Agreed with Sleeprider. If you're not actually treating Central Apnea, the VAuto will be better, more comfortable, likely with better breath patterns during sleep.

RE: Should I change from ASv to VAuto BiPAP?
This is my current one for last night.
I asked on here before and u suggested these settings Mode: ASVauto in another thread. " EPAP min: 5.0 EPAP max: 8.0 PS min: 3.0 PS max 12.0 "I have changed them a bit since, but will you still suggest these settings with the latest chart I linked along last night here. Or someother change?
Well I had some centrals before when I was on my old Cpap, and I thought that was the reason to still feel tired, then I read about the Asv and it sounded as an upgraded version of Bipap that would treat everything you have, so I bought an Asv thinking it would treat those few Ca's I got and if I had Rera or uars they would also be fixed even though I didn't knew back then if I had any Rera's or Uars and I actually still don't know, but I thought with the Asv everything is fixed.
But today it's 6-12 months ago I bought it or something, and I am still tired and struggling with it, I see my ahi is almost gone yes, but my Flow rate seems strange at times, and not in synch as a normal pattern as not the same all the time.
are these grafs better or would you like something else to get a better picture? will you still say that a bipap vauto as I talked about in this thread is the ideal for me? or something else? or should I change the settings back to what you suggested or something else?
can you see on my grafs if I have rera or uars or something else that isn't Oa. back on Cpap I only had 5-15 ca's an night so not above the 5 ahi as people say, so I thought it didn't matter because I was still tired.
Could the cpap have given me the few centrals back then due to the possitive pressure support only, so having a hard time exhalation. I link some old charts also from back on the cpap.
I could also try and call the center that did the test back in the day, and hear if there were ca's also? or it was only Oa. I bet that test shows how my Apnea still is today?
is it important to have a normal pattern on your Flow rate? and can they be the cause for still feeling tired, and other stuff? I got chronic headache also. Bipap vauto might help me to get a regular pattern right?

If you're not treating central or mixed apnea, there is no good reason to be using ASV, and it appears to be resulting in some abnormal paced respiration based on the November 24 graph. The May 10 graph has a lot of settings and statistics blanked out, but the period selected shows very high pressure support, and if you're not treating centrals, the Vauto would deliver a fixed pressure support that would probably be more effective for obstructive apnea and flow limitation. These graphs are not very useful to know why you are using these settings or to suggest what might improve your results and sleep quality.
I don't know if you get a notifikation if I click on reply, or it's better to do quate reply.

Your recent results indicate apnea is fully controlled and these settings seem to be appropriate. I'm not concerned with the appearance of graphs, although, these look fine. The ultimate objective of therapy is that you are comfortable and we minimize any disruption of sleep arising from the therapy. Your qualitative comments on that therapy comfort are missing.

okay Thanks to hear, but how about the Flow Limit shouldn't they be lower, they often peak at 1,0 or close to.
" Your qualitative comments on that therapy comfort are missing. - What do you mean by that?
But I still feel tired, and my flow rate pattern still seems off sometimes, so you still don't think I should go over to bibpap vauto instead or my current asv?
I think your ASV machine can be set up to operate as a standard Bi-level machine if you feel it may be more appropriate or want to experiment with V-Auto.
I see you are concerned about the Flow Limitations graph. Search causes of Flow Limitations during sleep to see causes of Flow limitations other than what can be addressed by PAP therapy.
Consider what may be keeping you from quality sleep other than apneas. With 0.00 AHI it is not sleep apnea causing poor sleep. Does the machine irritate you? What factors other than apnea events may be causing you not to sleep well?
I only give suggestions from experience as a fellow CPAP user, not professional advice.
Your flow rate does not show much flow limitation and your 95% flow limitation (the statistic we actually follow) is 0.00. With the Vauto, PS is more stratight-forward and fixed. We simply increase PS and it is provided every breath. You are using ASV, so the device uses PS from minimum to maximum, primarily to maintain minute vent. If you think you would benefit from a higher minimum pressure support, than by all means, try 3.4, 3.6, or even 4.0. You will always see some flow limitation on individual breaths with ASV as it applies pressure support to make a breath, even when spontaneous effort is not present. This causes some flattening of the inspiratory curve at almost any pressure. Take a closer look at your breaths with flow limitation using the mask pressure and flow-rate charts and I will assure you, the PS is greater than 3 on every one of those breaths. This is a feature of ASV, not a bug.
