Noob- Large flux in AHI?

You are using BiPAP pressure of 13/9 on a Dreamstation BiPAP-S and experiencing CA.   The simple solution is to reduce pressure support, which should significantly reduce CA, and possibly increase EPAP pressure which can resolve OA and hypopnea.  If you are comfortable with making setting changes, then set EPAP to 9.5 and IPAP to 11.5 and let's see where that takes us.  This gives you a pressure support (PS) of 2.0 cm. This should be comfortable, while eliminating a significant part of the CA you are having with PS of 4.0 cm.  At the same time, raising the exhalation pressure (EPAP), will give you a bit more support to deal with OA and hypopnea.  

We don't really need to see data to suggest this. Your problem with PS is very very common.  On the other hand, there is a reason you have a BiPAP and not CPAP.  Were there centrals in your sleep study or titration?

Hello Sleeprider!
Thanks for the suggestions. Unfortunately, my pressure is locked so I can't change it.  Dont-know
I was given a Bipap as I was having a hard time dealing with a constant pressure.

send an email and you can get the clinician manual.  

That will make you a Houdini on your machine.  Then you can do as SleepRider requests.

In order to better advise you, download SleepyHead software, then see the tutorials below in my signature line.  This will guide you on how to organize your graphs and upload here.

Thanks!

Here are the attached graphs. Any input would be great. I am going back to see my doctor next month, but he really isn't one to answer any questions techy wise and just pushes one out the door with advise to loose weight and stop drinking  Sad Being an active runner and not prone to night caps, this does me little good.

Oh right. My study did not show any central apneas, or obstructive ones for that matter, which I found odd as I was diagnosed with obstructive sleep apnea. 
My initial diagnosis was an AHI of 17 from Hypopnea events
And I miss read my script, it is min EPAP of 9 and max IPAP of 25

I have a feeling that if you push the control knob and ramp button at the same time, you will find your settings are less locked than you think.
