http://www.resmed.com/fr/assets/documents/product/s9_series/1013916_s9-autoset_white-paper.pdf I was reading that Resmed has updated the AutoSet algorithm to detect UARS. This peaked my interested. I have a S9 AutoSet which is about 5 years old and it is terrible at UARS detection. Any idea when thi...

I hope you had a great time! Happy B-day.

Your situation is something I can relate to - once fit and active ended up in a wheelchair, heart infection and 20kg underweight. 9 months later I'm walking about 5km a day and started mountain biking again (all be it very short/flat runs). I dont believe there is simple answer however you might fin...

Just sent you a PM.

I'm still wondering if central apnoea is emerging when I actually treat obstructive or resistance issues. The trend seems to be, when I up the pressure or use a FFM, flow limitations stop and centrals seem to cluster (note I use a FFM for only the first couple of hours). http://i1382.photobucket.com...

Thanks - good to get first hand experience.

Hi, I was researching swallowing air while on positive pressure as it is something I'm experiencing. Barry Krakow (https://www.youtube.com/watch?v=KSZ36gfLhpY) goes as far as suggesting ASV for some patients as a last restore. Does anyone know why ASV technology would actually help with not swallowi...

my thinking is that's where the centrals are coming from... his respiratory reflex "passing out" as it were I was thinking about it. The tidal volume should be a key metric, i.e. if one is hyperventilating, breath would be too quick and/or deep thus the greater volume. The two nights do have differ...

Last night (before I read your post), I lowered the IPAP - 12 and kept the EPAP of 5. http://i1382.photobucket.com/albums/ah277/gary1001001/13_zpsf34e3b1d.png As you can see, the centrals are completely gone however the crappy flow curve returned . I also felt crappy this morning - hit by a bus. htt...

you may just be hyperventilating yourself with that 11ps. Yea, thats something to consider. It looks odd having an EPAP of 5, but is just felt so much easier to breath. After reading this wiki entry on UARS, http://www.cpaptalk.com/wiki/index.php/Upper_Airway_Resistance_Syndrome it made some sense....

I've been trying a Bi-Level machine (resmed S9 VPAP S) to see how it feels. The short of it is, its great. Much easier to breath and its really cut down on flow limitation events which may have been linked to UARS. Its early but I also feel better. However, I've noticed a sharp increase in central e...

interesting. I guess the only difference between models is the mainboard and software. Most likely just the software...

have you ever swapped out motors or mainboards up and down the range?

Old thread but....

Any idea if the fans/motors in the S9 series are interchangeable? I.e, are the VPAP motors the same as the elite or autoset?

It just felt like the EPR didn't really detect when I was breathing in. How does Bi-flex from respironics compare? More sensitive at the switch from out to in?

Over the last few weeks I’ve been monitoring what helps and what hinders. I believe the S9 Auto is almost 100% effective at treating mild apnoea, however there is some kind of UARS that is really causing the non-restorative sleep. http://i1382.photobucket.com/albums/ah277/gary1001001/11_zps022df7cf....
