Thanks, SleepyFinger. I'm sure you're right about SleepyHead missing the centrals on the non-detail days. I dropped pressure to 8, and dropped EPR from 2 to 1. First night, inconclusive, since power was going off & on (ending on Off) due to the windstorms that caused the fires in Northern CA. Last n...

I was hoping for a better night last night with new settings, but power went out at 11pm and is still out today. I do have a marine battery and inverter to run the S9 through power outages, but I realized that it was not fully charged, and it gave out around 4am (after several blinks of electricity ...

I don't think the SA changed that significantly. Looking at day-after-day AHI for nights where no detail is available is where SH shows the low AHI. Day-after-day starting on the first day of detail data, the AHI jumps way up. I think it must be in the way the SH calculates AHI when the detail data ...

Thanks so much. The weird thing about the AHI 0.89 is that ALL of the nights that only have summary data have AHI around 1 or less, while all of the nights WITH details have the significantly higher AHI numbers without any change in the treatment settings. I slowly started ramping up pressure to 8.4...

SleepyHead needs the files that are missing and the reason you don't have the detailed graphs and that's why the AHI might not match what is on the machine LCD screen. SleepyHead needs the missing files to do an accurate calculation for AHI reporting. On the nights where there are no detailed graph...

Hi all, I've been using my Resmed S9 for quite a while, and I thought I had been getting pretty decent results (Machine reported AHI usually 2 or below). I just recently installed SleepyHead and imported data. I'm assuming SleepyHead must calculate AHI very differently from the machine. The the olde...
