I would really appreciate any insights into how I can optimize my Aircurve 11 Bipap VAuto settings. I had a chin strap, neck collar and tried to side sleep last night but now my neck is killing me (kinked). I think I have to back sleep but this was mostly side.
I used a Vittera F&P size medium mask, it seemed to work. My septum is deviated and one nostril very clogged. I am not overweight, very fit, but notice my O2 drops when on my back and time to time. I wore an oximeter last night. can share that too.
overall I did rem but woke up at least twice during this less than 5 hours session. Thank you for any advice.
How did you arrive at PS 6.0? That seems to be on the high side. I see a few arousals indicated by spikes in the flow rate, then followed by a cluster of CA. I don't think CA is a major problem here. With the understanding that titration is a trial and error for optimization, I'd like to see EPAP min 8.0 PS 5.0, Max IPAP 18 and Ti Max 2.5, trigger sensitivity on high. For some reason your OSCAR chart is not showing Ti Min, TiMax, Trigger or Cycle. Are you using the latest version 1.5.2?

Thank you for your response, Sleeprider. I picked PS 6 because I really didn't know what pressures would be best so I picked a wider range than the generally accepted 4, figuring I would narrow it down. I will try the 8 and 15 EPAP/IPAP and PS 5, Ti max 2.5 (what should I use as the min?)
My trigger and cycle were set to Medium, FYI. My version is You are running OSCAR 1.5.1+master-dd495e23 but I will update it shortly. I think my Ti Min was 1.3.
Thanks again and any further advice is greatly appreciated.
There is not minimum or maximum PS. Resmed delivers the PS setting all the time. Philips BiPAP machines used a range, but I didn't think it worked particularly well. We recommend Resmed bilevel users start at PS 4.0 and change that only based on observed need. Over-ventilating with high PS from the start is not how it works. PS 4 is the "accepted" PS because it works best for most people, and we generally won't increase it or decrease it without first observing results. To be honest, now that I know there was no process behind your use of PS 6.0, my preference would be to start at 4.0. Here is how Resmed sees it. This is based on S-mode, but the reason for increasing PS from the default 4.0 is hypopnea, RERA or snoring. Vauto takes care of EPAP titration.
