needed, it can adjust EPAP to 16. (EPAP raises to 16 and IPAP raises to 20, which happens to be Max IPAP.)

One thing I think you have missed, the max on the unit is 25 and not 20. That was part of my consideration in using 20 as being 2 over my 18 as 18 + 7 (PS) = 25 (in my mind) which meant I couldn't get over the script by more than 5 and couldn't be over the machines 25. Because even if EPAP being set to 13 was raised to my script value of 18 and PS =7 then IPAP would still be at 25 which was the machines max. Did I interpret that correctly or miss the boat?

The Max IPAP setting can be set as high as 25, but when the Max IPAP setting is set to 20 then PS cannot be raised if that would result in raising IPAP above the Max IPAP setting.

Then I read the line for PS Max and it said "This is the max difference permitted between IPAP & EPAP. So if start EPAP = 14 and 7 = Max difference than 14 + 7 = 21 leaving me 4 under machine max. And in the event the machine raised IPAP to 18 (using what I believed was PS's number) then 18 + 7 (Max allowed difference) = 25 which was the machine max.

When the Max IPAP setting is 20, IPAP will never be allowed to go higher than 20; the machine's max capability of delivering a pressure of 25 has no bearing when the Max IPAP setting is less than 25.

I believe this changes once you adjust the max to 25 vs 20, but I am not sure.....

Only if the Max IPAP setting is changed to 25 will the IPAP be allowed to go as high as 25.

Oh no, you don't apologize, you feel free to repeat yourself as many times as you can stand so I can get this. Thank you in advance.

Yes, yes, I see that, only when EPAP changes does IPAP and EPAP move in tandem. Got it, and see it.

So PS doesn't change EPAP, it only changes IPAP, and these are the times when I see IPAP raise on the graph with EPAP remaining wherever it was but showing no movement. Got it, got it.

So IPAP doesn't change itself, it is either changed by PS going up and adding to IPAP whereby EPAP remains the same, or IPAP is changed when EPAP is raised, and then IPAP is raised by the same amount so they remain in tandem. Got it.

So if max IPAP is set to unit max at 25, and Max PS is set at unit max of 8 then 25-8=17 as such max IPAP is 17. Is that correct? Oh wait that would only be correct if PS had adjusted up to 8 otherwise if it was at Min PS of 1 then IPAP could get all the way to 24. Right?

Only when the present value of EPAP is 13 would the PS be able to go as high as 7 without violating the Max IPAP setting.

Perfect, so Max PS is not allowed to raise IPAP beyond the Max IPAP setting regardless of the units ability to exceed max IPAP. I get that.

Yes, in your example, EPAP could be as high as 19, but only if PS happens to be 1. EPAP and PS are separately getting raised or lowered in accordance with their separate algorithms, and I think the EPAP algorithm is not allowed to change PS and the PS algorithm is not allowed to change EPAP.

The Max IPAP setting can be set as high as 25, but when the Max IPAP setting is set to 20 then PS cannot be raised if that would result in raising IPAP above the Max IPAP setting.

So for my 18+7 to work the Max IPAP would need to be set at 25 not at the 20 it is set at because as discussed PS can not raise IPAP above Max IPAP. I got it now.

Yes because otherwise it violates the Max IPAP setting, understood.

I got it, you have explained it for me perfectly, took me some time to get there, but I'm pretty certain I'm there with you now.

OK! So now that I understand, and you see the numbers, what do you think? Is there a reason to change anything at this point? From my perspective it looks like this is going in the right direction. EPAP starting at 13 and moving between 13 and 14 looks ok to me. And IPAP starting at 14 and 16 for 95% and spiking to 18 rarely looks ok to me as well. Do you feel there is a reason to change anything at this point or should I stay where I am and keep recording the week and see where I'm at then?

IPAP can always get as high as the Max IPAP setting.

I see no reason to change. I suggest waiting the rest of another week, watching the data daily if feasible, and then reconsidering.

Ah yes you caught me. I had one of those moments when you wonder Is it I-PAP before E-PAP except after C-PAP?? Grammar jokes what can I say? But yes, you are correct that is what I meant.

Oh you bet I am watching the data, this thread will have all 14 days (first 7 on cpap, next 7 on bipap) before I even think I might begin to be happy, or consider it Smile

Here is today, and it looks like I had a pretty high rise in pressures. Wife asked me this morning to look at the data at around 4am as I had a leak that woke her and it seems that is what precipitated the machine raising the pressures, but I think overall I am looking good so far, and it really seems like this machine is doing it's job, and knows what to do. I'm pretty happy to have gotten this far.

Hey guys or gals, what is VS and VS2? I know it is snore but does it have any significant impact on anything?

And here's today, I am so happy you guys convinced me to get this machine!

VS and VS2. That is some really bad stuff! Just kidding! Those are the 2 different types of snore that PR records. I am not sure the difference but someone more familiar can come by and educate us both.

I don't know. I heard they are two separate indicies about snoring that JediMark discovered when he was working on the Respironics machine for Sleepyhead. I have also heard no one knows if they're good, bad, or indifferent.

My guess is they're a measurement of snoring vibration from two different viewpoints, and doesn't mean much until or unless it gets to the jet engine stage.

What??!! Viewpoints?? Like someone is watching me through my machine at night when I sleep? And from two places?? WTH!!

Seriously though I wonder why they would record them if they aren't of any help. I don't like extraneous information. It IRKS me!! And you know how I can be.

Hey PaytonA, I guess RG is not gonna be of help on this one.
