Crazy flow rate on OSCAR. Need help interpreting if possible.

I'm having trouble interpreting flow rate graphs that are crazy looking when I.m sleeping. They sometimes are accompanied by flow limitations and sometimes not. Please help.

Do you remember waking often during the night?

Do you take any medications of any kind? If so, what....include OTC if you take those as well.

Could you also post the overall non-zoomed in image of the same night as you did the snippets above.

Please Include these graphs on the right side..
1. Total events flags
2. Flow rate
3. Pressure graph (the regular pressure graph not the mask pressure graph
4. Leak
5. Flow limitations
6...snore graph only if there is much on it

and on the left side
AHI and not the RDI
along with the other stuff you included above

So it looks like this one

Thanks for answering my post. I remember only waking up once during that night which was actually around 5:00 in the morning. I take 75mg of Seroquel; 30mg of Mirtazapine; 600mg of Gabapenten; 3mg time release Melatonin. Believe me it takes alot to get me to sleep through the night. I cannot change the RDI to AHI because it's already been recorded. I look at RDI's because when I was diagnosed with OSA I was at a 5. My RDI's were at 22 total for the evening. download/file.php?mode=view&id=20568

Are you having any nasal congestion during the night?

Can you do another snippet for me?
I would like to see a zoomed in time frame that includes the 2 CA/Centrals at around 3:10 to 3:20 be sure to include about 10 seconds of flow rate right before the 3:10 Central/CA flag.

What caused you to have a sleep study? What were your symptoms? Was it done in a lab/hospital setting or one of those home studies?

Do you remember what was going on from 4:10 to 5:10 and your wake up at that time?

I may need to ask you to use SleepHQ website so that I can zoom in on the flow rate/breathing myself so I don't have to ask you to do a gazillion snippets zoomed it. That website lets you post and image that is interactive and I can zoom in to my hearts content.

The snippets of flow rate you first posted looked like arousal/awake breathing to me....doesn't look like you were sound asleep
Real asleep breathing is very boring and regular and to my eye it doesn't look like you were sound asleep....now you may or may not remember being awakened but it sure doesn't look like sound asleep. Take a look at this snippet of mine below. I circled the for sure asleep breathing in red .....all that other stuff is arousal or maybe awake breathing but I didn't remember an awakening at that time.

same time frame but just zoomed out more

Thanks again, I did not have nasal congestion that night as I have not been congested for a long time. My sleep study was a one night study at home due to chronic middle of the night insomnia and REM Behavioral Disorder. They found that my AHI was 5 for Obstructive Sleep Apnea. For the REM Behavioral Disorder they relied on my wife's reporting which is why I don't sleep in the same bed because of risk. I also have been diagnosed with sick sinus syndrome (heart) and heart murmors which might be a problem with the respiratory bumps that I see every one to three minutes. I was able to show the AHI which was 2.08. I honestly don't remember what was going on between 4:10 and 5:10 that morning as I was vacationing at the coast and in bed with my wife during that time. She said that I didn't wake her up. Here is the section of close up you are looking for: download/file.php?mode=view&id=20570 download/file.php?mode=view&id=20569

That's a little too much zooming in as it doesn't give me a good sense of the respirations.
Having 2 flagged events in one image gives more breaths to look at to hopefully get a better idea as to sleep status.

Can you point exactly to what you are calling "respiratory bumps" that you are concerned about?
I did see what seems to me to be cardioballistic artifacts in some areas of the snippets you first posted and those are fairly common to see sometimes and don't really mean all that much usually.

In general on those snippets it doesn't look nice and regular like we expect sound asleep breathing to look like.
I am scratching my head here.

I guess you need to give me a SleepHQ (same dated report as the Oscar) so I can go and look but I need to know exactly what you are calling "respiratory bumps".

I was able to zoom out the two flags you requested but doesn't give you a good shape of the waves. It does look like I'm awake but I don't remember it. I'm posting a graph where I know I'm asleep at the same zoom level and it will also show the "respiratory bumps" as I call them which look like a large inhale followed immediately by a large exhale. I get those roughly every 1 to 3 minutes throughout the night. I don't know if they are heart related or not.

Pugsy,

This is an excellent example of where the "share profile" feature of OSCAR 2.0 could be very useful--you could zoom in and out on all graphs as much as you wanted to assess what is happening. OP could post just the last day in full OSCAR format. The easiest way requires that the user have a Dropbox or Google Drive account; if not, they have to send you a file. See https://www.apneaboard.com/wiki/index.p ... _OSCAR_2.0 and https://www.apneaboard.com/wiki/index.p ... _a_Profile.
