Can I still delete & reimport SH data from Dec. 21-28?

From Dec. 21-28 I was importing oximetry data into Sleepyhead. When I started looking at my overview bar graphs last week, I found that the AHI bar graphs were messed up for those days. That's because I was on CPAP for fractions of a night (to limit aerophagia), but doing oximetry recording for the full night. 

Importing the oximetry file did not change my apnea statistics at all; it just lowered the height of the tri-color bar for those days. This bugs me because it's hard to get a real overview, and it was hard to explain to the sleep doc last week, even though I drew lines on my paper copy where the top of each bar should be.

If I delete those days now, will they re-import from my SD card? And where are the directions for making the attachment big?

   

On this chart, where I selected all the nights since I've had the pressure on 6 cm, Dec. 27th has an AHI of 11.85 and Dec. 20th has an AHI of 11.59. Oximetry data was imported on the 27th, and deleting the oximetry doesn't fix it. I was on CPAP for 4h 08m and on the oximeter for 8h 13m.

Go to each day and delete the data then reimport from the SD card the gaps will be filled in

Thanks, jaswilliams, that worked. How long does the data stay on the SD card? Until I delete it?
And how do most people back up their SD card data?

Most users create a directory on their PC and copy the entire contents from the SD card to this directory.  Always answer Yes for the overwrite prompts when you copy.  This will allow the summary database files to be updated.

Thanks, CN, that was easy. There's already 70 MB on the card! When I run out of space, I'll need to have another one ready to go. Any idea what the capacity of the card is? It has very faded printing on it. I can't read it.

I think the A10 will use up to 4Gb before it starts to overwrite the oldest files first.  Nowadays finding an SD card that small may prove impractical. The A10 can use any SD card up to 32GB.  I recommend that you keep a spare in case your current SD card fails.  SD cards are sold at almost any pharmacy or big box.  Look for the best value.
