Can anyone explain why the "events per hour" number and the "AHI" number match each night when the AirSense10 is set to report results one night at a time? When set to monthly, those numbers do not match each night. In both cases, the numbers are different between nights. I am reading the numbers on the AirSense10 screen, not off of the SD card.

The events per hour is just an alternate way of saying AHI.

So when you have report period set for one night it will be the same........but when you change the report period to say one month for example the report is giving you the AVERAGE AHI for a one month period therefore the month average will not match the one night figure.

Also be aware that a quirk of the Airsense.....if power is interrupted for any reason the report period will default to one month average.
