First...what a great source of info. Kudos to the creator and moderators.
I'll try to be brief....
My in home sleep study indicated "severe" apnea with AHI of 30.9.
In lab titration study with pressures from 5 - 13 indicated ideal CPAP pressure at 9 cm H2O.
I only exhibited one central apnea at pressure 5, and one hypopnea at 8, and no other incidents above
pressure 8.
So doctor, prescribed a CPAP machine set at a pressure of 9.
My friend gave me his gently used resmed S9 Autoset with humidifier 5i (with about 2000 hrs run time).
I bought a P & K Vitera full mask (medium) with a resmed heated climateline hose.
I setup the machine in CPAP mode, pressure fixed at 9, with NO EPR, NO ramp.
I don't appear to have any mask leaks, and I get the green smiley face consistently.
AHI for first 8 days of therapy have been as follows:
20.1
10.6
9.3
15.3
23.8
19.6
21.4
16.4
Let me say, even if I see no improvement in AHI, this cpap experience would still be a success, because one of the unforeseen benefits has been reducing my restroom trips from 4-5 per night to 1 per night! That is
incredible. Totally unexpected. I am not waking every 1.5 - 2 hrs for a trip to the restroom.
My original reason for the sleep study is I have had general fatigue for several years that seemingly has no
cause. For the last few days, I don't feel like taking a nap after being awake for 2-3 hours, so I know the
therapy is working.
Questions are: 1. How do I get this AHI down to a reasonable level? Any suggestions are appreciated.
2. Would I benefit trying it in AUTO mode, perhaps pressure min of 7, max of 10?
There don't appear to be any mask/hose leaks. I sleep sometimes on my back, though prefer my right side.
Thanks so much to responder(s).
