Last year April, I've got my S9 updated from 0604 to 0905 by ResMed support personnel. The motherboard was replace since 0905 version includes more than software changes.
BTW, the skewness problem was solved in 0905.

I have experienced same problem. But it doesn't usually happen.
When it happens, I just sleep without the machine. Because I was told by Resmed that APAP may cause CSA.

Finally the doctor agreed to order me a sleep study.

Thanks everyone!

Just as an observation - my sleep study results showed a total AHI index of 21.3 with 97 events per hour - considered severe by my neurologist. From the time the sleep tech put me on CPAP in that same study, my AHI has been less than 1.0 - every night since (18-months ago) it's around .2, and neuro...

Thanks IndyDave and Emilia.

Normally, I eat lots of vegetables, and sometimes I use multi-vitamin pill. So, I'm not suppose to lack of vitamin.
Of course, it's a good suggestion, I will talk with doctor about this.

You could be waking up from the machine itself--8 to 17 is a pretty wide setting, and it forces the machines to "chase your apneas". The pressure changes could be what's disturbing your sleep. If you can print out your data, we can help you narrow that range and you can see if that helps you sleep ...

Thanks Grand-PAP.
Replied your PM.

Your AHI is low... very low for most of the people on this list. What does the data say? What is your pressure? Your in Finland. As an Aussie who has 4 very close Finnish friends.... are get you getting enough sun? Also don't dismiss depression. Post your data. Let the people here let you know what...

An AHI of 1.6...even if it were all "true" centrals is probably still within acceptable limits. Remember the less than 5 AHI standard? But you are still feeling crappy.... Have you thought about adding a overnight recording pulse oximeter to see if your oxygen levels are okay? How many hours of sle...

I think the fact that you feel lousy all the time should be enough to convince the doctor, but if it's not, is there no other clinic or doctor to see? I was going to suggest you try a FF mask, but if you've tried some (which ones?) were they fitted properly? Maybe you need a different size, etc.......

Please help me to convince the doctor to get me sleep study. Hello everyone. I'm Yimeng. I'm 23 years old guy who study in Finland. I have been on the forum for 2 years since I started CPAP treatment, though I rarely post or reply. I've learned a lot from here. Thanks to you guys! I've diagnosed OSA...

Don't be so serious. I was using humidifier when i was travelling with FINNAIR flight. As long as I have the permission to use cpap on board, no cabin crew has checked if i was using humidifier.

You can use S8 filter on s9 machines.
I've been using it on my s9 autoset, it works fine. I threw it away since I've got s9 filters for free from local hospital.

When I was ordering my S9 Autoset, resmed said that they will give me the card reader if I want. That how I got it.
You can definitely use a generic SD card reader. My laptop has the internal card reader, it works for resscan.

hi jedimark, Sleepyhead 0.86 doesn't work with win7 64bit. When I was importing data from SD card, win7 pop-up a window said that the program has encountered a problem. Same error with XP MODE. Version 0.85 works fine, but it doesn't display the SPO2 data (CMS 50F). Here is a snapshot http://images...
