Please review my SH chart for any suggestions

Thank you in advance.....Janice

I'm a newbie, but looking at your graphs you had a leak at about midnight, it was short, the machine responded... all looks good. However, get the opinion of some wiser heads on this site.

Did you take your mask off for 20 minutes just before 1 AM...Looks that way to me. That's the only spike all night.

jwerley,

Where's the AHI graph or the flow wave? Those are just as important as the leak graph.

As far as the leaks go: Keep in mind that the total range in the y-direction is 10 L/min. In other words, you had one roughly twenty minute middle-sized leak of about 10 L/min and one small-sized leak of about 2 to 4 L/min. Your leaks are just fine and dandy if this is a typical night.

And why do I say that? You have a grand total of about 40 minutes of detectible leaks for the entire night AND the absolute worst of those leaks lies well below the Resmed Red Line at 24 L/min.

According to Resmed, the Resmed machines can compensate for leaks up to the 24 L/min range and the Resmed engineers believe large leaks are only problematic only when you are leaking at at rate AT or ABOVE 24 L/min for at least 30% of the entire night. You had the machine running for 6 hours and 24 minutes, which is equal to 6.4 hours. And how much is 30% of 6.4 hours? Well 30% of one hour is eighteen minutes, so 30% of 6.4 hours is 115.2 minutes. And that's 1 hour and 55 minutes of large leaks.

Find something else to worry about than your leaks.

Next time....omit the snore graph and the respiration graph...instead scroll up so that the top event graph is shown..that is the one above the flow graph.
Best to show the events graph, flow graph, pressure graph, leak graph.
Leaks? I wish my leak line looked as good as yours.

Are you resting better? Feeling any better than you were?

LSAT,

You need to look at the vertical scale on a graph (any graph) in order to make sense of it. SleepyHead displays the leak data with a y-scale that "fits" the data and shows every single small bump in great, magnified glory. In this data, the maximum y-value in the leak graph is a modest 10 L/min. Hence, that 20 minute mid-sized leak just before 1 AM looks like a large mountain instead of a rather modest mid-sized hill. The top of that peak is less than half the way up to the Red Line in Rescan.

If jwerley had taken the mask off but left the machine running for 20 minutes, the leak would have been much, much larger---as in 60-100 L/min range since the Resmed machines subtract off the intentional leak rate.

I did not take my mask off all night....and since I don't know how to scroll and take a picture at the same time...there is a continuaton of my sleep chart posted....I slept all the way through the night...
Thank you all for responding....I was thinking that since my pressure goes right up to 15, where I have it set... that maybe I should raise it to 16...but I don't know.....

[jwerley]

Yes Pugsy I am feeling better...I thought I had the first part of my graph posted as a continuation...but I lost it...I don't know how to take a pic of more than just a page at a time...In other words I would have like to have posted the whole thing...I will have to figure out how to do that...Thank you for asking and for caring!! Janice

There is no need to take more than one picture...just have to make sure that what you see on the screen shot is all that is needed.. You had scrolled down a bit and that took the events and flow graph off the page.
Just position the graphs so that the images so and then do the screen shot. Here is one of my examples.

My guess is that your apnea is primarily REM-related, given the time of the night when your pressure/leak rises. It's very possible that you are opening your mouth in REM, causing the leak

Were you talking about my leaky report?
Yes, I am documented primarily REM OSA but the report above...just used it as an example for graph selection..that leak and cluster of events right at REM time...I was totally awake for that period of time..laying there trying to decide if I needed to get up and go throw up...extreme nausea..lots of mouth breathing trying to spell the nausea and lots of tossing and turning...I was totally awake during that time.

Now that little 4 AM spikey leak.....I might have been mouth breathing then or the nasal pillow may have moved.
