ASV and EPAP

[Frebell]

Help with understanding ASV and why Specialist has suggested EPAP may need altering, Thanks

AHI varies between 1 and 30 per hour on different nights, often average about 10/hour

Max EPAP - 12
MIN EPAP - 7
MAX PRESSURE SUPPORT 12
MIN PRESSURE SUPPORT 3

IPAP Median 13.1, 95th percentile 18.3, Maximum 21.3
EPAP Median 8.3, 95th percentile 11.9 Maximum 11.9

Sometimes EPAP needs to be increased if the obstructive apneas (OAs) are higher than we want.
When you evaluate your AHI you need to look at the event category breakdown and not just the whole AHI.
So what to do depends on what kind of apnea events you are having and there are 3 different kinds in that AHI.

Thanks for reply, it would be likely the obstructive are too high, but approx 2/3s of event AHI are full apneas , 1/3 approx are Hypnoeas, and a large amount ( approx 1/2 have no obstructions), and may be due to PLMS arousals. Any thoughts to untangle it. thanks

I have ResScan data but don't know how to post it and cannot get Sleepy head to work and can't even retrieve my past Sleepy head down loads)

As to why SleepyHead won't work...which version of Sleepyhead are you trying and what model ResMed ASV are you using?
Does it use a SD card or a smart card which is about the size of a small credit card?

How high of an AHI are we talking about?
2/3 or 1/3 doesn't tell us what the starting point is.
Is it 2/3 of 30 or 3?

Sorry, this is my first attempt at importing charts and struggling mightily with it .


i hope at least one work or is there a vital link I am missing? http://imgur.com/2TAUW5Q http://i.imgur.com/4kT6ABC.png

Resmed, S9 Pacewave machine , with SD card, Thought I was using most recent Sleepy Head , have deleted it to try and start again, have not checked any backups yet.

The AI's are predominately non obstructive, and can be approximately same proportions even if lower overall level.

Thanks for your time and attention

I am pretty sure that the problem is the S9 PaceWave...it's the PaceWave part.
SH doesn't know what to do with PaceWave data files.

I have never seen any PaceWave data reports. I use a S9 Adapt but the PaceWave is different somehow and I don't know how.
When I go to look it up everything points to UK or elsewhere...where are you located?

If it reports like mine...it doesn't distinguish between centrals and obstructive apneas and puts every thing in the Apnea Index basket and then has the Hyponea Index basket.
I think the assumption is that it treats the centrals and if there are apnea events they must be obstructive.
Your summary report shows AI and HI and no central index or obstructive index...that's the same as mine.
If those are obstructive apneas...then the usual approach is a little more EPAP minimum to better hold the airway open to start with to give the machine a better head start in doing its job.

The clustering is pretty dense which makes us wonder why periods of time with not much going on and then brief period of time with a lot going on. If they are indeed obstructive in nature then we think of either supine sleeping or REM stage sleep. If they aren't obstructive in nature then I have no idea what they would think.

If you have been told they plan on increasing the minimum EPAP...that would be what I would expect if they think that AI is obstructive.
