Rozenbob, if you're interested in seeing if that auto BiPAP can achieve better results, I would tweak the settings a bit. From what I see here, your EPAP min setting of 12 is fine. I would simply put the unit in auto B mode with EPAPmin at 12.0, PS min 2.0, PSmax 5.0, IPAPmax 17, and see if that drops your events. This will mostly let your machine self-titrate within the current parameters of your prescription, and the lower PS may not induce so much central apnea. The PS on this machine cannot resolve centrals like a ASV machine pressure support, which may be 8-12 cm on a breath by breath basis as centrals occur, causing a breath to be taken. It's your choice, but it may yield better results, or not. You are apparently on your way to ASV therapy.
Another thought. When you are finally prescribed a new ASV machine, I would push for a Resmed ASV rather than the Respironics S/V Adapt. I have seen both machines work well, but more people seem to find the Resmed works with them with fewer adjustments and tweaks.
What to believe?
The post # 11 says that the units in the leak graphics are in liter/min.
If you watch the graphics titled as "leaks". You got two curves, and the top one is an average of 40 . If you got 40 l/min of leak everything is wrong.
That was my first post and now I got even more loss, because I don't know what is going on.
The culprit is Sleepyhead because everything must come with the units .
