I have attempted to find information on this in the OSCAR documentation, and by searching here. I've failed. OSCAR 1.5.1, MacOS.
Changes to device settings shows a series of things, one of which is FL, which I assume to be Flow Limitations, and would assume from the data reported above to be 95% flow limitations. Unlike the AHI column, which appears to track with the statistics above, my FL column is always 0.00
I don't know if this means the FL down there is some other FL stat, such as the Med from the daily reporting, or what.
