I have experimented with reducing the EPAP from 3 to 2 to 1 to 0 and 1 seems to be the best. Any suggestions as to what pressures to use to minimize my events? Any other settings I should try differently? I used to be under 1 so I am wondering if I can get back to that level as it gave me lots of energy to get things done. See also screen shots I attached.
Please help me.
Many thanks!

RE: Finetuning settings to prevent CA
A few things to address your question, it looks like Ramp is off and EPR has been reduced to 1. While it's possible to minimize pressure range even more, it really is not needed. The recent chart I saw had 4 CA flags in 8 or so hours, so there's not much of anything there that needs addressed on the Centrals.
I think there's some leak control work to be done if you must fine tune something. We'd need a standard screenshot no zoom to see leak patterns.
Unless there's some computer issue blocking use of OSCAR, I'd go for the upgrade from Sleepyhead. Sleepyhead has not been updated for several years, and there's quite a few upgrades the programmers have gained with OSCAR. It's far less buggy and more accurate.
INFORMATION ON APNEA BOARD FORUMS OR ON APNEABOARD.COM SHOULD NOT BE CONSIDERED MEDICAL ADVICE. ALWAYS SEEK THE ADVICE OF A PHYSICIAN BEFORE SEEKING TREATMENT FOR MEDICAL CONDITIONS, INCLUDING SLEEP APNEA. INFORMATION POSTED ON THE APNEA BOARD WEBSITE AND FORUMS ARE PERSONAL OPINION ONLY AND NOT NECESSARILY A STATEMENT OF FACT.
Thank you for your time looking at the images, I upgraded to Oscar and have attached a few images for you to look at. I also added an image with EPR at 2 cmH2O showing many more CA's.
I do wake up with a very dry moth recently. Maybe I need to tape my mouth shut like I read some people do.
Please let me know what I can change to find the best settings.
I would like to see a few 3-minute views, Please squeeze the leaks, flow limits and pressure a bit to fit it in. one of the views should be normal breathing.

You mentioned previously using EPR of 3, it would be good to see some examples of that as well. As Gideon noted flow limitations would be of more value than tidal volume.
