Strange and sudden recent change in Data, AHI etc.

[qwawawawa]

Hi All

Fairly new around these parts (I very recently had the fun of having my Philips Dreamstation Go refuse to turn on when arriving at a hotel for a business trip... see my other thread).

See attached for a few SleepyHead screenshots from my Resmed AutoSet S9 (I think?). I use a Nasal mask and generally sleep well.

What happened on March 26th? Everything changed after that...

Either something changed with me, my mask and machine or it's an artifact of how the machine stores data.

I've only done a single import of data.

Does the data age-out after one month? Is SleepyHead able to see detail further than one month back?

Anyway - have a look and I'm really interested in your suggestions!

Thank you

The Resmed S9 stores 365 days of summary data 30 days of detailed data an 7 days of flow information. If this is the first time you have imported into sleepyhead you need to ignore all data before March 26th as sleepyhead needs the detailed data to calculate the AHI correctly. if you want to correctly analyse the summary data then you will need to get resscan look at this thread http://www.apneaboard.com/forums/Thread-...Only-FILES

Resscan correcty renders the summary only information but it is a windows only application and a large download.
