Some things are simple, if not buried in the details.
1. read up and then ask here before buying.
2. for "most" people a regular APAP (auto machine) is fine, for some of us we need a BiLevel machine. I you go through insurance and it turns out you need the BiLevel you can just bring back your regular unit and pick up the BiLevel-it's a rental. If you buy outright then you are left with trying to sell it in the gray or aftermarket and buying another unit. This can be a risk/reward kind of thing and you "may" end up spending more.
3.Machines will say if they have a humidifier and heated hose, ask here to be sure once you figure out what you think you want
What you think you want:
1. data capable-for sure
2. ResMed or Resperionics- they "do" the same thing for treatment. How they do it is different and some people like each and others don't really care. They will both treat your apnea, you will only know one is better than the other for you if you try them. I have heard people talking about liking on verses the other, but can't remember anyone saying they changed because they could not deal with the first machine brand they got.
3. Tolerating the machine is the big thing, once treated will you use it? for some this is a big issue, others take to it like a duck to water.
4. there are many settings on both machines to help you tolerate therapy
5. Auto titrate is just basically giving the machine a range of pressure settings (5-15) and it will monitor you and adjust within that range to the pressure you need right then. Fixed CPAP sets one pressure and ALWAYS stays there. The auto machines can be set to fixed, but the fixed cannot be set to auto.
6. your doctor will monitor your machine and should have you bring it in to look at the detailed data, do not expect them to do everything, they just don't have the time and much of this will be what makes you comfortable and they just cannot know that.
1. read all you want and then just pick a brand. Your Doctor/DME will have one they work with mainly because they are used to the software from that vendor and this has nothing to do with your case personally. Find out which brand they suggest and make life easier for them and you.
2. verify that it is data capable and has a humidifier and heated hose (don't "need" but makes it nicer bay far"
3. decide if you use insurance/rental or direct buy. Flip a coin if you have to, your call based on risk of needing another one (most are indeed fine with the first one)
4. you could also buy the machine with insurance and mask on line (most offer 30 day trials)
5. stick with this thread so we can follow how you are doing and remember what you are doing
6. many here are happy to help, we will get it working
7. you will need an SD card reader, you may already have one on your PC, if not they are under $10
8. sleephead software is free, you will need to install it. At first just so you can show us graphs of how you are doing so we can make suggestions. Pick it up as you go, you will "get it" after a while.
