EMERGENCY data needs analysis

[Mouchet]

I have an appointment with my sleep doctor on Monday morning. I do not really understand the data.

Can someone look at this data and tell me how I am sleeping.
First I am waking up 3-4 times, I did snore, I had two major leaks, and it appears my machine shut off as well.

1. Should I turn off the auto on/off feature. My AHI did not happen during the leaks but around 6-7, and I am very certain I turned the machine on.

2. Can someone look at the first chart and explain why so many AHI and why pressure suddenly drops? (I attached chart) -->

3. Last can someone look at the other charts and explain what is going on. This is a typical night for me now.

Last, I cannot seem to shrink the appearance menu to remove the pie chart, and I am just using screenshots. Is there a program I need to download to better show data. I went to imgur but could not find download button/upload button.

So sorry I meant I need this chart explained

Time at pressure

Pie chart can be turned off...
Preferences/Appearance tab...remove the check mark for "show pie chart".

Please review this thread for the format for showing the graphs and which graphs to show

From what you do show above I see no reason for the machine to have shut itself off..it certainly wasn't during the time of large leak where the machine might have thought you weren't attached...and besides...it takes a lot bigger leak than you have for the leak to cause the machine to turn off.

Pressures change with the auto adjusting machines because of a combination of several factors involved with the auto adjusting algorithm...the OAs, hyponeas are a factor along with any snores or Flow Limitations.

The small cluster of OAs and the pressure increase...the minimum pressure is the most critical pressure setting. It needs to be high enough to hold the airway open in general well enough to prevent the airway collapse but get to higher pressures quickly enough to prevent the outliers where you need more pressure for some reason or other (maybe REM sleep or maybe on your back).
None of these machines will increase the pressure during an apnea event...they wait until it is over and then re-evaluate things.

Due to the timing of that cluster between 6 and 7...I suspect REM stage sleep pressure needs are greater than what your machine can do with the current minimum. I have this myself. My OSA is worse in REM and sometimes I need a lot more pressure in REM so I have to give the machine a better head start with a little more minimum than what might work at other parts of the night.

Your snippets of graphs...makes it really hard to evaluate well and you have included stuff not needed and omitted stuff that is needed.
You can get all you need on one screen shot. The graphs can be resized and moved around.

In general...I think you need just a little more minimum pressure than what you are using now.

The time at pressure thing. Not particularly useful. That particular data value was a work in progress and is incomplete...I suggest ignoring it.

AHI graph...again not particularly useful...it just shows a per hour graph and resets with each hour. We can easily see the when there was a cluster of events happen.

Yeah I am having real trouble with all the computer stuff.

I am using a old computer and cannot seem to move the window to click OK On the preferences tab. I know to click off the pie chart and the order, but I cannot move the window down or up enough.

It is a hp Mini using windows 7 32 mini.

I am also struggling to figure out how to use imgur- that is my data is now in jpeg form and it is on imgur, but how do i get it on my link.
Last,
I m a little confused on what your requesting... Are you suggesting that I move the low pressure or value from my minimum to a higher number?

[Pugsy]

Are you suggesting that I move the low pressure or value from my minimum to a higher number?

Yes, Assuming your were asleep when that rather ugly cluster happened between 6 and 7 AM...just a little more minimum pressure. I would try 1 cm more...no other changes because I don't like making more than 1 change at a time unless there is an urgent need.

There are 2 main culprits when we see clusters where the pressure needs aren't optimal during part of the night and obviously fine for other parts of the night...either sleeping on our backs or REM stage sleep. Both of which it is common for our OSA to be worse and/or need more pressure.
Those wee hours of the morning before we get up is when we typically have more REM..comes on more frequently and lasts a bit longer.
Google "sleep stages" and look at the normal hypnograms and see what I mean.
The timing of the cluster and the duration of the cluster makes me think REM might be the culprit. No way to know for sure unless you video your sleep and see if you were on your back or not. Even if it is supine sleeping related...the fix is still the same..a little more minimum pressure.

If I was seeing on my reports what you are seeing....I would do a little more minimum and in fact some years ago I did just that. My OSA is worse in REM and I often would see some rather marked differences in pressure needs in what would be the normal time I might expect to be in REM.

And no...we can't tell for sure the sleep stages with this data but you can get a very close approximation by learning when REM usually happens. These machines have no way to tell us sleep stages or even if we are asleep or not.

Now if you were for sure awake during that ugly cluster...you ignore it. Awake events simply don't count.

Thank you... I do remember having a vivid dream at this time, and Bible most likely change my setting one up .

Ivana answer bro depressed for many years and I do get very little rem sleep now though. As a matter of fact I keep waking up when I start room sleep according to another program called sleep cycle

[Mouchet]

I meant to say that I am on antidepressants for a long time , And I keep waking up almost immediately after going into rem sleep.

Could this be restless leg syndrome or any other solutions?

[Pugsy]

Google whatever anti depressant you are on...most of them have some pretty negative side effects in terms of sleep.
Often cause insomnia (sleep onset or sleep maintenance) and some even mess with the sleep stages themselves.

Now waking after REM sleep..that's actually normal. If you google "sleep stages" and look at the hypnograms most will show a very brief awakening after REM. Most of the time we don't remember it. The awakening has to last long enough for us to form a memory and most of the time we roll over and go back to sleep and don't remember it.

Also...don't assume that if you remember a dream that you were in REM. We can actually dream in any sleep stage...not limited to REM stage.
To remember a dream we have to wake up during or right at the end of it enough to form a memory.
Remembering a lot of dreams actually means poor sleep quality because it means we woke up often.

You were right raised pressure and got thru 6-730 without waking- phone shows deep sleep at this time for whole week
