Please help me make sense of this

Post by old dude » Sat Aug 17, 2013 7:25 am

I thought I had a pretty good night last night; 0% LLs and an AHI of 0.65. But the AHI graph in SH seems to show an AHI higher than that. Looks like it's almost up to 10.

Am I misreading something?

I had the same problems with Sleepyhead and had to go back to Rescan. The pressure graphs sometimes don't match the settings on my machine as well.

Old dude,

This looks like a decimal point error in the SH AHI graph since it looks like you had 3 events all night long. The SH AHI graph should have gone to one after each of those events and stayed there for a full hour before dropping back to zero.

I'd report the problem to JediMark through sourceforge.net---particularly if the problem occurs on multiple days worth off data.

By the way, it's nice to see that you've gotten the leak problems you were having under control!

Thanks so much Robysue, I must admit I'm holding my breath on the LLs but so far here's what I've done:

*Wash my face with soap and warm water every night before retiring (previously was just wiping down with washcloth and hot water)
*Disassemble the mask every morning and wash the seal with baby shampoo
*Talked my doc into lowering my pressures on a trial basis down to 15/11 from 17/13. It doesn't seem to have negatively impacted my numbers, does it? After about a week at 15/11 I'm likely going to do a little DWing myself and take it down to 14/10 to see what happens. You wouldn't think a couple of centimeters pressure would make such a difference in leak management but it sure seems to!

The Mirage Quattro is not the easiest mask to disassemble daily and I suspect it will shorten the life of the seal constantly removing it and reinstalling, but for right now it seems to be working.

I appreciate all the support.
