Trying out ASV could use some help...

Trying out ASV could use some help...
Hey guys, 

Got my hands on an ASV for EXTREMELY cheap so I thought why not give it a shot? Was on an Air Sense for Her previously and while my numbers were good I still felt tired and not with it. I've heard Dr. Krakow said ASV can help people better than a regular CPAP so decided to give it a try. 

Last night was my first night and I've attached my results. While my ahi looks fantastic, I kept waking up through the night. I think my humidity was low. What really has me worried is how low my respiratory rate got down to. It says it was at 6 breaths a minute at one point! Yikes! 

Should I not give the ASV another shot? Do my settings seem fine? When I zoomed in I noticed when I was actually sleeping well my flow rate seemed less limited so that's good? My I:E ratio is much better too and my Tidal Volume is bigger? 

What do you think?

Really getting increasingly freaked out by that low respiratory rate... I hope i didn't cause any damage to myself.

The area of concern I would have with that low of a respiration, is oxygen desaturation.  You might wish to consider obtaining a recording oximeter.  Something like the CMS-50F or a Wellue device.  Both are OSCAR compatible.

I should mention that if you decide to purchase one, search for discount coupons first.

Let's look at some different charts.
Events
Mask Pressure
Minute Vent ResMed ASV tries to maintain this.
Tidal volume
Respiration Rate

Please fit these onto one page.
In addition to the full night view provide a couple of 5-minute views of the areas you question.

thanks

I had a lot of aerophagia last night too with the ASV... Honestly thinking of just not using it again... I'm a little freaked out by the results.

in your apap flow rate graphs, have you seen a pattern like the 'whacky' one around 4:24 on your 4/30/21 asv screenshot?

Never like that. I've seen stuff like this

This is from an APAP night, but nothing as weird as the breathing in the one from the ASV.

Not uncommon IMHO
look at the detailed chart that starts at 422
You see each breath drawing a large volume with a breathing rate of 6. On the right of the page you see a faster breathing rate and a lesser volume for each breath. All this time the algorithm is keeping the minute vent constant as it should.

ASV works by raising PS which can aggravate aerophagia.

So everything looks normal? Should I give ASV a go again? Do you think it can help with UARS?

I really just got a crazy deal on this machine (200 dollars CANADIAN, brand new!) so I thought I'd try it out to see if it would help. I do know that Krakow's theory's are outside of what regular sleep doctors think though...

I think whether or not ASV will work well is if you've had lots of Central Apnea. CA combat is what the ASV is made for. Having used it as well I know it can tackle all Apnea except flow limits. And yes it will feel a bit different than other PAPs. Your events are very low with it. You might be able to back off the top pressures as in IPAP by lowering the PS Max some, if it needs to be done that is.
