Trilogy 100 AVAPS Rate -- I'm Good. Thanks

My Trilogy was swapped out today so it can get it's maintenance and upgrades. The loaner is 2 software versions newer and has a new option in the AVAPS settings.

AVAPS Rate 1-5

This is not BPM because that's separate and mine is set to 7. This only allows 1 - 5. The other settings are the same as before but we have no idea what this is? We set it at 3 for now, but I'm hoping we can figure out what it is before bedtime so I can make sure it's set properly for me.

If anyone knows what it is, I'd greatly appreciate a response.

In the meantime, I'll start searching through the internet to see if I can find it.

Thanks!

Okay -- I found it pretty quickly. From the Respironics Web Site:

The AVAPS feature has been changed to allow for adjustment of the rate.

The AVAPS Rate setting allows you to adjust the maximum rate at which the pressure support automatically changes to achieve the target tidal volume. A higher rate allows the AVAPS algorithm to change pressure support faster to meet the target tidal volume. It can be set from 1 cm H2O per minute to 5 cm H2O per minute in increments of 1 cm H2O per minute.

I'm not sure what the best option is for me. If nothing pops up that convinces me I need it higher or lower, I'll leave it at 3 and see how it goes. I can always adjust it during the night if I have trouble.

I found this very quickly, so you probably did too, but just in case:

Thanks! That is what I found and posted. I *think* I understand what it does, but am not 100% positive that I "get it." I'm not sure what it will actually do depending on how it is set.

Edited: Okay, I've read it over again and thought about it, keeping in mind how AVAPS works. My thinking is that I would be happier with it higher over lower. But 3 is a valid starting point.

Your trilogy 100 without that software upgrade was set at 1 cm h2o per min.

Interesting. Would you be willing to give me an idea of who you are and how you know that? If my Trilogy was defaulting to a setting of 1, a setting of 5 might be very problematic for me (3 even).

I use the trilogy 100 and I have an older bipap avaps. Both machines increase at 1 cm h2o per min. The trilogy 202 and the a30 or a40 had the new avaps feature that could increase 0.5-5 cm h2o I believe. The trilogy 100 has a software update for that feature. I would link from respironics site, but I'm having problems with the site. You could probably call respironics and ask.

Thanks, Boots. I left the setting at 3. The only thing I noticed was a rushed feeling before I fell asleep, but since I get that once in a while, I can't be sure it was that setting. I will leave it at 3 for a few nights and if the rushed feeling continues, lower it to 1. Beyond that, it was seamless that the machine wasn't mine.

Just remember, you might feel a bit "rushed" now .. but try it a few nights. If you feel better or no different, then you will probably adjust to the "rushed" feeling. But time will tell. It's amazing how much our bodies can adjust to our therapy.

But glad it went well otherwise. Hang in there and keep up the good work (staying on top of your therapy).

Thanks, John. I was planning to leave the AVAPS rate at 3 for a few nights and see if things settled down.

One thing I did notice though. On my Trilogy, the IPAP would always start out 3-4 cm higher than my min. If my min was 15, it would be at 18 or 19, then slowly back down and settle at 15. After a LONG time, it stopped doing that and my min was where it started out.

This loaner did that last night and since my min is 18 now, it was pushing at me at around 22!

What's so astounding, to me anyway, is that 22 wasn't awful at all. I was more comfortable at 18, but 22 wasn't trying to kill me!!

As I understand it, ResMed is also coming out with assured Tidal Volume support later this year implemented in their next generation of S9 VPAP Adapts (or maybe it's S10?). Sounds like a good thing to have that volume support for your lungs - it would probably help blow out the CO2 and incorporate the correct amount of O2 into your bloodstream.

We talked about that a little in another thread a month or so ago. Many of us are interested in Resmed's technology.

Which reminds me. My RT never told him if she talked to her Resmed Rep and what he said about the machine. I'll have to remind her!
