Help Interepreting my first Results?

Hi, I'm newly diagnosed with OSA and have found these forums to be an amazing treasure trove of information, what a wonderful resource.
I was just wondering if someone would like to check out my sleep data - mostly to see if I'm vaguely correct in how I'm interepreting it. These are the reports from EncorePro 2.2:

Last night - The longest nights sleep I've ever had!

I'm 38yr old female in Australia, diagnosed with OSA (ahi 48) a month ago, and have been trialling a Respironics System1 w/humidifier, paired with a SwiftFX mask (medium pillows) - I'm very comfortable with the combination. I've only needed very low pressures - I start at 4.5 and tend to peak at about 10 (during my sleep study they titrated to a teeny 6). I don't seem to have any issues with leaks.
Some atrial flutter was noted in my study, and encorePro reports a few episodes of periodic breathing each night.
My sleep doctor was 80% sure I'd be a good candidate for an oral appliance, however wanted to get a good solid month of data from an APAP machine first (in Australia you have to pay for all the equipment out of your own pocket, so can't afford to get it wrong! An oral appliance is about $1500.)
I realised the other day that I'm not entirely sure what he's hoping to see in my stats that would mean I'm definitely suitable for an oral appliance - I was assuming low CA's and low pressures...?

As I said, I've been very comfortable wearing/using the equipment, but am still very tired. There is a big improvement though - supposedly I'm looking more alive and less haggard now, and I can drive without being terrified I'll crash into a tree. I can also stay awake through 75% of a movie now, and maintain short but lively conversations without dozing. After my first night I had to stop taking my blood pressure medication as my BP plummeted (I've been treated for severe hypertension since I was 18, and had a stroke).

After going through the stats, I am interested in the increase in Clear Airway (aka central, possibly) apnoeas, as my pressure increases. I get to about 5 CA's an hour. From my reading here, they're probably insignificant as you need "quite a few" in order for them to be worth paying attention to? I'm not a very active sleeper, I tend to lay on my back fairly solidly all night.
It seems that as my pressure increases, so do my CA's, and then my AHI goes up - my OSA's are kinda stable. Would this indicate that straight CPAP would be more suitable?
Overall my AHI is under 5, so my therapy is clearly effective. I should probably not look at any of this data and just get on with life!

Of course I'll discuss this with my doctor, but I'm not seeing him for another week, but I find all this data extremely interesting and was curious if anyone had any input

Hi, your results are similar to my. I started CPAP 7 weeks ago. Before CPAPing I had AHI of around 50. Afterwards it dropped to around 3. I am also at 6 cmH2O, but I think that it should be raised (to 8?) b/c I am a bit dizzy during the day. A mandible procedure costs in my town about $2,000. After its made by a technician and installed by the dentist all future service is free. But I am not a candidate b/c I don't have enough teeth left. Have you read about the TMJ complications that it could cause?
