Well, you were provided w/a great device, I assume it was the Resmed S8 Elite II? Or maybe the Resmed S8 Escape II. You really don't want a Resmed PAP w/Escape in the name. The Escapes provide good therapy but they can only report Compliance data which is of no interest or value to you. The Elite and the AutoSet can provide full data, i.e. Leak, AHI, AI, etc.
I was started on CPAP in Oct 2006 w/a Resmed S8 Elite. Great device. I bought out of pocket a Resmed S8 AutoSet Vantage so that I had a PAP and a backup/travel PAP. Then in March 2008 I was switched to a bi-level. I started w/the Resmed VPAP Auto but am now using, since March 2009, the PR SystemOne BPAP Auto w/Bi-Flex. I really liked the Resmed S8s. I'm getting excellent therapy w/the PR S1 BPAP altho the software and I aren't on as friendly terms as the Resmed software and I were.
Respironics just came out w/their new PR SystemOne PAPs in 2009. Resmed just came out w/their equivalent Resmed S9 PAPs in 2010 but they haven't released an S9 bi-level yet.
