Almost always, when the detail data (mostly the graphale stuff) is missing, but the summary data is present, it's because the SD Card was not present in the CPAP, while the sleep session was occuring.

This is how it works:

• Detail data is written to the card during the sleep session, if the card isn't present, the detail data is not written and will *never* be written for that session.
• Summary data is stored in the non-volatile memory of the CPAP. It doesn't need the SD Card present when it's accumulating it. Upon insertion of the SD Card it will update the SD Card.
• There *seems* to be an increase in problems with missing detail data with Air 11 devices. This suggests that there is an SD Card slot change that is prone to improper seating of the SD Cards.

When you move the SD Card back and forth between the CPAP and computer *daily*. This increases the chances of forgetting to insert the SD Card, or it not being seated correctly.

In another post you mentioned, you keep a card over your CPAP display, therefore you don't see the SD Card insertion message. This may be a key issue to resolving your problems.

Consider:

• Do not wait until bedtime to put the SD Card in the machine, if your session starts before the SD Card is inserted and mounted (indicated by the message) you risk not getting your detail data.
• Put the SD Card back in CPAP immediately after importing into your computer
• Take that silly card of your machine display.

When I put the SD card back in last night I initially got an error message about SD card not being inserted correctly. What I HAD been doing was taking it out in the morning, popping it online, then putting it back into the cpap machine right away, within minutes. But it is deff possible that it wasn't seated correctly. However, I DID fix it last night and imo it SHOULD have written the data correctly on it, but it just didn't.

I had three successful nights of data followed by 3 that were off in some way. Oddly, the AHI and any use at all did not register on the myair app two days ago and today it is there. (I didn't look closely at it yesterday morning because I had an early appt out of town and just didn't have time to look at it until evening.

I suppose I should take the flap off the front but I just hate to wake anyone with my bathroom breaks. I don't wear my glasses in bed so most of the time I can't see what is registered on the front of the screen anyway.

I DID notice there is a more detailed screen option which unlike the "stupid screen" they gave me at setup, this one will provide on the screen a greater breakdown of incidents, leak issues, pressure ave etc (if I recall correctly.) I still can glean some info but not waht I want.

Taking your suggestions under advisement.

I noted previously that someone mentioned a wifi sd card. I find this idea intriguing as you wouldn't have to pull the SD card in and out daily. Even better if I can transfer to my phone. The toshiba wifi card did not have great reviews for the app. My newer iphone likely will not support, according to comments/reviews. Then there are wifi adapters for microsd chips that are priced pretty low.

I really want to be able to tap into my data but don't want to run the risk of damage.

If only.....

I use the Toshiba FlashAir wifi, I have been for 4 years and it has worked very well for me.

• It's been out of production for a few years now and demand has put the prices through the roof. Good luck finding one for less than a couple hundred bucks.
• It (as most) wifi SD Card has got a very weak signal and sensitive to distance and congestion issues. Therefore, it must be in close proximity to your WiFi router, approximately 30 feet with out significant obstacles.
• They can be finicky to set up.
• You need a third party system to transfer the data to your host computer, or capable in manually moving the data or scripting it.

SleepHQ is Beta testing its proprietary "Magic Uploader" system to move data from your CPAP to the SleepHQ cloud. It uses a wifi card and Raspberry Pi to solve the distance and scripting issues. I don't see this as being an inexpensive solution.

I have seen a few. Oddly they are cheaper on ebay if I buy from German seller. Like under $50 cheap iirc. (maybe it was one of those other cards?)
I have a very small portable hotspot. I can bring them right next to each other. My phone has a hotspot also.

I saw that the two main wifi sd cards each have their own app. The toshiba reviews said once the iphones went to IOS13 the chip wouldn't work with the app anymore so that kinda rules that out. Not sure if it would transmit to the mac we have at home or if it would have the same issues.

What do you use to extract your data? Ideally I would like to be able to use my phone. I have a PC at the office as well but dont take it home often.

I keep seeing how this type of photo or that type of photo can be transferred but unsure how other types of data would be transfered since this isn't being used for intended purpose of a camera offload.

A phone based "hotspot, won't help you. Hotspots are used to give computers/devices access to the Internet. You need to give the WiFi SD Card access to your computer.

The intent of most of the WiFi SD Cards was to transfer pics from cameras. Therefore they are graphics oriented. Some SD WiFi cards can only transfer graphics.

I use both Mac and Windows.

I use SleepMaster to transfer from the Toshiba FlashAir to my computer. SleepMaster works for both Window and Mac. Unfortunately, the Author died a couple years ago and the source code has never been made public. I don't know if it works with Air 11s.

The files are available on Apnea Board, but you must have an account to see the post for the links.

The other transfer app is FlashPAP available here: https://www.cognitial.com/apps/java-app ... or-footer/

Both Apps are written in Java, specific to FlashAir. Unfortunately, Apple crippled Java a while ago, they took away the ability to run Java apps from the desktop launcher. You can only run Java apps from terminal.

Apnea board has a few topics on running scripts to transfer data from FlashAir and a few other wifi cards. But, it really is painful watching non-technical struggle with networking, scripts, ip addresses, connectivity and config files trying to get setup.

sounds simple enough

thanks for the good info

If you do manage to buy a FlashAir, the following post shows how it can configured for use without additional software.

Y'all are making me think I should just stick with S9 and it's data as I have now started to be able to sleep on my side and seeing a return of AHIs of zeros to a high of 0.6 finally.

BTW, this all after I got my pressure
range optimally set. Seem to remember Rooster and LinkC (remember them all you old-timers?) helped me setup switching to an APAP, the Innomed now RespCare Universal Hybrid FFM, setting low pressure less than median & slightly higher than my lowest recorded pressure with max pressure suggested by my sleep doc. I had already dispensed with ramp and the humidifier (I live in the humid South).

I posted the following on another thread, in response to lynninnj's questions that evolved into a discussion of range.
I suggest that if the discussion of range continues, we continue it here.

I feel as though there’s a misunderstanding and I don’t know how to fix it.

My median pressure was obviously going to be higher when the pressure settings were higher.

Here's where the misunderstanding starts.
The median of any distribution means that 50% of the cases happen at or below the statisitc (the "thing") we are measuring.
The median, as I noted in my previous post is far less affected by extreme values than the average.
You can spend 5% of your time at a maximum pressure of 20, and that will have absolutely no effect on your median pressure.
You can spend 20% of your time at a pressure of 4, and that will have absolutely no effect on your median pressure.

In your example, your minimum pressure was 8 - the machine could not go lower than that.

lynninnj wrote: ↑

Sat Aug 20, 2022 2:30 pm

Because the median pressure was just above the minimum pressure, I wanted to try lowering it a bit just to see what the response was.

So you lowered you miumum pressure. But what was your response to the change? How did feel you and what was your AHI when you spent more time at lower pressure?

Now the median pressure is a little bit lower

And that indicates that you did indeed spend some time at pressure lower than 8.
S0?
What was your response to sleeping more of the night at lower pressures? How did you feel and what was your AHI when you spent more time at lower pressure?

You will have the correct setting for you - the sweet spot - when you sleep well and feel great at the lowest pressure necessary for that to occur. The machine will not - cannot - tell you what the sweet spot is.

Another important bit of information to consider:
Which mode is our machine set to run on? The lower median means far more when your machine is in Autoset for Her mode, because in in Autoset for Her mode the machine itself changes the minimum setting it uses during the night. In regular Autoset, it will drift down to the lowest pressure you give it, and rev up in response to events, again and again. In Autoset for Her, the machine says "uh oh, there were 3 obstructive apnea within X minute[s], I'm not going lower that tonight!" that might result in higher median.

I am going to carry over my response from the other thread here as well. And then I’m going to add on a little bit.

THANK YOU

THIS is the info I feel I was desperately in need of.

I FEEL better with the lower number of wakeups. I am seeing the numbers creeping up even before the pressure change. That’s why I felt maybe a tweak was in order. Goodness knows sleep doc was unhelpful (“you need a special card for that” and “you can’t read the data on it anyway “) I am not sure what changed between when I had ahi under 1 and now between 2-3.

Am I expecting too much?

What do you regulars consider the sweet apot for you? under 5? 1?

I had a period there where I felt GREAT and now seems herder to find. thus my quandry.

I want so much to learn more and spend less time defending myself because tone inflection and meaning can be lost in a forum such as this.

This morning’s update:

I had kept it at six for a minimum pressure for a few days after seeing sleep doc. It didn’t drive down the numbers. Then I squeaked it up to 6.6 for a few days. It didn’t drive down the numbers. Last night I said it at seven and the numbers went down a little bit. I am going to leave it there for a few days.

When I asked this question dog slobber gave me some excellent information about the electronics. I still haven’t taken my sd card out in 3 days since having zero data on it the other day and about a week of no ahi listed. And a few other topics as well from other posters. I didn’t find what I was looking for though and I did a search on the words optimal pressure and found a different slightly recent thread.

There was a lot of good information there.

But when I asked a poster a specific question I got beat down for it. Someone said once most people here are sleep deprived. Maybe some consideration should be extended.

Thank you for the thoughtful replies even the ones that weren’t necessarily what I was looking for her

"You can't always get what you want, but you might just get what you need"

if you're lucky

I just watched video posted on mouth appliance thread about mouth breathing and Nick discussed this video here: https://youtu.be/pL4egwDrvbg

This is pretty much the answers to my questions. whew!

I am not wholly sure I need to drop the upper limit much if at all though because I don’t get a lot of leaks. Maybe I will look back at data to see if the leaks are waking me up.

Thank you all who have helped.

So.....I followed the suggestion by Pugsy to unplug/plug device after returning the SD card. This seemed to have worked.

Now, I look at the data with concern at all the centrals.

Learning to read this is on my to do list. But for now I am still trying to find the pressure range sweet spot here on this thread.

https://sleephq.com/public/81a99bca-dbc ... f1a971f35a

I started out the first few hours with the bleep mask. The water in the mask woke me up on one occasion which I ignored as a "tickle" and rolled over to go back to sleep but when it woke me a second time I went and put my N30 on. (I had a cozy on the bleep too and it wasn't enough. Problem for another day.)

That said, if anyone can help provide some direction it would help. If someone looked closely at a patch of time and said hey, that looks real or that looks fake, that would help.

I didn't register any "large leaks" but I do see some leak activity. I think maybe the strap was stretched and not holding as tight as it should. I am switching it out tonight and will try ayrs or lanolin to help with seal. Probably going back to N30 but maybe give bleep another go with different wrapping (and no ayrs or lanolin.)

Thanks to anyone willing to offer a helpful response.

Maybe 3 real asleep centrals....probably sleep onset. Rest of the centrals are probably arousal related and to be ignored except that they point to a potential arousal or awakening.

First OA flag was the real deal and there was one other later that appeared to be asleep related. The rest of them are most likely arousal related.

Leaks aren't horrible but there does appear to be some increased leaks at a lot of times when there is evidence of arousal breathing. Which came first...don't know for sure. Not always easy to tell.

The machine at the current settings seems to be doing a great job.

Leaks could be causing arousals....they don't have to be big to disrupt sleep.
