Can I get a SleepyHead analysis? Paging DeltaDave

[JaxTom]

Love to hear what every one sees on these. My story: Had CPAP for years set at 12. Did nothing, stopped using it. Got new titration study, doc decided I needed BiPap 16/12 pressure. Have had my machine for a month using it every night. Been playing with different mask, chinstrap combos. Last week I have been on Dreamweaver Advance, no chinstrap. Doc saw some centrals during titration and said we'd go bipap for a while and see if they go away.

The one thing that jumps out to me is about 75% of the time I get clusters of events in the morning before I wake up. Last night screenshot is pretty representative.

The other thing I wonder about is that I am on a set 16/12 on a machine that can auto adjust........

Edit: See messages below for images

JaxTom,

I tried clicking on the link, but it requires a Google docs login, which I don't have. If you've save the chart as a .jpg file, you can up load it to a site like photobucket and embed the link in between an [img] and [/img] pair.

I could see the linked image. Let me try to bring it over here.

I only see one page with three graphs - hard to tell?

Can you take another screen shot with these graphs: flow rate(events), mask pressure, and leaks?

I typically put my photos on something like imgur.com and link them inside [ i m g ] tags (remove spaces)

[Pugsy]

SleepyHead graphs can be resized so that we can get more graphs in one image. Hover your mouse over the bottom line of a graph until you see a short double line then click and drag upwards just a little. If you do it with each graph then it will let you show 4 or 5 graphs in one image. Doesn't harm the ability to evaluate the graphs either.
I like to see the top events graph so that the overall night is easily seen, the flow rate graph, pressure graph if using auto adjusting pressures (if straight pressure no need because it doesn't change), the leak graph and maybe snores or flow limitations if they show much of anything.

This link is for my ugly leak line night. You can see how I have changed the sizes of the graphs so the main ones are showing. You can also turn off the pie chart (in preferences) and that brings the rest of the numbers up into viewing area.

I don't know what to make of your report above. In addition to showing the top events graph could you zoom in so the really tight CA cluster that appears to start just prior to 5:30 and the obstructive cluster right around 6:30 are zoomed in way closer so we can see the individual breaths? You won't be able to get the whole cluster.
Something along these lines.

[JaxTom]

OK let's try again. I signed up for imgur.com

I'll try also for close up of the cluster.

[JaxTom]

Here's one with summary graphs off and a close up on one of the clusters

[Pugsy]

Can you zoom back out just a little and can you include the top events graph? At this zoomed in level there is no real need for Respiratory rate graph. Put the events flag graph on top of the flow rate graph.

[JaxTom]

How's this

[Pugsy]

That's better can you get a similar image of the obstructive cluster?
Do you remember waking at all during this 2 hour time frame?
I am not the greatest at evaluating flow at this level....so calling DeltaDave and asking for his input....DeltaDave...can you offer some thoughts please?

[JaxTom]

Don't think I was awake. Here's a obstructive cluster

[Pugsy]

Okay, thanks. Now let's hope DeltaDave will see it. Maybe add his name to your topic title?
Couple more questions. In your sleep studies did they mention anything about REM sleep being worse or sleeping on your back being worse? Do you have copies of your sleep studies? Did you have centrals mentioned during the diagnostic portion of your sleep study (no machine)? Do you sleep on your back some of the time or none of the time or all the time?

What I find odd is that for the bulk of the night things went along quite well and it only goes to hell the last 2 hours of the night. So it appears that something changed to cause it. What? I have no idea. If you reported that you remembered waking up then we might blame that ugliness on awake/semi awake sleep transition stuff. It still might be that and you simply don't remember it but I am not the greatest at evaluating the flow. DeltaDave is though. He would have a better idea if what we see close up is asleep breathing or maybe awake/semi awake breathing and/or is this pattern a CSR pattern.

So I can't do much more than ask questions and wonder myself. I was just trying to maybe get images so that DeltaDave could see what he needs to see and have some questions answered that might help clarify things.
It really bugs me that only the last 2 hours are so ugly.

[JaxTom]

When I had no machine I had no centrals. They first showed up under "the mask". Doc thinks they might go away. They did say I was worse during REM I believe. They said my 16/12 pressure knocked it out, but they stopped the study around 4, and it seems these clusters always show up later. Starting about 5. Makes me wonder if the machine was set to adjust if it might adjust during these times that it might fix these.

I am assuming that when you say they stopped the study at 4 that you meant 4 AM and since you typically have this mess at around 5 to 5:30 AM they may have missed it???
Another question...do you typically sleep through the night without any wake ups that you remember?

If you had the auto adjusting machine it might fix the obstructives but it wouldn't do a thing for the centrals and if pressure is the trigger then higher pressure to maybe address the obstructives could maybe make the centrals worse. Might trade one event category for the other.

Have you seen the Complex Sleep Apnea video? I am not saying that is what you have going on here but it is very suspicious.

How is it possible that the Min, Mediane, 95%, and Max of IPAP or EPAP are the same number (in the Statistics)? And also the Mode is at APAP 0-0 cm?
