A flat pressure line

The point that I no longer showed pressure changes was when I turned off EPR and left my pressures set at 9 to 10. I found that using exhalation pressure release ran my AHI numbers higher. Apparently, when I use EPR, the reduced pressure allows my throat to close periodically and my AHI numbers go higher.

It is odd that SH stopped showing pressure changes and the Devilbiss software recorded normal pressure variations as it always has. My pressure is set at 9 to 10. I've tried max pressures from 10 to 12 and higher. With me, the higher the pressure, the more likely I'll have lip flutter and dry mouth and throat. Dry throats stick together and contribute to apnea for me. I'm better off with narrow ranges closer to my titrated pressure and the numbers show this.

It would be more helpful if you could post screen shots. Thanks.

So, would you like me, too, to try on EPR on? Opinion, please.

Hi everybody,
In my present therapy scenario of non-responding pressure, would you like me to change my detection setting from the default with the objective of improving the response threshold of the machine ? (I am a non-snorer on my machine).
I would appreciate opinions from veterans or any one else like myself.

Any updates?

I've started using an Intellipap in auto mode (8-20cm) and am also getting a flat pressure line and many hypopneas showing in Sleepy Head.
Is it a bug in the software, a problem with the machine, or just fine?

Thanks,
Joe

You can use the Smart codes on your machine to get the Devilibiss short version and see if the pressures are reporting the same but I suspect they will...they did in OP here in this thread.

Only way to know for sure would be to use the Devilbiss software and visually look at the entire pressure line.

Devilibiss software will still give you the same vague info
