I do think you need to look for a non-pap solution to your issues.

I’m not a fan of Trazadone, but I would not rule it or as part of the solution.  I think Gideon and I have a common objective to move you away from the PAP therapy as the solution for remaining issues. There appears to be a lot of possibilities.

1. Are my current PAP settings (MIN EPAP = 15, MAX EPAP = 25, and PS = 6) highly abnormal and indicative of some lung or neuromuscular disease? Based on my trial and error over the last year, I can probably lower my MIN EPAP to 13 and my PS to 5.6, but going lower than that causes me to feel like I am not getting enough air. Based on comments by Barry Krakow, I do not think these settings are too unusual (at least with people with UARs). See my previous post above.
   
2. I am a 45 year old 5'10'' male. When I set my PS to 6 or higher, my median tidal volume (TV) and minute ventilation (MV) range between 400 - 600 mL and 5 - 7 mL/min respectively depending on other settings. My understanding is these values are normal for a man of my height. When I set my PS to 0, my median TV and MV range between 250 - 350 mL and 4 - 5 mL/min respectively. My understanding is that these values are very low for a man of my height. Could this explain my need for higher PS? These numbers are for the last year when I started to sleep poorly and felt I needed to experiment with my PS. Unfortunately, I do not have any PAP data from more than one year ago when I was sleeping well and had my PS always set to 3.
