Heck, I bet even Zonker liked it! - - So, now the graphs are making more sense...at least the flow graph!!! Got any more??? - I sure hope you're not going to leave us mere meat bags!

i liked YOURS more, particularly the title of palerider visits earth.

That video, the graph you shared and your explanation was the most helpful information I've seen or read since being diagnosed with SDB or OSA about 2 weeks ago! - - I'm sure many other new members appreciate you sharing that information palerider. Heck, I bet even Zonker liked it! - - So, now the graphs are making more sense...at least the flow graph!!!

Zoom in on your individual breaths, then look for places that you see activity in the flow limitation graph... you should see different shaped inhalations (the part above the zero line on the flow rate graph (you do have the zero line turned on, right? right click 'flow rate' on the graph, then 'dotted lines' and turn on zero)) a couple breaths before the flow limitation graph kicks up... (FL's are coming off a moving average, so the bumps in the FL graph don't correspond exactly with the breaths).

Probably.. heh, but like pugsy, i work better when prompted with questions. feel free to prompt.

Not planning to just yet, some of you are quite entertaining, plus I'm still gathering data. Who knows, maybe I can sway some opinions back home.

It looks like there just might be light at the end of the tunnel...

There is, and most of the time, it's not an onrushing train.

Well luckily, things are still moving down the track nicely... I ended up with a 1.48 last night...and no large leaks!

I'd like to figure out the interplay of the various graphs...ie, flow limit (which I understand to be a much lower level obstruction...<50%?) - Little by little, I will get a handle on this...even if I'm just a meathead!

I'd increase the min to 14 and see the results, it may need a bit more

Okay palerider, lots of food for thought. I studied the correlation of my flow limits, flow rates & leaks...very interesting. It appears that my flow limitations are minimal though, no? And funny enough or not, my hypopneas, which I realize is an entirely different thing, seem to be very minor.

I'd say the flow limitations are minor, yes. And given that the latest chart show zero flagged hypos... yeah, I'd say those are minor too.

My hope is to control what I can control through cpap therapy such that my sleep time is as healthy as can be and that I get the best rest possible. - - I guess that's everyone's goal!

That is the goal.

Another question: I see people mention oximeters...do they serve any useful function in conjunction with the cpap therapy? Or is it something not to be concerned about?

One of the goals of treating SDB is to eliminate oxygen desaturations, the other, of course, is to reduce sleep disturbances so you can rest. For the vast majority of people, getting the apnea in check takes care of any o2 desats. Some people aren't so lucky. Some people (like myself) just want to play with an oximeter... and see for themselves what's going on. By and large, it's not something to be concerned about.

ajack- Thanks for your input, but I think I should hold off increasing my minimum to 14 since the Resmed machine sometimes goes to 13.? ; at least I think it might help to keep that as is for now. Any thoughts on this palerider?

My thoughts? Ajack is best put on the foe list. He reads a huge amount of stuff, but has superficial understanding. he's admitted to posting while drunk... and while he's certainly not always wrong, he's not a reliable source of information.... It's not worth the trouble trying to find the occasional nugget of accidental good advice in amongst all the mine tailngs.... he's also happy to argue *endlessly* with people that have more knowledge about "how it should be"... or whatever.

I'd like to see a few more days where you are, pressure wise, then *maybe* bump it. That could smooth out the pressure line a bit, but .... it may not be necessary.

One thing, when you've got a chart like the last one posted, where there's a nap or something, and a very large gap in the data, scroll down on the left, and turn off the short session, so that the main night's data fills the screen. makes it less scrunched

Thanks very much palerider! I didn't know you could turn-off mini-sessions as you described. I was going to take my SD card out of the machine to prevent that from happening in the future (scrunched data). I've re-posted today's activity without the mini-session. I'll tally a couple more days with the hope that things (AHI & leaksI) stay low. Thanks again!

Taking the SD card out won't prevent those mini sessions, it'll just make them look bad since the machine will write summary data about the session, but no detailed data... best to just leave it in, and then turn them off when posting.

You're doing really well for someone who's so new to therapy.

wow! i have to add to what palerider says about you doing so well. i just scrolled back to your first post(not even a week ago!) and am astounded by your progress, at least ahi-wise. good work.

but, as always, i have to ask...how do you feel upon wake up?

Thanks zonker! - When I woke up, I felt zonked!!! jk...lol...

It seems I'm sleeping a lot less than I used to and overall, I feel pretty good!

most excellent. both of those are indicators that your therapy is getting tuned in.

we'll see what palerider has to say about your latest chart.

Thanks palerider! Last night was a bit off for me... AHI - 3.75 and I had about 3 decent leaks...with a p10!!! The leaks were about 13, 10 & 11 minutes long. - According to SH, I was in Large-Leak-Land for 7.9% of the time...not good!

But, as long as the leaks weren't waking you up, not necessarily bad. The main problem with leaks like that is that if you'd had an apnea, the machine might not have been able to differentiate whether it was central or obstructive, and would have flagged it as "unknown". There's no problem with maintaining therapy pressure with the leaks... so as long as it didn't wake you up... not good, but not all the way into bad... Now, if they were longer, or woke you up, then... bad.

Plus It seems the Resmed should get a "piling on penalty"... between 4:50 & 6:00 I had something like 13 events!!! I'm thinking some of them may not have been legit...I was waking up around that time initially and then dosed-off again.

Yeah, if you're drifting in and out of sleep, that'll very often cause a lot of false events.

Hey, I included my Tidal Volume chart to get any feedback. I think it's looking pretty good, no? Is there anything in particular that causes it to go up and down? I realize it is what it is and therefore I probably shouldn't be paying any attention to it...

As you're learning, sleep isn't a constant, it goes through phases, and your breathing changes... and that's just the most basic part of the variation.

As long as leaks don't wake me up....I don't even bother to look at the leak graph until I hit 10% of the night over the red line.

I didn't see it suggested, I would use standard titration procedure and continue to raise the min pressure, 1cm at a time till the OA/H resolve.

Posted by someone that's confused an in lab titration process with sleeping at home.

not confused at all, following basic titration procedure beat the hell out of the nonsense some say.

...the "bad news" is I forgot to put my SD card back in the machine!!!

Look for a Toshiba WiFi SD card and Flashpap then if your Autoset is close enough to your wifi router no need to remove the SD card from the machine.

Hey Jas, that's pretty cool! I didn't know those things existed. So, I can get a 16,32 or 64 gb Toshiba FlashAir card. I'm guessing 16 gb is probably plenty big, right? What do you use? - - I don't imagine I would be using the card for anything other than the Resmed... Btw, thanks for the tip!

I use the FlashAir as well, Really like it.

• No forgetting SD Card in computer.
• No forgetting to lock/unlock write protect (important for ResMed s9)
• No wear and tear on SD card or reader

The 16gb capacity is well beyond what's required for SleepyHead, so get the cheapest available. I use the W-04 16gb version, with SleepMaster to transfer data.

Thanks Dog Slobber! I'll order the same one. Talk about opening Pandora's box, I never heard of SleepMaster!!! I can see it is used to transfer data wirelessly...very cool!- - Is that mainly it's function, or does it also provide for analysis of cpap data like SleepyHead?

Funny enough, It seems the more time I spend on this fourm, the more I learn! Thanks!!!

SleepMaster does have some graphing ability, but I've never pursued it. I use it strictly for transferring the data.

Either SleepMaster or FlashPAP can be used.

After the new SleepyHead/OSCAR team port their first version and start considering new features, I'd like to see FlashAir directly supported.
