AHI index has taken a nose dive the past month

Here's last night. My numbers were much better. Thoughts moving forward? I did ask my girlfriend to tell me to roll to my side if i was on my back, and she did a couple of times.

That seems to be progress compared to where you started from. I'd let this stand until next week, then look at the trend. Moving things around too soon can create more CA, and your OA is in decent shape here. There is room for improvement, but no need to start dial winging.

Thank you, Sleep!

I'll do as you suggest and report back next week some time. No dial winging...that's pretty funny

One thing I forgot to mention earlier was the EPR, or lack thereof. Initially, it was moderately difficult to exhale. This feeling went away after a short while, and I was off to sleep.

At low pressures, EPR can complicate things, because it drops EPAP pressure low enough it can allow the airway to close. For example at EPR 3 with CPAP pressure at 7.0, EPAP is 4.0. As treatment pressures get higher, this problem may be less, but EPR works a lot differently form AFlex or CFlex, and is much more like bilevel.

In bilevel titration, the EPAP pressure is increased until obstructive apnea is controlled, then IPAP is increased to control hypopnea, and RERA. So, you can use a Resmed machine like bilevel, but you have to understand that you could end up with higher IPAP pressure in order to continue to control OSA when using higher settings of EPR. Does that make sense?

The first part made perfect sense. I had to read the second part a couple times, and look at definitions, before my grasp became tighter.

Thank you so much! The education is fascinating!

Numbers were even better last night. OSA'a were WAY down, while the centrals are still a little high.

Numbers are getting better by the day. We're on to something, here.

Thank you!

I have posted the past week of Sleepyhead data to photobucket. Please give me your thoughts.

Thank you!

I posted about 9 days of new data. Can you take a look at it please?

Thank you!
