Newbie's AHI higher than at sleep study

[dorilu]

I started cpap therapy 6 days ago. I am using sleepyhead to monitor my progress, but have a lot to learn to interpret my results. Ay my sleep study my AHI was 10 and it was reduced to 1 at titration with a pressure of 10. My dr prescribed a fixed pressure of 10. My AHI has been increasing and last night my score was 17.64. My report flagged Cheyne stokes respiration for the first time, as well, last night. Both MyAir and Sleepyhead said to report the increased AHI to my dr. I did, and his nurse sent a prescription to my DME to increase my pressure. When I took my machine in today to have that done, my clinician, after me telling him about my mouth breathing, gave me a chin strap and advised to try that before he adjusts pressure.
My SH reports, (circle graph) show mainly CA (purple) about 2/3.
My stats for last night: CSR- 6.02%, Lg leak-6.61%, CA-12.60, obstructive-0, Hypopnea-5.07, RERA- 1.10.
I admit I don't know how to interpret this, but I have been reading the posts and trying to learn more.
Any help or suggestions would greatly be appreciated. I am wondering if mouth breathing is the problem or something else going on and whether an increase in pressure will help.

Could you please share with us that detailed SleepyHead report?
Here's how.

and what we want to see (don't need all those graphs)...you can get the basics on one screen shot.
and how to organize your image...read this...and there are 3 pages so please read all of them

Do you have a copy of your sleep studies...the diagnostic and titration? If not, get them.

6% of the time in large leak isn't horrible and it's doubtful that a chin strap is going to fix things unless the leak was so bad the machine couldn't record events correctly and so bad that your events only occurred during times of large leak.

We can help you better if we can see what you are seeing.

I didn't get a copy of my sleep study and titration reports. I'll ask or one. I will try and send you the reports. I'm not familiar with how to go about doing that so I will read your instructions and get that to you asap.

You have to get sleep study reports from your doctor - no one else is allowed to give them out.

I did the screen shot, got it uploaded to imgur but can not figure out how to send from there.

[dorilu]

I'm sorry, I was trying to say I will send the SH report data if I can figure out how to do that, not the sleep study report. I'm so new to all this and worried because instead of my AHI decreasing or at least staying the same, they are increasing. I'll try and figure out how to send the SH data.

[Julie]

Read the links you were given... a nuisance, but it's all there.

I probably didn't get everything you need, if not I'll try again. Hopefully you can get some idea from these.

Turn off the pie chart....it's hiding useful statistics and is pretty much useless anyway.
Preferences/Appearance tab...remove check mark for "show pie chart"

Look again at how to organize the graphs.
In your situation we don't really need the pressure graphs because you are using fixed pressure...for sure don't need both of them.
We do need the leak graph and flow rate graphs.

Don't try to resize the image...instead do this when at imgur..
Make sure you are logged in...have the image you wish to share in front of you...
look over to the right side where all the addresses are and right below those addresses are the thumbnail choices..
click on "huge thumbnail" normally I would say large thumbnail but that has been acting up lately...
when you click on the thumbnail the addresses in the boxes will all change just a little.
Copy the last line at the bottom of all the addresses and paste it in the body of your text here.
The end result is an image that we can click on to enlarge it if needed.
Right now I can't read your image very well because text and numbers are so tiny and I can't make them larger.

Your flow rate line is broken...which is really weird to see it like that but I don't see large leak flags at the same time.
Do you see this sort of broken flow rate line often?
Do you sleep soundly or wake often during the night?
Ever turn the machine off during the night?

I hope this is better. It wouldn't let me change pressure graft for some reason. I'm not sure what to look for to see the broken flow rate you mentioned . Yes, I wake up many times in the night but I don't turn the machine off. Thank you, Pugsy, for helping me.

Dorilu,
On the Flowrate Graph, put your cursor in the label area at the left and right click. Then select Y axis and override to change the scale to something like -80 to +80 which will make the presentation larger so that we can see it better.

You have a fairly consistent high leak rate, by the looks of the leak graph, I'm guessing it is from exhaling through your mouth (Mouth Leaks). I am also guessing that the CA's are a result of inhaling through your mouth which the machine interprets (falsely) as an apnea. You can see this thread for more info on mouth breathing and leaks: viewtopic.php?f=1&t=112758&p=1085906#p1085906

If you are breathing through your mouth, a small piece of one inch paper tape vertically from under your nose to below your bottom lip may help to keep your lips closed and slow the leaks.

I think it's just a bug... the graphics glitch now and again.

either click and drag them down below the other charts, or turn them off with the selector in the bottom right corner.
