[CPAP] Recently Diagnosed, Just started treatment, looking for advice.

[ProlificProkaryote]

Background: 

A few years ago I remember experiencing waking up gasping for air, happened once or twice a month, for about a year or so.  Got married last year and my wife mentioned hearing me occasionally making sounds like I was struggling to breath, although so far snoring hasn't been a huge issue.  This on top of just not feeling rested in the morning led me to take an at home test (lofta).  Decided not to go through my usual doctor because I thought that would 1. take longer, and 2. cost more since we have high deductible insurance.

Lofta test came back with a diagnosis of: "Obstructive Sleep Apnea (G47.33) - Mild to Moderate based on pAHI=14.4, pRDI=21.0 and O2 nadir of 88%"

Got a resmed10, F30i (not too sure about this choice, I felt like I often get nasal congestion and I didn't like the idea of taping my mouth up, so far it's seemed relatively comfortable).

First night I used the default settings, felt reasonably comfortable and fell asleep without too much trouble, but  woke up a couple hours in, and felt like it was too hard to breath, so I ended up taking it off.

Second night tried to adjust some setting for more comfort, turning on EPR to 2 raised the minimum pressure, and lowered the maximum (although I was never hitting it). Slept for a bit longer than the first night but still ended up taking it off a few hours later.

Despite the diagnosis of OSA, I'm not seeing OA events in the data, mostly CA events.

Looking for any advise you have in interpreting this data, and what settings/adjustments you'd recommend.

what was your pAHIc on the lofta study?

[ProlificProkaryote]

They didn't have that metric, not that I could find.   I've been trying to see if I can find more details, but so far no luck:

Here's what I got back from them:

Part 1
   

Part 2
   

Also huge apology for the typo in the post title.  That's embarrassing...

What typo in the title?  

I bet you were absent the day your 3rd grade teacher taught that word.

If you call Lofta, maybe they can tell you whether you had central apneas during your sleep study.

[ProlificProkaryote]

I found the process to request that from Lofta, waiting to hear back.

Did the Lofta test include wearing any effort belt around your chest? This is the typical sensor for the Central Apnea others are asking about.

[ProlificProkaryote]

No belt. There was a sensor adhered to the chest, but I got the impression that was mostly for orientation.

[SarcasticDave94]

OK copy, they may not have included the Central metric in testing, I'm not certain though. However this CA seems to be your biggest item at the moment.

Consider a setting edit that may help avoid these CA. I would first avoid Ramp and probably reduce Max pressure to 15, which you've not hit anyway. I would also reduce EPR to 1 at some point. The Min 8 or similar is OK.

The goal of these edits is trying to minimize some pressure swinging effects, which can enhance CA events, possibly by way of washing out more CO2 than your body is expecting. CA could also have been in force during the sleep study, but if they weren't monitored, there's likely no stats for this aspect.

Lofta got back fairly quickly. 

"pAHIc 3%" was at 0.3 per hour, only 2 events.  See attached.
