Question two: My guess is with leaks these machines (ResMed and Phillips) do not read correctly??
Question three: I take it that a PS of only 1 to 6 is the total range of the ResMed ASV and there are no ways to go higher??
Details:
This is seemly insane.
So the more I fix the worst things get.
My first three nights showed LOW AHIs like .60, .88 etc.
Not once have I shown any obstructions, just hypopnea and Unclassified Apneas
Problem one was I found out that I need to really tighten my AirTouch F20 Mask to stop a leak and to stop the breeze I was getting along with runaway out of control air flow and pressure. (Both on Phillips ASV and ResMed ASVs)
So that was fixed.
My AHIs rate started to up…Sunday I had a AHI of .90, Monday 1.60 Tuesday 1.36.
Again Not once have I shown any obstructions, just hypopnea and Unclassified Apneas
Last night I found a leak in my hose right at the end that plugs into the machine…
Before I found the hose leak I was reading 4AHIs for 3.5 hours of sleep.
I was running Auto ASV, and pressures were seemly running away again, mask pressure as I was trying to go to sleep was hitting IPAP of 20+….
I then turned it off and ran just ASV….still running high so I set the lowest MAX PS at 11, and PS was 6. Its max setting.
This seemed to work for while…
Then the straps let go, so I dug out a new spare set of straps.
I then found the leak and dug out my only spare hose.
OMG the noise I thought was normal got a LOT quiet, so I have had that leak for some time??
Along with that repair I switched from an almost too tight med mask to a large which is more confinable.
Things just got worst, …last night after all the fixes things got even a lot worst.
I ended with a 10.15 AHI and things were a lot worst AFTER the fixes for the last part of the night.
This is the insane part. My guess is with leaks these machines (ResMed and Phillips) do not read correctly??
Here I now hit a wall with the ResMed ASV. With It’s VERY Limited settings.
The Highest PS I can add it limited at 6.
By Titration rules as I am having NO Obstructions and LOTs of Hypopneas and Unclassified Apneas (Centrals) my EPAP is good but I need more PS for a higher IPAP.
With my Phillips ASV I can run a low 6 to 12 EPAP and a HIGH PS as I want all the way to 30 if I want it….it is NOT limited to a spread of ONLY 6.
Seems to control my Hypopneas and Unclassified Apneas (Centrals) I will have to jack up my EPEP along with my PS to raise my IPAP pressure.
I take it that a PS of only 1 to 6 is the total range of the ResMed ASV and there are no ways to go higher??
