other Airsense questions / issues

Post by InsomniacGuy » Tue Apr 14, 2015 9:18 pm

Hi folks,

I've noticed in the past 2 weeks that I am seeing big gaps in data ranging from 1 hour to 3 hours in my Sleepy Head program. Sometimes I see the leak rate graph zoom up -- so perhaps the mask moved? Other times, there is no such increase in the graph...

Any ideas? Perhaps the mask is getting old? Or...?

Also, noticed the machine has ended up on its front face a couple of times. This second time, the tank leaked water... Anyone else with this experience?

Thanks.

I had a similar experience with data loss with my s9. Is you auto on/off turned on? It may be that a large leak is causing your s10 to turn off, then turn back on when your mask gets a good seal again. Your machine getting turned over may be another indicator of you moving around alot in your sleep, dislodging your mask causing the machine to turn off. A hose management system may help you control this...

Thanks. I'll look into the auto on/off. Didn't know that existed!

Here's another issue for feedback from other folks.

Allegedly, the Airsense hypoallergenic filters are replaced once every 6 months. But, here is a photo of it at 1.75 months with dark splotches. Is this what other folks are seeing? Also, is the filter letting dust through? I see white spots of dust-like particles inside the inlet hose and in some patches of the black plastic recessed area... see second photo.

What do you think about doubling up on the filter? -- since my setting is at 8.0 cm H2O, I figure the machine can handle the increased pressure differential with a second filter. Thanks.

6 months, OR AS NEEDED.

there's dark splotches, but there's a lot of filter that isn't clogged yet, just the bit right over the inlet hole, but the standoffs keep the filter out so that more of it can be used.

no, the filter isn't 100%, so very fine stuff can get through.

I use a plain and hypo filter on my machines. ... and then a antibacterial filter on the output, just to catch all the allergy making stuff that I can, so as to have a less stuffy nose at night. (yes, before the chorus of "you're not breathing filtered air the rest of the day" people start up)

Rotate it 180 degrees. Keep the same side of the filter facing out, but move dirty spot around.

A dirty air filter usually filters out more crap than a clean filter, but it restricts air flow more. If it gets clogged too dirty replace it. If it looks dirty enough to block much airflow, or it stinks, replace it.

As for air leaking around the filter, use some care when replacing it to minimize this, but I suspect it's not too big of a problem.

I wouldn't worry about it too much. The filter is there to protect the machine, not you. It's nice to breathe filtered air, but you breathe unfiltered air 16 hours a day when not on CPAP.

Thanks, folks! The dual filter approach is working for me... Now that I see the black particles being filtered, I wonder if I can find a way to breathe filtered air for the other 16 hours a day? :/

Here are a few more Airsense questions / issues:

1. The side of the unit that the filter and SD card are located will stay warm when the unit is either in standby mode or powered off (by depressing the power button for a few seconds). It is cool-to-the-touch only when the unit is unplugged. Any thoughts as to the cause of this? I would have thought that the transformer block would be the only part staying warm when plugged in.

2. Now that the air is sufficiently humidified, I do not put water in the tank. Any advantage to improving tank longevity if I buy the side cover?

3. Does the data live on the machine and SD card -or- just the SD card? I want to remove certain days of data from the machine / SD card. In either case, does anyone know what needs to be done to erase certain days of data?

Thank you!

regarding the 'missing' data, you could be experiencing brief power outages. notice any other appliances displaying the symptoms of being turned off and on again?

Summary data is stored on board the machine and written to the SD card as well. Also summary data will be written to the SD card when it is inserted if the SD card is missing any of the summary data. Summary data includes usage, overnight AHI, and maybe the 95% leak and pressure data.

Detailed data is written directly on the SD card and is NOT stored on board. Hence, if a Resmed user leaves the SD card out overnight, all the detailed data is lost forever: There's no way to recover the detailed data graphs in SH because it wasn't recorded in the first place.

I'm no sure by what you mean when you say that you want to erase "certain" days of data. For the on board data, there's no way that I know of to selectively erase certain days, but leave other days' data alone. You can purge all the patient data by resetting the patient therapy hours to 0. But that's not really what you want to do.

If you are using SleepyHead, it's easy enough to turn unwanted sessions "off". You could turn off all the sessions for an unwanted day, and that would effectively make SleepyHead ignore those particular days.
