Any chance you're taking some medication that keeps you from deep sleep? Lots of OTC ones will do that.
Nope, maybe I had an off day, or the low pressure kept me up. It felt like I never even fell asleep

So your AHI was the same (1.5) regardless of full therapy (4cm-20cm auto-titrating) or minimal therapy (4cm constant).

How do you feel with no therapy (no device at all) ?

Recall that a AHI of less than 5 is considered "normal" for the population.

BTW, what was your AHI on your sleep study that was used to prescribe your device? (Looking for # of OAs, CAs, Hs and also Oxygen desaturation over x# hours). How long have you been on Pap therapy?

While doctors and insurance may call 5 'normal', it's actually quite terrible.

Just do the math.

The change to fixed 4 cm could have resulted in the body simply not adjusting well to the new pressure since it couldn't go up. The brain/body is kinda funny in that it doesn't like unexpected things that aren't what it is used to.
So the perception of not sleeping so great could be the brain/body rebelling against the "newness" more than anything else.
I bet you actually slept more than you thought you did and you can zoom in on the flow rate and see if you see much asleep breathing vs arousal/awake breathing to get an idea.

The videos here show how to zoom in and lood for asleep breathing or arousal breathing.
Asleep breathing is very rhythmic and regular....arousal breathing is irregular and fairly easy to spot.

Here's an example I like to use....asleep breathing circled in red...everything else is arousal related breathing.

Several nights ago, I had a rare night where my (untreated) AHI was a shade over 5.
I felt like total dog doo-doo.
I'm sure grateful it is usually around 1 or lower.
Then I feel normal.

I suspect that this is what the Original Poster was looking for..... AHI recorded under untreated conditions.

Perhaps you could explain how you achieved an untreated night. Did your AHI breakout centrals, obstructive and hypopneas ?

Your disagreement that AHIs less than 5 are within the "normal" range and do not dictate intervention is a matter that could be taken up elsewhere. For the time being it does not seem to be pertinent to the OP's question of how he can self-evaluate his specific need for therapy.

I sense a derailment of this thread in the works...another pissing contest forming.
Please don't go there. I am not in the mood.
Stick to OP's question and take the other stuff elsewhere please or risk post removal.

In other words....no arguing about stuff that OP didn't bring up.
No hijacking of this thread.

Fair warning and we all know I only give one.

My AHI was recorded by my Airsense 10 Autoset for her.
It was what my apap did not fully treat--and I WAS "plugged in", all night.
For whatever reason,--congestion, mask fit, etc--I had a crappy night.
But not for the lack of trying. I always try.
There is no excuse for not trying--cpap is the best "try".

Thanks, I just wanted to be sure what you mean by untreated. To me "untreated" means no mask, no pressure at all.
What I think you are saying is that your "untreated" night was a "rare" night in which there were no changes (increase or decrease) in pressure - do I understand that correctly?

Identical settings, time in bed, masked up--all normal-
-just a one-off--all better before and now.
I only brought it up to illustrate how horrible AHI of 5+ can make you feel.

Heard and understood !
BTW, "...the perception of not sleeping so great could be the brain/body rebelling against the "newness" more than anything else..." Important point, Thanks for the reminder.
