First Post: Help analyzing my OSCAR data & other questions

That makes sense, I'll give that a go tonight and see if I can at least get the pressure pops out of the equation and see what the data looks like. Once I get the new study and some new equipment we can see if this condensation is still bad and I'm sure the AirSense 11 Autoset will have even more settings to deal with.

Ok back again for more thoughts

Night 4 (1/21/24):

General Settings:
Climate CTRL: 86 F
Humidity: Off (left the tank in which had a bit of water)
Ramp: Off

Advance Settings: (changes in bold)
Mode: VAuto
Max IPAP: 25.0
Min EPAP: 16.0
PS: 4.0
Ti Max: 2.0
Ti Min: 0.3
Trigger: Med
Cycle: Med
Max Ramp: 45 Min
Start EPAP 16
Mask: Full Face

Sleeping positions: Both sides, and back through the night.

Overview
Turned the min ERAP up to 16 to reduce the low pressure issues from the night before. I kept the PS at 4 and left the max at 25 to give a wider range. It reduced the “Pressure Pops” in my throat dramatically. Overall a better night, much less “Pressure Pops” in my throat when falling asleep or back to sleep. Not none, I end up calling it around 6am and went back to sleep without for another hour of sleep because I was having trouble falling back asleep after a disconnect. I might back the EPAP down to 15, I want to give it a wider range to work with that doesn’t re-introduce so much of the Pressure Pops.


Legit OA

There was one OA that seemed legitimate



Minor Events

There were a handful of these minor events, roughly 9.

To my eye the two you posted appear to be related to arousal breathing irregularities.
Meaning not quite asleep so they don't really mean much except they point to minor and very brief arousals from sleep.
These are common and to be expected and not really much of a big deal unless you see a truckload of them or they are majorly prolonged.

Nah.

Can I call it a "maybe" then?
Sometimes it's really hard to tell and I would rather err on the side of caution if I am going to err.
Is it the tiny breath which is a bit irregular what makes you think it isn't legit OA? I admit it did catch my eye but to me it wasn't as blatant irregular as the others.

Just wanting to further my education.
Thanks.

Nope!

Please, please....I need to learn the "why".
So I will know better the next time.
Thank you.

Me too!

It appears that something happens in the expiratory limb (first red circle) of the breath prior to the FLB . The breathing within the blue circle appears to be wake. The first event would most likely be an arousal that actually becomes wake so no events of any kind can be scored.

More important, obstructive apnea is a phenomenon of inspiration. Look at the FLB. It's the exhalation that has an issue (second circle ellipse). Indeed, he does not really exhale until ~13 seconds later (red #3). So to me, this looks like an awakening, a breath in that is mostly held (as could be seen in a position change, stretch, flatus blast, etc.), completion of exhalation and several recovery breaths.

Got it. Thanks so much. I knew the breaths after the flag were awake/arousal breaths but the little weird stuff (your first 2 red circles) in the breaths before the obvious cessation I couldn't decide if they are indicative of arousal or not. Wasn't normal asleep breathing but also wasn't classic awake/arousal breathing like the breaths after the flag.

This sort of stuff is where I am admittedly weak in...those little subtle differences in the breaths that point to arousal breaths.
I like it better when the arousal is so blatant that a blind man could see it.

Thanks so much for the explanation.

This is fascinating, thank you Rubicon and Pugsy.

Do you guys think I should make any adjustments at this point other than maybe stepping down from 16 to like 15 to give a little more range? Then just let it ride for a week as is?

I've got a meeting on Wednesday with the sleep specialist. Do you guys think it's worth the time and money to do a full on study again? I know I want to upgrade the gear a bit. It's just hard for me to tell what's a good use of time and money and what isn't.

Why not just let your sleep guy do his thing. You'll get a much better relationship going if you avoid phrases like "Some guys on the internet said...".

Meanwhile, if you are so inclined, load 1.20.2024 into SleepHQ and post the link.

That's fair advice, I won't lead the witness on Wednesday, I'll just see how he wants to proceed.

One question for you though.

load 1.20.2024 into SleepHQ

Can you help me understand what this means, Is SleepHQ another sleep software similar to Oscar? If so do you mean just install SleepHQ, then load in the data from the SD card from 1/20 and I assume it has some way to post a link to it's analysis?

It's a site where one uploads their data then anyone you choose can review the whole night's data. There's a free option:

Nice! seems like I don't need OSCAR anymore with this.

Some notes from Night 5
- Even though the data is a lot wilder than I thought it would be I felt like I had my best night of sleep yet. I only woke up once that I recall to use the bathroom.
- I received the ResMed AirFit F20 and this was my first night with it. Overall loads more comfortable than my old mask. The elbow/quick disconnect bit for this mask though is very noisy though and blows air right into my eyes. The charts look like it was super leaky which is interesting because I tested the fit at a pressure of 22 to make sure it wasn't going to blow out, but that elbow lets air free flow so I'm not sure a leak rate of 0 is even possible with this mask?
- I went with humidifier off and no water in the tank, which I'd done before, but for whatever reason with the new mask, no water issues in the line or the mask all night!!
- This isn't new, I've had this the last 3 nights, but man I'm getting so much air in my stomach overnight, the burps are at Frat Party levels and it's even a bit painful overnight and in the morning.
