I wake up all the time gasping for air, and it has even become a joke in my family. 6 years ago I got a sleep study done and was recommended a CPAP, but I just couldn't afford it. Fast forward and now my sleep quality is so poor I am willing to reconsider. My insurance isn't great and I do not have the time for another sleep study, so I plan to buy a S9 Autoset or similar (good data tracking), and pay out of pocket. I have. Physician family member who will write my scrip as needed.
Begging the question: aside from the CPAP machine, what do I need!?
I have no idea where to start with masks, hoses, etc.
Also is software an additional costs or is there something open source and hopefully Mac friendly?
As far as initial settings and calibration, I received the following advice on the Reddit:
Well there you have it --- now what?!Get yourself an Auto Machine with data logging. Run it for a week with the widest pressure settings, then look at the data. You'll likely have a lot of apneas early in the night then the machine will reach a pressure where they'll reduce down significantly. Take that pressure and make it your new minimum. Most software will have it listed as something like the "90% pressure".
Rinse and repeat until your AHI is <5.
The biggest thing to be wary of are Central Apneas: when your brain "shuts off" your breathing. Too high of pressure can cause it to happen.
Go on CpapTalk and ApneaBoards: they are a lot more active and have a lot more information on how to get into the "secret" settings menus.
