ResMed apnea type CA/OA recognition problem

Where can I read more about these arousals?

great! thank You!

You should be able to see a difference in the corresponding Mask Pressure chart too. they're not huge differences, they're subtle, but they're there.

I know the theory ... but I really do not see the difference on the graph.

I’m having a hard time seeing the difference too, but I’m nowhere near the expert these others are.

I do know the theory that CA is caused by too much pressure, but it can also be the wrong rot or many other things. If there are obstructive mixed in with the centrals, I’m going to assume a lot of things before I assume my machine is making an error with the FOT.

I also think that the reason may be a mistake with FOT. I did not know about it. Central always appeared to me mainly in the morning. Now I have to decide whether to reduce the pressure ... or maybe it should be even greater.

Or, perhaps you should just ignore them. Arousals in the morning and the corresponding CA's attributed to Sleep Wake Junk are NORMAL. SWJ events would not be counted in a lab.

Well, I'm done with trying to help someone who's rolling their eyes at every comment.

I'll leave that to others.

Cheers and good luck.

I was scared when I saw the results that night, it's not easy to ignore. no changes today, we'll see tomorrow.

I'm sorry, I didn't mean to offend you. I probably mistakenly used this emotion. It was supposed to mean that I was wondering about...

If the scale if decreased to enlarge the FOT wave and then The FOT from the Flow rate graph is compared to the corresponding FOT from the Mask Pressure graph, there is usually a phase shift apparent with one type of apnea and not the other. I forget which now.

I checked it out... and you're right! higher flow and phase shift in CA
I didn't know that.

Many people are scared when they CA's. I guess it's something about it being "central" which seemingly implies there is something wrong with the brain, I guess. In reality, most centrals we see here are post arousal and are just the voluntary holding of breath after a movement, or sigh, or deep breath, or the like. Usually nothing to be concerned about.

Given the time of morning yours occurred, I wouldn't doubt you were lying there awake or semi awake and therefore, as previously stated, they don't count.

I need to verify my knowledge. Until now, I have linked my CA's to too high a IPAP pressure, which results in reduced CO2 saturation. I think there's nothing wrong with the brain.

Eyerolls are typically used to convey "what is this stupidity I'm hearing?" or something to that effect.

I generally avoid emoticons because I don't know what they mean.
