Myencore leak graph

Hi,

I'm a little confused by the Myencore leak table graph. On the MyEncore shows my maximum leak rate at over 100 l/m whereas the Encore pro graph for that day doesn't show anything near that high.

I've included the images so hopefully someone can explain what i'm looking at.

Thanks
Liz

There is a spike at the end of your encore pro graph where I assume you took your mask off at the end of the night before shutting off the machine.

Although it doesn't appear that high, I assume it is what my encore is detecting. There is a limit on pixel interface, and there are math round off errors in any of these programs when data is manipulated and graphed.

If you actually have your mask off during the night for a few minutes you will see a LL on the graph.

I would say from your average leaks you don't have a leak issue. I get leaks in mid-20's with swift and pressure of 9.

Hi Liz,

I know what you mean. I have discrepancies in the numbers between Encore Pro and MyEncore......some in the areas you mentioned.
Example: Encore Pro will report an average leak rate of about 36 and MyEncore will report the same nite's average at 40 or 41. Also, the same thing you mentioned with "max leaks". I may have had no "max leaks" in Encore Pro, but MyEncore will show similar numbers to what you're showing on your chart (over 100) or wild swings with no numbers to reflect that in Encore Pro.

I'm just kind of taking it all with a "grain of salt". I don't get too excited unless things start showing a "trend" over a number of days (like it did in the middle of January....but then settled back down after about a week). As long as I'm feeling good, I believe that's what matters.

Don't know if this eases your mind, but I can relate to what you're seeing.

Best wishes,

Den

You may be right there I do take my mask off before turning off the machine. I'll do a little test tonight to see if it changes the max leak.

Thanks

I'm not "buying" these arguments....in my case. For one thing, I always shut off the machine before taking my mask off. The other situation is that the "average" leaks don't agree between the two software packages.....by several points. As far as "rounding" is concerned, Encore Pro rounds UP on AHI numbers....a lot more than MyEncore.

Encore Pro doesn't show me any leak graph, I don't think. How do I get one? Is it only used on AutoPAP models?

Once in the patient record double click on the "sleep therapy compliance download for the data you are interested in and select full details. You will then need to go to the page for the day you are interested in. At least that's what I do for my autopap as I have just found out.

Thanks - I found it.
Now, if I may continue to be a real newbie: how do I attach a graphic to a posting here?

As I write this, I see at the left of my screen that HTML is off.

Doug,

First you have to put the graphic on a server somewhere because this site will not host the graphics. Most ISP's provide a small amount of server space for you to have a web page. There are also places that offer a small amount of web space for free. After you've uploaded your file to a server then you use the Img button when you compose your post to link to your graphic file.

Of course, if you've never uploaded files to a server before, then there's a whole other set of issues to deal with first.

I feel just like the kid in class who knows the answer and is saying "pick me, pick me". (OK, so I really stole that line from Shrek, but nevertheless it applies.)

It would be way to easy to just blurt out the answer, so I'll first show the charts. Here's the MyEncore graph of my first night with my replacement Remstar Auto.

Notice that the max leak, average leak and 90% leak pressures for the night of February 22 are all very close to the same high value of 150.

Now, here are the Encore Pro charts for the night in question.



Notice that Encore Pro reports a relatively low leak for the entire night. The ONLY way that this can happen is if the constant large leak is subtracted out. Respironics is proud of the fact that their algorithm does exactly that very thing.

There is one other important piece of evidence that doesn't show up in the charts that, I believe, conclusively proves this: I noticed after getting up that morning that there was a huge amount of air blowing out between the Remstar Auto and the humidifier.

It was amazing to me. It didn't seem to matter at all to the machine that all that air was blowing away (so to speak); the machine kept doing its thing just fine.

Bill

Problem resolved. I made sure to turn off my APAP machine before taking my mask off this morning and my results today show a max of 40 on the myencore graph. I think it couldn't be seen on the Encore Pro graph because I had the machine on for more than 8 hours and the graph only does 8 hours. I would have seen the spike at the end if the graph showed entire working time.

Thanks For the help.

I have another question now. How does the machine know that i'm having an event? Especially snoring since I don't usually snore.

Thanks
Liz

Liz,

You just hit my funny bone when you said "Especially snoring since I don't usually snore." I used to tell that to my DW all the time but never got away with it. I guess we just don't hear ourselves.

Thanks,
