Possible manufacturing defect ResMed AirSense 10?

Has anyone experienced bad time readings with their ResMed AirSense 10?

I was provided this new machine in March and noticed the read time displayed when turning machine off didn't correspond to actual sleep times. I've been using CPAP whenever I go to sleep faithfully for 10 years. About 5 years ago became eligible for supplies via Medicare, and somewhere along the line they began asking the usual questions, verifying use to meet their requirements. As I never sleep without it, I always qualified. My original Respironics machine started dying and was provided this new AirSense 10.

With this new machine, it records and sends all info to provider, supplier, and who knows where else, but I’m often getting incorrect readings. I can sleep for 8 hours and get a reading of 10 minutes use. Was concerned I might not qualify for Medicare supplies so contacted provider thinking I had a faulty machine.

Two days ago was provided a brand new replacement. First night, perfect read times. Last night had a bad reading so not likely 1st machine was a lemon, or getting 2 lemons in a row.

Thanks

Might depend on "when" you're checking your data. And, whether you're using the LCD info or downloading it into software like Sleepyhead. Some of these machines require that there be a certain amount of time to pass before the information is valid for the previous sleep sessions. Using software will be a better method of verifying it.

In the initial sleep report screen, the end of day is at noon, so if you sleep past noon,
it will look like you missed the entire period before noon.
The machine merely thinks it is tomorrow.
Each day's usage is calculated from noon to noon.
Maybe noon on your machine is not what you think it is.
STOP! Do not set the time yourself! It clears all usage up to then.

Changing the time doesn't clear the data. However, you can't set the clock back before the last time you used the machine, it will refuse to do so unless you erase your old data.

The A10 manual says you can't set it into a time in the past. On the S9, you could set it to a time in the past, but not before the last time it has data recorded for. It would be interesting for one of the A10 users to test this.

I find on my S9 machine that I have missing data if I take the card out shortly after turning it off.

I haven't measured it precisely, but 30 minutes seems to be long enough that the machine will write the data out to the card correctly.

Thanks Wulfman, chunkyfrog, and archangle.

This was my 1st post and I didn't want to make it too complicated. I understand and appreciate all your responses and think they sound right, especially with my sleep pattern, but a little clarification still needed before I potentially make a BIG mistake.

I usually go to sleep between 3-5 am and wake about 7-8, feed the dogs & take morning meds. I then go back to sleep ½ - 2 hrs. later, waking between noon and 2pm. Hence although the 2nd sleep session read does cross the noon hour, shouldn't the monitoring of 24 hours from 12 noon to 12 noon the following day always put me over the 4 hr. Medicare requirement as I generally get at least 7-8 hours of total sleep for both sessions even though the session after 12 noon is always less than the AM session?

Here’s what threw me:

When my CPAP provider did a follow-up call to me on the 20th, (after having received the unit on the 6th,) they said I was only 70% compliant per their transmissions from the machine. Without knowing what I now know from your responses, and never sleeping without CPAP, I was pretty surprised. Made an appointment to bring it in as I thought I should be 100% compliant.

I later remembered there were 2 nights I’d forgotten to manually turn it on; (my prior unit of 10 years auto started). I’ve since changed that setting to auto start. Even with your responses, assuming I’ve understood you all correctly, and deducting those 2 nights I forgot to manually turn it on, I should have been an absolute minimum of 88% (17 day, 2 split sessions missed). I caught my error after the AM session when removing mask; no air flow!

While there last Monday (6th), they said I was 77% compliant. That’s better, but they also said if I’m below the 70% I had shown a few days prior, not a whole lot a wiggle room which could translate to a lot of money. Of course if it continues, (above 70%) for the next two months I’m golden; if not, I’m back to spending what I was before I had Medicare; not good, especially as I’m no longer working and am disabled.

Based on your responses and as I’m always up before 4 pm, I’m thinking if I reset the time so the unit reads 4 PM when it’s really 12 noon, that should work; unless that messes with stuff on their end. Does anyone think that’s a good plan or does anyone know if or why that would mess things up? I’d think they’re getting a live read at the correct time, but wouldn't it then be interpreted more accurately per my sleep schedule? Seems they ought to have a way for accounting for peoples different sleep patterns, people that work night shifts, etc.

Wulfman, if you’re still with me, I download SleepyHead-OpenGL and SH-BrokenGL along with vcredist_x64 and vcredist_x86 for my Win 7 64bit and x86 Common Files. Tried running both as administrator but both wouldn't start due to missing Qt5WebKitWidgets.dll. Downloaded and installed missing .dll individually in system 32 & Program Files x86. I had already installed Visual C++ Redistributable Packages for Visual Studio 2013. They still failed to start, but a different code. Suggestions??

Again, thank you all very much & look forward to your continued advice.

I'm with you, but I'm not a Sleepyhead guru. Have never installed or used it for my own reports (my machines are too old to use it) but have read many reports on the forum. Some of these other folks are far more knowledgeable about installing it, etc.
Maybe they can put forth some ideas for you.

First of all Medicare only requires that compliance hours of use be met for a 30 day period withing 90 days...it doesn't require it for the full 90 days. Medicare also requires a face to face meeting with the doctor prior to the 91st day to verify that the machine is being used and is working/helping.
It is a 30 consecutive day thing but it's not for the entire 90 days. Compliance could be met on days 52 to 82 of usage.

Your SleepyHead problem...it sounds like you are trying to open/launch the program from within the zipped folder and not from the unzipped folder. Can you verify that you unzipped/extracted all files from the downloaded zipped folder and are indeed opening the unzipped main SH folder and clicking on the application.exe files at the bottom of the list?
Where did you download SleepyHead from? If from the link in my signature line you also need to download and use the 7 zip program to unzip SH because your regular Windows extraction/unzip won't work.

Thanks Pugsy!

I know I unzipped the files previously after downloading from the same link; this time using the 7 zip program as you suggested. I was still getting some error messages as before, but when I inserted the SD card, the file popped open to import from the SD card.

I then had some difficulty finding it as it defaulted to the “My Documents” folder and I don’t normally save anything on my computer; Everything gets saved to my external HDD; then backed up to another ext HDD. Double protection!

Not seeing it on my HDD, so thinking it’s a portable program? Really not sure. Hope I can get it working when I reformat which I’m having to do shortly. In the meantime, many thanks. The current data shows better compliance; I’m guessing because the 2 sessions I missed become a smaller % as the days continue to grow in number. Took a snip but don't currently see how I can attach, hint, hint! The daily chart looks like it’s going to need a looong learning curve!

Do you have any thoughts on advancing the machine 4 hrs?

Have a good nights sleep. I of course will be up for quite a while more :-)

g'night,
Lewis

As long as you know what the time is...it doesn't matter which 24 hour period gets counted. We have some shift workers and some night owls who have change the machine clock so that they don't have the splits at noon.
Medicare itself doesn't care at what time the machine is "used" ...it just wants it to be used.
Doing what you suggest will make it easier to evaluate your reports too.

How about trying ResScan until you can get Sleepyhead figured out. It can be a pain in the butt too but at least it installs normally and won't give you so much aggravation in that regard. There's no reason you can't eventually use both if you want to.
I will send you a private message in a bit so look for it.

Hi LJTMesa,

SleepyHead doesn't have an installer like most commercial windows programs. So, it's just a matter of unzipping it into a folder. Then, many people would move the sleepyhead folder into "c:\windows programs" folder. It doesn't matter where it is, but that's one of the two places that windows programs get installed. No matter where you put it, you can go to that folder in file explorer, highlight the program SleepyHead-OpenGL, right-click on it and choose "send to desktop (create shortcut)". Then you will have an icon on the desktop that you can double-click to run it.

For the DLL error issue, the answer is on their webpage at http://www.sleepfiles.com/SH2/:

Missing DLL files?
If you get a message something like "MSVCR120.dll is missing," you need to install the "Microsoft Visual C++ 2010 Redistributable Package" available at http://www.microsoft.com/en-us/download ... x?id=40784 Explanation: Some versions of Windows do not have all the necessary files. These files need to be installed with Microsoft's installer, at the link above. The missing files may not always be "MSVCR120.dll", but it will be something similar starting with "MSV" and ending with ".dll".

That was really clear yaconsult how you outlined the SH install in a nutshell... well done

Sometimes it pays to do a little math, and calculate when you need to get started on a session to put in the necessary hours.
You can check the screen to see how many hours you already have, then plan ahead to get AT LEAST enough time.
to finish with the right amount of sleep. Aiming for four hours can be trouble in more ways than one.
Most people need more sleep; five, six or seven hours is better for most people,--just generally speaking.
If you aim at five or six instead of four you will not get bitten by the "false round-up", as almost four
does NOT ROUND UP to four for the record--only on the screen! IT WILL NOT COUNT!

Thank you Pugsy. I haven't been able to find the private message; still learning my way around this very large & informative site. I did download ResSense 5.3 which I believe is what my provider uses, or one of its precursors. Per your prior info about only needing 30 days, I've already qualified so that scare is gone, whew!

I'm no longer sure about moving the machine's clock 4 hour behind noon, as I'm always up at 4 pm. Seems I've checked the time on the new machine 2x, and both times the machine was off by 1 hour. Initially I was thinking it was due to DST, but that wouldn't explain why it continues to revert to being 1 hour off. As I don't really know why, seems I should let it be, esp as I've already qualified; the man concern of my initial post. The info during the times it's being used should still be accurate so need at this point. Of course if you or anyone else knows why it would be changing it's own time, that would be interesting to me.

Thanks again
Lewis
