A Zero AHI Really IS Possible. :D

It ramps up when it perceives the beginning of a problem. Even a problem that isn't defined as a flow limitation, snore, or other recorded event. There's nothing wrong with preventing events is there?

Congratulations on passing OSA 101 with flying colors. You excelled in problem solving, you showed wonderful creativity, your determination deserves an "A".... and your attendance was great

Cool, CG.

Thanks, RG. There's no way I could have done it without all your patient help and guidance.

Sincerely, and from my heart - Thank you.

Agreed, there should be some flags first. It registers the event and then responds. Something is wonky.

Maybe try a newer version of the encore software.

From what I understand (and someone with more complex knowledge of auto algorithms can feel free to correct me if I'm wrong), when the auto senses variable breathing, under certain circumstances, it ups the pressure a tiny bit to see if the variation is normalized. It could be that it is trying to decide if the variable breathing is related to REM or to what could possibly turn into an apnea event - I'm not sure. At any rate, this "checking to see if a higher pressure normalizes things" is how it prevents apneas, and the precise reason why people who say autos only respond to events once you have them are so very incorrect. There is no data flaw. The machine is doing precisely what the algorithm is designed to do (preventing events, not just reacting to them once they happen), and doing it well.

The machine is not defective.

CollegeGirl set her minimum pressure to 11. The machine once turned on goes directly to 11.

Why did CollegeGirl do this, based on her information of her titration or information that she gained from her Encore Program, she/Dr was able to tweek her treatment to her advantage.

I don't use the ramp either. For me, it's a waste of time since I tolerate my pressure just fine.

That does not explain why her CPAP jumped when there was no events.

Let's restate the obvious from her data. The low pressure is 11, the machine jumps up to 12 or more (hard to say exactly to what pressure in the pic) yet there are no events. The solid pink line represents the 11 base pressure. Something is amiss.

Sammy, my post two or three posts back explains exactly why it does this. If there's something you don't understand in that explanation, feel free to ask.

Thanks College Girl, I didnt see the post. I had thought about that, but I thought that was only with Resmed machines. That would explain it. Perhaps your breathing pattern is so regular that the machine can easily detect any variations and adjust to it. Have you checked your My Encore Software and seen how variable your breathing is?

CollegeGirl · Post by **CollegeGirl** » Tue Apr 17, 2007 7:42 pm

I checked that out, just for you, Sammy. Average variable breathing 34%. That's not something I look at often, because when I got here, I was told that you can't really tell anything from that number, as it's impossible to tell what is REM-related and what is event-related. I hope it helps.

WOW-thougt I was getting good numbers-you are an inspiration to keep tweaking!
