can someone read my oscar chart and tell me if it's good or bad?

I managed to sleep a long time with the device. Went to bed at 10, woke up around 4.00 at midnight and had to check, my AHI was around 4.5 of which 2.8 central and 1.7 OSA which is great if you ask me. Sometimes i slept for like, 30 minutes without any registered apnea event.

However i had to get out of bed to go to the bathroom around 4 at midnight and cause my lower back hurts cause i slept in a wrong position, but after i fell asleep again it seems like my CSA went skyhigh and i had so many many, many central events. is it possible that i slept like sh*t because of my lower back pain and causing these central events or something?

How is this possible? for the first 6 or so hours my chart looks fine-ish but after i woke up and went to sleep again my breathing was all over the place, it doesn't make any sense. 

for the first 6 hours the chart looks so much better than any other night if you ask me, after that it all went to crap for some weird reason.
all i did last night was take a 0,3mg time release melatonine but i doubt this had something to do with it.

Ps, i changed the pressure from 5 to 5.6 last night due to the OSA events i had the other nights and that seems to work just fine in lowering OSA

I used to have lots of back pain, and woke me up also.

Concerning the detail flow of one event, I find it really difficult to tell if it is actually a true central, or an obstructive.

This is because you are on a fixed pressure. Normally if you are on APAP, if it is an obstructive, you see a pressure bump as the algorithm detects the obstruction.

For a central event, there is no obstruction being detected, so no pressure change,  as literally is is a "clear airways"  path.

I have attached a couple of my examples, one of an obstructive event, and one of a central, showing what I think is the difference.

This is my personal interpretation only, I add of course I am not a professional, so could be totally wrong.

If I am right, then the question arises, what about all the other "centrals". Are they really mainly obstructives?

Should the APAP route be tried, initially with a basic titration, then once we have an idea of the approximate range of pressures, thn optimise?

These are rhetorical questions, others may have a much better interpretation.

well since the sleep study said most events are central, i guess i can assume that most of them are central on the central chart.
But you talk a lot about obstructive apea which is barely the case for me, it's mostly central.

what i dont understand is why there were so many centrals after i woke up and went back to sleep with back pain?

this is actually my question, what could be the reason why there was a peak in CSA events after i went back to sleep wtih back pain?

Sorry for the double post, why can't i edit my previous post anymore? 

to simplify what i mean i posted 2 screenshots of Oscar AHI chart. i think i fell asleep around 22:25 as that's when the first apnea event happened.

for the first +/- 5 hours i had events that were kinda spread in those 5 hours which gives me a total of 17 CSA events and 9 OSA events. 

from 4.45 midnight until 7.20 in the morning (2 hours and 25 min time) i had 36! central events which was more than double of what i had the first 5 hours and were almost all a few minutes after eachohter. 

What my question is: what could be the cause of this? it can't be OSA events that the device detects as CSA because i barely have OSA events these days and it wouldn't make sense either.

Sorry, I really don't  know the answer to your main question, it could be due to your therapy environment, having continual arousals resulting from the effect of incessant events during the night. 

That's as far as I just can't tell from your recent zoomed graphs, for the reasons I indicated in my last post.
 
I could speculate further on other possibilities, but I believe it would be inappropriate. 

That's all I have unfortunately.

To answer the Central Apnea question, I think from the beginning of this thread your Central Apnea was an issue. It showed in your sleep study, according to you. You're still on a ResMed AutoSet I think, because we cannot see the left panel in OSCAR now.

If correct, the AutoSet cannot treat Central Apnea. You can see it works well with Obstructive, not at all with CA.

Central Apnea have a unique random trait, consistently inconsistent. There will be times the CA are few, then a lot, then none. All with no edits to therapy settings, on machines that cannot treat CA. Like yours.

As the CA are a big hindrance to you, you'll need to get a ResMed Lumis ASV. This alone treats CA properly.

I didnt post the left panel today, i did that the other x days. Im on cpap but i never had so many csa events in such short time frame. In 5 hours my CSA AHI was only about 2.5 which was great so i think cpap does help, but after waking up and going back to sleep with back pain my CSA events increased dramatically.

If i can only manage to get my OSA down to 0 then it only leaves my CSA AHI of about 2.5 which is just fine by me..... right?

Zero events in any category shouldn't be required. As low as possible consistently and with good, comfortable sleep.
