I just got the results of my CPAP titration study, and wanted to get some input here before seeing the doctor in a few days.
In my original study, my AHI varied greatly between REM and NREM sleep. For example: my AHI during NREM was only 5.1, but shot up to 16.9 during REM sleep. During my CPAP titration study, I only achieved 1.5 minutes of REM sleep total. So while the pressure they had me on controlled the apnea/hypopneas during NREM sleep, I'm wondering if it will be enough to control them during REM sleep. Has anyone had a similar experience? Should I request an APAP machine from my doctor just in case the pressure they determined during the titration study isn't high enough?
My final pressure # was 6.0, and AHI for the night was 0.9.
Thanks in advance for your input!
First of all, welcome to the forum. You have found a great place to find answers.
Since you are asking about an APAP machine before you have a machine, this is a good time to ask and decide. Others have found it is MUCH harder to get a machine swapped once you already have one.
1) It is paramount to get a machine that provides full therapy data, not just "compliance" data. You, your Dr, your Respiratory Tech, whomever are all flying blind without the data.
2) Get an APAP over a CPAP. Any APAP can be setup to operate as a basic CPAP (single pressure), or as an auto-adjust APAP within a range, so it is 2 machines in one. Most people seem to adapt well to APAP mode, some don't. But even if you don't adapt well, you can operate in CPAP mode most of the time, and use APAP mode to perform a re-titration at any time. Pressure needs can change: you gain some weight, you lose weight, you have an allergy flare-up, you get a cold, etc. An APAP will auto-adjust to these kinds of circumstances very well.
When I got my unit in January 2014, all I had to do was ask my Dr. to write the prescription with a range of pressure: 2 numbers, low and high. I don't know what you may have to do, it could depend on your insurance.
Here is a link to an article that gives good advice about selecting machines:
Hope this is helpful,
Good liuck on your journey.
