Im new but I am a reasearcher. IMHO APAP is way better than CPAP. Few reasons.
1) Your AHI index is probably worse on your back than side.
2) Straight CPAP has to be set for the worse senario (on yoru back)
3) Over treatment can cause to central apnea's
4) Your muscles dont work a all with the same pressure. Changing presure can cause them to work and tone them thus possibliby making things better.
5) You dont need the same pressure all through the night so why tolorate it if you dont.
6) Set a tight range and you wont have to worry about arousals. I heard people running fro 4 -20 thats no good. Find your upper limit and ask your doctor to set 4-5 CM below it.
7) My AHI index on auto is 0.6
8) My 90% pressure is 12, titration set me at 14.
