I purchased an Airsense 10 around that time, but was seemingly unable to use it. I'd wake up choking and gasping for air.
I saw a few ENT's and then one who specializes in sleep apnea. They all concurred that I needed a turbinate reduction procedure. I had that done (RF procedure) 6 weeks ago and have started again with my APAP machine, and it's been about 4 days now.
I have had success in that I'm not waking up gasping for air or removing my mask (see profile), but I can't say I'm experiencing the full effects just yet. That said, I am certainly now able to stay with the program long term.
I was able to see by my sleep reports (Clinical mode), that my average pressure is at about 11 or so, so I adjusted the machine to range from 8-20. I may move the minimum pressure back down a bit as a find it a bit overpowering in the period before I fall asleep, but it's just a matter of seat time for me to get fully used to the machine.
My AHI is now averaging around 4 but I don't know enough about this condition to understand all the data I see in the Sleepyhead reports.
If anyone can give me a clue as to what pertinent data I need to look at besides just AHI, I'd appreciate it!
