ResMed Report and Open Mouth Sleeping
#1
Hi All
I use a ResMed S9 machine and usually look at the "last night" report on the Info button every morning. It's a pretty simple report, but what I'm wondering is whether the "mask fit" smiley face indicates whether I'm keeping with my mouth closed when I'm asleep.

If not, is there any way I can tell if my mouth is open or closed?

Thanks in advance!

Leak rate and/or dry mouth is your first clue - open mouth (mouth breathing) will show as a leak - the problem is the frowny face only shows during bad leaks.

Thanks for that Peter. I'm a new CPAP machine user (about 2 months); can you tell me how to find out my leak rate? I've certainly had a dry mouth from time to time.

Does the frowny face show only during the event, or will it be there next morning?

s9 report unintentional leak (mask leak plus mouth leak), mask-fit indicates good if 70th percentile leak less than 24 l/m
chinstrap helps keep mouth closed and minimize mouth leaks while using nasal mask

1- standard info menu
press the info button for 3 seconds to get into sleep quality report. you should see usage, mask fit icon (smiley or frawny), and ahi (frawny face means leak rate was at or above 24 l/m for at least 30% of the night). if only usage displayed means someone locked you out of the sleep report data. to unlock it, you need to get into the clinical menu and change sleep quality to on instead usage
cpap day start from noon to noon and at noon reset to zero. if you checking the data after mid-day, go to advanced info menu

2- advanced info menu
press and hold the info and setup buttons for three seconds. this gives you additional data and information

Mr. Red Frowny shows up if you are leaking AT or ABOVE 24 L/min for at least 30% of the night. Otherwise Mr. Green Smiley shows up.

Resmed defines an Official Large Leak as any leak over 24 L/min. A few Large Leaks are usually not a problem when it comes to the efficacy of the therapy and the accuracy of the data. But if the leaks are both long and large, they can adversely affect both the quality of the therapy and the accuracy of the data.

Mouth leaks usually are large and are often large enough to be Official Large Leaks. So if you're sleeping with your mouth wide open for 30% or more of the night, then there's a pretty good chance that Mr. Red Frowny will pay you a visit the next morning. But if you're sleeping with your mouth wide open only 25% of the night, there's a pretty good chance Mr. Green Smiley will show up the next morning.

Quote:If not, is there any way I can tell if my mouth is open or closed?
By going into the Detailed Sleep Report on the LCD you will see what's called the 95% leak rate. If the 95% Leak rate is 30 L/min, that means that for 95% of the night your leaks were AT or BELOW 30 L/min and for 5% of the night your leaks were AT or ABOVE 30 L/min.

If the 95% leak rate is below 24 L/min, then you know that there's not enough leaking going on for mouth breathing to be a serious problem.

If Mr. Red Frowny shows up, then you know that there IS enough leaking going on for it to be a problem, and mouth leaks are a top suspect if you're not using a full face mask.

If the 95% leak rate is above 24 L/min, but Mr Green Smiley shows up, you're in grey territory. Some of the leaks are definitely large enough to be a concern, but the question is how long did those leaks last? The only way to really assess this situation is to look at the leak line itself in either ResScan or SleepyHead. If there's a lot of large humps in the leak graph and those humps are often near or above 24 L/min, you're probably doing some mouth breathing. And if you're also dealing with dry mouth symptoms or the AHI seems to be too high, those leaks may be long enough for them to be a problem for you, even if they're not a problem in the Resmed engineers eyes.

Thanks to all of you for the detailed and very helpful replies! Sounds like I have a little research to do. Thanks Zonk for all the help.

Robysue, on the plus side, I have never had Mr. Red Frowny in the morning, so it seems likely I don't have a serious problem. That's good to know.

I'm going to install the software and get to work!

Thanks again to all!

Update:

I got into the Advanced Info as suggested by Zonk, and got the following for the 30-day period:
Leak = 7L/min. and AHI 0.8, total AI 0.6, Central AI 0.0

These numbers seem OK to me, but can folks with more experience than I have comment please?

Thanks again!

Hi brianps, welcome to Apnea Board. Coffee

Just my opinion, but I would love to have those great numbers as a 30-day average. Looks very good to me. Leak rate low, AHI at 0.8 is super.

Congrats

Are you feeling any better now that you've been on CPAP for nearly 2 months?

Thanks SuperSleeper, that's good to know.

As to how I'm feeling, I have to say that my first full night of successfully using the CPAP machine and mask (which was NOT the first night I had it!), I thought it was a miracle cure, I noticed that much difference. I'm more accustomed now to it, so the difference doesn't seem so remarkable, but there is not doubt that I'm sleeping better and waking up somewhat more refreshed.

Thanks for asking!

Umm - unless you are bored, you really do not need to be here, nor do anything other than what you've been doing. If you are pleased with your sleep - you're gold.
