My first data download

[Lizistired]

Vulcan, I'm not sure if you have found this yet. Right under the "device log" tab, there is an icon with a graph and a check mark. When you click this, you can select which graphs you want to see and how many to show in both the Navigation(top window) and the Detailed(bottom window). Make sure the "flow" is checked. I usually uncheck the AHI and Snore Index, since I don't snore so they don't tell be much.
The scale to the left of the graphs can be adjusted if you hover over them and then click and hold to drag them up or down.
The clinician's manual for ResScan should be here on your computer:
"C:\Program Files\ResMed\ResScan3\ResScan Clinician's Manual.pdf"

Ok, first time try at posting results... and I have no clue how to post the graphs from resscan. I created a report and it opened it in a pdf file 3 pages. I selected an image and saved it but I don't know where resScan saved it to or how to insert it into my post. What would it have named it?

After you got a Report and click on Save, it first asks you to name it. I enter the date with the name. It then saves it in the Browser column on the bottom on the left. But it's still in PDF. Since there is no one on this forum who can explain graphs reliably I deal only with the Statistics which is in text. To show it here I click on the saved PDF and get it ready to be copied to here by pasting it.

And we are to take your word as the gospel? Why?
It's not rocket science and most of the time common sense will often give us very simple answers. Big leak? Wow, think that might impact therapy which will then impact data? Your own data points to higher than accepted treated norm AHI values and your leak numbers point to large leak for a good bit of the time. I don't need to see your graphs to figure out that correlation.

But hey, I know I am not one of those 2 or 3 that you deem able to comment on your numbers and likely won't even see my comments but I don't care. When you spout off misleading information to newbies you can count on it being challenged whether you see it or not.

I know avi123 won't see my post either since I've challenged him before when he's in error and thus he's written me off........but IF we are all so truly dumb, why would he keep hanging out here?

LOL, didn't mean to start a war here. Really the data is pretty simple. Just have to learn what it means, learn how to use the software and common sense takes over. I will download last night and see what it shows, I tightened up the headgear a little.

Here is last night. Am I correct in assuming the lower beneath the red horizontal line the better for leakage?

You didn't start the war. This has been going on for a little while on other fronts.
Yes, just a little common sense but some people don't seem to realize that and make more of it than is necessary.

Work on the leak. Mask and leaks are the hardest things to tame. Last half of the night looks great though.

I edited mt post and included last night. Please check it out above.

Thanks

You are correct. Stay way below the red line. ResMed machines already subtract the intentional vent/leak rate for masks so any leak reported is excess leak. Anything above the zero line is excess leak. The red line is at 24 L/min where ResMed says it can't handle the leaks and most likely will impact therapy and data.

Until leaks are well managed we can't put a huge amount of faith in the other data. Nor can we expect to be having effective therapy and feel better. So work on the leaks.

Common source of leaks? Mouth.... Are you still using the nasal pillow mask and living mouth "open"? Dry mouth, snores....That leak might be mouth breathing or mouth relaxing and dropping open when asleep. If you think this may be possible you may have to try something to keep mouth closed. Tape, chin strap, etc or consider full face mask.

If not mouth then the pillows are sliding out a lot, try a different size pillow and see if that helps or seriously adjust the headgear.

Okay, that's what I thought but... this has me a little concerned, although it may be nothing. Maybe everyone has one or two centrals a night. I assume the "flow" graph is measuring my actual breathing. It looks like I stopped on that one event. Probably nothing with only a couple a night. Looks to me like it has nothing to do with leakage.



Thanks

My machine does not give me Flow like yours does. It also does not give me central events. I could very well be having a couple of those a night and not know it. I am not familiar with flow patterns other than what I see here on the board.

The machine won't respond to what it deems to be a central and the leak or lack of leak may not even factor in. Maybe someone else could clarify possible relationship between leak and a central and the appearance on the Flow graph.

Of course you stopped breathing! That's the definition of apnea. Yes, the flow graph is showing your breathing pattern. You can't say it has nothing to do with leakage because the connection between the two is not overtly visible that I've ever been able to see. I can tell you though, based on my own graphs, a higher leak rate does cause a lower flow rate. How much that lower flow rate affects the incidence of apneas isn't clear I don't think. But until you have leakage down to a small number seeing the results of future pressure adjustments is probably near hopeless.

The problem is this entire therapy can be so nebulous at the finer levels of adjustments that any excessive variable thrown in by such things as uncontrolled (as we see it!) leakage makes it nigh impossible to separate cause from effect.

I believe it would fair to say that there are two approaches to xPAP therapy, achieving gross results, and seeking fine results. The primary goal of the sleep doctor is, for most patients, to achieve gross results in that bringing AHI numbers down from dozens to less than 5 is success. Many of us on this forum, for whatever personal reason, seek the fine results of bringing our AHI down from the 3, 4, and 5 range to less than 1, and ideally down to zero. To achieve the fine results we shoot to control leakage down to zero if possible. Are we obsessed? Probably! That's why we harp on the leak rate! Is there any long term benefit for being obsessed? We hope so but I doubt anyone has definitive info saying there is or isn't. Only you can decide for yourself how far down this road you want to go, and if your apneas are under control to the point your doc and you are happy who are we to say you must do better?

Here is the data from my first night with an improvised chin strap to keep my mouth closed at night. Hoping to fix leakage problem.



Looks like quite an improvement.

Looks pretty darn good to me! That graph is much like what I see most nights for myself, which is one reason why I think it really looks good!! And I tape my mouth!

Very good. I think you have it figured out now. Good job.
