I use a ResMed S9 AutoSet and find a data (previous night AHI, CA, OA, etc.) discrepancy between what the LCD panel on the S9 indicates (usually higher figures) and what the SSD card shows when opened with ResScan software (usually lower figures).
What could be the reasons for these differences?
Many thanks for your help and advice on this issue.
The S9 summary LCD screen gives the index for all events regardless of type.
The number of CA + OA + HA divided by hours slept is reported on the screen as the AHI.
Using ResScan, on the night's Statistics Tab, you'll see it broken down by type:
CA/Hours and HA/hours and OA/hours. You add those 3 numbers, and it should equal what the LCD reports.
