New to the forum, have been trying to find this info, sorry if it has been repeatedly asked and answered...
Problem is the curve for lowering pressure after a rise in pressure.
Have used Resmed S8 Autoset successfully for many years. As this was paid by myself and I asked my doctor could I please have a "free" one (Swedish health care permits one CPAP on free loan for anyone with severe apnea). I got my S9 autoset and a new mask. Got a RV/Motor home and want to keep one of the CPAP permanently in the RV.
Thought I was going mad for a few nights and went back for a mask change. Had severe leaks where I had to turn CPAP of to reduce pressure. Turns out that the next mask had the same problem.
Changed to S8 and it worked beautifully.
Back to the clinic. They tell med S9 has a "slower curve of settling back after stopping an apnea occurrence". So basically if I hit 17-18 (yes it is that bad), it takes some 30-40 minutes to reach 7 again.
Not possible to adjust. Now I believe the knowledge in this group may give me a more hopeful answer. I want to have a similar "curve" as in the S8.
Otherways a total waste of time and a worry that when my S8 finally goes dead, I will be in a very bad place. S8 obviously not produced any more as I was not able to change for that. And since I do some air travel the lighter weight of the S9 would be great.
Any thoughts and recommendations appreciated!
