Welcome,
A couple of quick observations. You had no indicated Central Apnea, good. You had VERY few Obstructive Apneas, good. Most of your AHI then comes from Hypopneas which you can think of mini apneas, that is not as restrictive as a full apnea. This means if you choose to buy a machine you want to buy a ResMed because the ResMed EPR algorithm can be used similarly to Pressure Support in a BiLevel machine up to the limit of 3 cmw of a CPAP machine. Pressure support is what treats Hypopneas and flow limits which are smaller than but similar to hypopneas. In your case the machine I would recommend would specifically be the ResMed AirSense 10 Autoset for Her. The "For Her" algorithm is what I think maybe the best for you to treat the Hypopneas and the Flow Limits that I suspect are there.
Look at the RDI spikes on your study, they do not appear to be associated with your Apnea events.
Snoring can always cause awakenings or arousals and there is some correlation there.
Look at the Arousals, the small faint marks in the chart above the snores. They seem to correlate with awake, snores, RDI, and obstructive events.
You counted 25 positional changes. I think that is significant. Makes me think of restless leg symptom or something similar. Possibly some mild sleep medicine may help this. Talk to your doctor about this.
I'm sure that with a ResMed Auto CPAP and free Sleepyhead software ( https://www.apneaboard.com/sleepyhead/ ) your snoring (study said light) would be gone and we could better manage your obstructive events. The ResMed BiLevel Aircurve 10 VAuto would also be a good machine choice. It allows much greater PS/Pressure Support which may or may not be needed to manage your events. I mention this because it is a somewhat higher cost than an APAP but not unreasonably so.
The study recommended a Dental MAS or MAD device, these tend to be somewhat more expensive than CPAP and if you get one you want to do so thru a dental sleep specialist, not your regular dentist. But would you like to try a very cheap alternative that may or may not work for you?
Get either a loose fitting soft cervical collar or an anti-snoring collar (no pad in the back) similar to the Dr. Dakotka. For less than $20. It keeps the chin in place (aka the jaw). I have seen this take an apnea patient from AHI of 30+ to under 2 overnight. I don't know but based on the sleep study recommendation it may work. Video yourself overnight if you do.
There are good units that are very low hours available because people give up on CPAP, or someone passed. To essential things to check for on the aftermarket, did it come from a non-smoking environment and does it have low blower hours (not therapy hours)
