Is it possible to draw conclusions...

[tedburnsIII]

Is it possible to draw any reasonably accurate conclusions as to SLEEP STAGES, etc., solely from the charts and graphs below? If so, what would be your interpretation?
PMs okay if prefer not to post here.

Thanks in advance.

I think it is possible to guess, but I don't think it is possible to be reasonably accurate using any measuring device that doesn't measure brain activity.

Thanks for your comment, Nick.

Without inquiring as to what particular sleep stage is represented, could you say the different levels do represent sleep stages, or some change in sleep stages, or would your answer be the same? IOW, the changes in SpO2 that look a bit like a hypnogram, can those only be equated as changes in SpO2, and one should not infer anything else?

Thanks in advance.

Further comments appreciated.

Brain activity . . .

[Nick Danger]

Without information regarding brain activity, I don't think we even know for sure that you were asleep - much less what stage you were in. We sometimes guess that clusters of events are related to REM sleep or sleeping on your back, but even there, we're just guessing.

Interesting. Thank you for your comments.

Right here, and FWIW, found this during a Google search on the topic:

p.s. The Zeo is apparently out of business, but take thread FWIW.

You're still doing it - telling us what we can do - we're not staff. And will PM if we want to (or not).

p.p.s. doesn't keep people from using them, as anybody that READS stuff here would know.

Julie, he was saying it was okay to PM him if one preferred. I don't know why you bother to read his threads or respond in them. He seems to piss you off. And for the record, I'm not trying to tell you what to do or not to do, only pointing out the obvious

[Julie]

Yes, he PO's me - I don't need someone to tell me I can PM if I want to... The thing is, if he wasn't 'him', or another newbie, I would ignore that, but coming from him, with his history of that kind of thing, I don't. Sorry if it bothers you... not meant to upset anyone else.

The only that that made me comment was that you seem so upset about it. I guess I was just saying it isn't worth getting worked up by someone you don't even know. You seem like a nice person and are very helpful. I also think Mr. Burns seems nice enough. Personalities sometimes clash though. Nothing says either of you need to interact. I'd rather see you happy

[Julie]

Thank you, that's the nicest thing anyone's said in a long time . I think you may have missed some of 'his' stuff on the way here - I don't recommend that you go look for it, but he truly isn't a nice guy (and I haven't been alone in thinking so), for all that this thread seems innocent. And sometimes I just sound off when maybe I could not do so... but you know all kinds of evil people (and I'm not suggesting he's evil of course) have been 'nice' to lots of people, and kids, and dogs at some time... think I'll just leave this here. But thanks again.. it's definitely good to know there are people like you here!

As others have said: Without data about your brain waves, there is no way to accurately determine the sleep stages.

With flow rate data, which is a trace of every breath you take all night long, we can sometimes make a pretty good guess as to when sleep onset is and when some arousals/wakes may have occurred. This is based on the fact that normal sleep breathing "looks" different than normal wake breathing. But your machine does not seem to record the flow rate data, or if it does, the software provided by your machine's manufacturer does not show that data.

If there are significant clusters of events that start about every 90 minutes, we can make an educated guess that the clusters might be REM-related. But in the data you posted, there were only 3 H's recorded during the 24 hours. One in your nap and two widely space Hs during the night. So there is no clustering of the events to look at and we can't make an educated guess about when you may have been in REM that way either.

I am NOT an expert on reading Sp02 charts. I don't have an oxymeter of my own and so I've not had much motivation to learn how to really read these charts.

But I will say this in as a mathematician who knows how to look at graphical data: It is not clear from the Sp02 chart what time = 00 means in the context of the CPAP data. In other words, it appears that on the Sp02 chart, time = 00 represents the time the sensor is put on the finger and turned on. But without knowing what time you did that, it's impossible to correlate the data in the Sp02 chart to the data in the CPAP data.

And even if we make the assumption that you turned on the CPAP and the oxymeter at very close to the same time, there's still the problem that the horizontal scales on the CPAP graphs and the SpO2 graphs are not the same. And that makes it difficult to figure out which part of the graphs "line up" and cover the same part of the night.

And hence it's very difficult, if not impossible, to determine whether the SpO2 events recorded by the oxymeter have any relationship at all to either the 3 Hs recorded by the CPAP or any of the pressure increases recorded by the CPAP.

Julie- you are an absolute 'thread-crapper' and not worth my time of day! Leave me alone. You are so full of it. I only suggested that a person PM me as an alternative to publicly stating an opinion that might prove to be embarrassing or erroneous. Yikes! See a shrink, please! And you and the rest of your 'cohorts' might consider some 'group therapy' of the internet kind, if such thing exists.

Stop wasting my time and that of everyone else in this thread! Please!!!
