Obst & Central Apnea - on ASV. why do most say- resmed vs dreamstation auto sv?

That 95% number on sleeyhead etc, is that or does it mean that is the pressure the machine is at 95% of the time?

If so my machine seems to be always maxed?

The 95% pressure number means you were at that pressure for 95% of the night and under.  
Note the “and under.”

The 95th percentile is the pressure that is exceeded only 5% of the time...that is exactly the same thing OpalRose said, but I thought it might be easier to understand.

What was your experience with lower EPAP pressure? Yesterday we talked about using the ASV mode rather than ASV Auto. I was kind of curious to see what a fixed EPAP might do for you. We should probably take a closeup view of these UA events and see if we can decipher what is going on. No more than a 2-minute segment with flow rate, mask pressure, snore and flow limitation.

I will do the reg ASV setting tonight or whenever,   I have no problems changing up etc.   Willing to try anything.   Guess it would take more then a single night to see whats what?    Ok here is a screen of a section,   hope i grabbed whats needed - when I do the reg ASV vs ASVauto just do the settings the tech guy put in ? EPAP - 13 / Min ps 3 / max ps 12? do you think a diff mask might change things?

Just noticed I still had the lil pie chart on.    while I do like pie,   it is not needed on screenshots

I think around the same time

[Sleeprider]

Have you ever tried initial titration pressure settings with the ASV?
ASVauto
EPAP min 5.0
PS min 3.0
PS max 15.0
Maximum pressure 25 or 30 whatever the machine allows.

If you have tried this what were the results and what was the lowest EPAP you have tried? If you have not tried this, would you be willing to?

[My3rd3y3]

i'll try whatever. Ive been on this pressure settings for like 3 years since the sleep doc sent me to the diff sleep studies, last one being 3 years ago the asv titration in the sleep lab or split sleep study I forget. This is what she set me too / wrote the script for

[Sleeprider]

Your ASV titration might be useful information if we can get it. I promise we will either use the information constructively or heckle the technician.

[My3rd3y3]

ok let me go over to that other board. i know i posted all my tests etc
let me do some digging

[My3rd3y3]

Found it,   this is the most recent sleep study I had as its only 3 years old.
