Help me interpret my second Sleep Study results

[YouTakeMyBreathAway]

Had to take a nap. I switched my cycle sensitivity back to Medium (from Very Low) - I had changed in on Jan 16 and I just realized this may be why I have been feeling more tired recently.

SpO2 and heart rate was incredibly stable during my nap, fingers crossed that switching this back helps.

You're dial-winging. No one here would have ever suggested changing cycle sensitivity. You have already found and passed through the best therapy. Stop making it a pin-ball game. Hopefully, you kept notes so you can help us discourage future members from doing this.

Hopefully, you kept notes so you can help us discourage future members from doing this.

I sure have...  I know given my numbers people assume I am already perfectly dialed in, but I would disagree with that, given I still have (albeit much less frequent) days on which I need an afternoon nap despite always sleeping 7h+.

Regarding the change to cycle sensitivity - I was trying to fix a problem w/ a reasonable approach (imo). Here is what I shared on this thread when I made the change:

Since this led to leaks around my nose, I tightened my straps. The tighter straps made me feel like there was somehow less air/pressure coming (huh?!) and it felt like my breaths were cut off short.

I changed my "Cycle Sensitivity" setting to "Very low" in hopes of fixing this. The flow still felt lower, but my breaths were not cut off anymore.

Since then I have re-adjusted my straps again, which I think helped a bit and I am waiting for my F20 mask, which has a design that won't collapse on itself over my nose when strongly tightened.

I had a pretty perfect night tonight. Still woke up four times from tickles, but that is much better than usual and my nose remained clear from the Nasonex, which is what I think helped me sustain a high SpO2 level w/ zero drops (this has only happened on 1-2 nights before). 

Numbers include the nap I took in the afternoon:

Had a couple good nights on 2x 2 sprays of Nasonex, but started getting a headache, so yesterday I switched to 2x 1 spray and my nose clogged up fully again. I also realized that for a couple of days now my nose has always been clogged on the right side only, whereas before that it would clog on both sides somewhat randomly, which is making me wonder if I may have an infection or polyps.

No more Nasonex: The Nasonex may have helped me a tiny bit, but I had to stop Nasonex completely now after noticing it made me extremely forgetful, similar to what I had experienced in the past before CPAP (which I am now realizing was maybe from the Flonase back then that I used to try to sleep better...)

Humidifcation instead: Instead I tried humidification tonight (auto heat, auto humidity) and it was weird:

Not getting enough air: Similar to last time (post #59) I tried humidification, I immediately felt like there is less pressure coming at me. Not sure if this is real or perception from the humidity or heated hose. I woke up multiple times later in the night feeling extremely out of breath, feeling like I am not getting enough/any air. Looks like my oxygen dipped only a little to 92%/93% during those times. At 3:45 I gave up and decided up the PS from 5.0 to 8.0 in hope that this would let me sleep better. With PS at 8.0, the machine felt the ~same as it had felt w/ PS 5.0 and no humidification. It looks like this initially shot my breathing into a feedback loop, which then stabilized 15-20 minutes later and I was able to mostly sleep through after this adjustment. My respiration rate actually continued to fluctuate fairly widely the entire rest of the night, but no full on CAs. Surprisingly, while I felt extremely tired when this happened during the night, I don't feel that bad at all now in the morning.

JK, ended up being pretty tired after all and had to take a nap after lunch. The nap was pretty good. As I turned around to my left side, I again felt like I wasn't getting enough air, but I just stood up at that point since I had already napped for an hour at that point.

Hey everyone,

Thins have taken a bit of a negative turn for me and I feel much more tired recently.

I have noticed that I have segments during my sleep right now that look like mini-CAs, here's two from tonight:




Here's the full plot for last night:



And here is one overview plot showing things have gotten worse:



Here's a timeline: 
1. Flonase/Nasonex: Feb 2 - Feb 16
2. F20 instead of F30i: Feb 11 - now
3. Increased EPAP, going from 9 to 10: Feb 16 - now
4. Added humidifier and increased IPAP from 15 to 18: Feb 18 - now
5. Azelastine: Feb 26 - March 2

From that it seems like the strongest correlation is with the humidifier and increased IPAP (#4), but for some reason things were good on Feb 21, even though I didn't change anything, which seems weird.

I had my appointment at the pulmonology lab, can someone help me interpret the test results?

It looks like my FRC and ERV are particularly low.

[Jay51]

My Pulmonologist and RT interpreted my pulmonary function tests (so I didn't learn how to interpret them).  Here is the best link I have found:

https://hospitalmedicaldirector.com/how-...ion-tests/     (have to copy and paste this in address bar)

I will try to look this over also to help you out YouTakeMyBreathAway.

[Jay51]

The main test (FEV1/FVC%) looks good (or slightly mild based on the brand new criteria for evaluating this in the above article).  From what I just read, low FRC and ERV may indicate restrictive lung disease or even obstructive disease.  Pulmonologist would give a complete interpretation.  

Have you ever smoked?  Any medical history that may indicate restrictive lung disease or obstructive or equivalent?
