Yikes!!! Whatever happened to the "warm & fuzzy Dr. House stuff"???

Apparently, you never saw the show

- - Although the colors & actual avatar(?) looks pretty cool!!! Btw, you're not changing already, are you???

"changing"? what is this "changing" you speak of?

The AHI graph is nothing but how many events happened to average within a 60 minute segment...it resets every 60 minutes. So a per hour average vs an all night average AHI.
Might be marginally useful if you had a dense cluster within say a 30 minute time frame but then again you can usually spot that easily enough on the Events graph....or go to the Events tab and eyeball the timing of whatever events got flagged.

Totally useless if your overnight AHI isn't very remarkable and maybe marginally useful if something hugely bad happens with dense clusters of something.

Woohooo...My Toshiba 16gb Flash Air arrived today! - No more forgetting to put my SD card back in the machine...everything gets transmitted remotely via WiFi to SleepyHead (soon to be Oscar).


I went back to my Airfit P10 last night... no leaks to speak of and zero large leaks!!! AHI - 2.32 OA - 1.29 CA - .26 H - .77
Hoping to get things below 2.0 soon, maybe even 1...

Well, I've gotten below 2 ahi over the last couple nights. I'm posting the 2 most recent nights to see if the experts, palerider et al, have suggestions...good, bad or otherwise... Btw, pay no attention to the first "date" that says 2021; that was merely 2 nights ago.. I've since fixed the date... No more "back to the future"!!!

Time traveling again, eh? that WILL mess up your sleep, there's a guy on another forum who got his machine in June 2019, and he's having temporal flux issues with his sleep, I'm not quite sure if he'll have to wait till June for them to ease out.... Temporal mechanics gives me a headache.

A couple minor changes I made to last night's settings is I only had ERP...(okay pr, EPR ) on during the ramp period; I had the starting ramp pressure last night on 13.4 rather than 12.4; I don't know how wise these changes were, i.e, do they make a difference? - Probably not.

They have the effect of *raising* your pressure, since URP *lowers* your pressure... and might cause a few more events.

Btw, does the AHI graph/chart at the bottom tell me anything useful??? I realize the bottom charts are not important, but thought I'd ask if there's some hidden gem there...???

The AHI chart is a perfect example of "HEY! Look at this thing I can do!" .... "yes, but just because you CAN do something doesn't mean you SHOULD... The ONLY purpose the AHI chart has is to say "hey, you seem to have had a cluster of events at this time"... something that's patently obvious just by glancing at the Flags chart

Same thing with the Respiration Rate chart... people get freaked out because it says that their breathing is 50+ breaths per minute... but then you zoom in and look at the breaths, and it turns out it's really 16, with a little wavyness caused by the person's heartbeat showing up in the airflow (It happens sometimes.. something about the way they're laying)... yet every time that flow line crosses zero, SH counts it as a breath, even if it's just *barely* over the line....

Btw, has anyone seen Zonker??? - - I saw his pic on a Milk carton the other day...

I'm sure he'll be glad (whereever he is) to know you care!

This probably derives from the German word stumm meaning silent. The phrase keep schtum (variously spelled 'keep stumm', 'keep 'keep shtoom', 'keep schtum' etc.) is British and fairly recent. It has the sound of a Yiddish phrase but it is more likely that it originated in the UK criminal community.

Question about REM sleep. I recall reading somewhere that your pressure could go up during cycles of rem... Every 60-90 minutes. Is that right? Would that explain cyclical upswings in one's pressure?

Some people will have their OSA be worse during REM stage sleep (supine also)...and some people might need substantially higher pressures during REM.
Not everyone of course but it is fairly common and when it does happen it is fairly easy to spot when REM likely occurs.

My own in lab sleep study back when I was getting the diagnosis.....AHI in non REM sleep was maybe 12 but in REM it was 53 AHI.
So about 5 times worse in REM and I also happen to sometimes need 6 to 8 cm more pressure only during REM than what I can get by with the rest of the night.

Not everyone will have supine sleeping or REM stage sleep worsen their OSA and/or need more pressure but it isn't uncommon at all.

Palerider-

I hope you're not schtum like Zonker had been!

Like Pugsy says.... it can. but it's not guaranteed.

Well, if you get rid of the squidgy meatbag full of variables, we could make things more consistent.

The article said they even used rats in the study! I wonder if any of our guys made it...???

zonker has been missing on and off.. hmmm.

Btw, a while ago at a party I was talking with a family member about her new Resmed - - Sounds like a great party, huh??? She had 50 or so ahi in her sleep study... She got a new Resmed Airsense 10 Autoset from Kaiser Hospital. She's had it for a month at the stock settings of 4-20... No changes to her settings at all!!! What do you make of that???

I'm not sure what you're asking/saying... her AHI hasn't improved, or the hospital hasn't changed her machine from the stock 4-20?

If the latter, then ... well, that's sadly very typical... instead of the "ok, let's see what a night or two looks like and make some adjustments", all to often it's just "here's an auto machine, have fun" or at best "come back in a couple *MONTHS*"..

No wonder so many people fail cpap.

Well, surprisingly her ahI oftentimes gets down close to 5, sometimes a little less sometimes more... of course, that's pretty good considering she was at about 50 on her overnight sleep test. it just seems odd to me that they didn't narrow down the pressure ranges after a titration study. But then you mentioned that this is the way CPAP often times works. Not so good... We are all LUcky to have found this forum to get things more precise. Thanks Palerider!

Get her in here, we'll get that 5 closer to 1.

So many "sleep professionals" don't understand how auto's work, they think "well, it's automatic, I don't need to do anything"...

4-20 (the machine limits) were the old 'standard', I've been seeing 5-15 or 6-15 a lot lately, but that too is a crappy setting for most people, and dumb, because they think "you need a narrower range when what is really needed is a higher minimum. (which, admittedly narrows the range, but people that do that lower the max, instead...

And, yeah, you say 50 to 5 is a big improvement, just like only having one broken leg is better than two broken legs and a two broken arms... but it's still not *good*

They set mine at 8-24. My machine goes to 25. Don't know where they pulled 24 from. ok maybe I do know where they pulled it from but this isn't the bum thread.

Maybe it's the 'we can't leave it at default, they'll think we didn't do anything" syndrome.
