RE: advice on setting up an auto-bipap
I may be doing something wrong, but I set the numbers as suggested:

Min EPAP = 10 = your old min pressure setting
Max IPAP = 17 = your fixed IPAP pressure
Max PS = 4 = the difference between your fixed IPAP and EPAP settings.
Min PS = 2 = a wild guess on my part

and got these results according to Sleepyhead
EPAP min 10 and max 15, with med of 10 and 95% of 14.80
IPAP min 12 and max 17 with med of 12.5 and 95% of 16.8
PS min 2 and max 4 and med of 2 and 95% of 4

Is this in fact correct as you'd expect? AHI is down to 1.69 but this is one night's results.

thanks again for all your help.

Those numbers make perfect sense given the settings and the fact that you had been titrated at 17/13.

If allowing the EPAP to go to almost 15 is causing problems with air in your stomach, you could bump the min PS = 3. Chances are that won't increase the AHI

That's good news. Let's hope the AHI stays low.
