I'm shortly to see my sleep doc. He likes the ResScan statistics summary. I hardly ever use ResScan as I think Sleepyhead is so, so much better.
So I've just looked at my statistics résumé for both programmes, to print out and take with me to the appointment.
Looking at all my 122 days on ASV:
Total hours used, average daily usage, days of use - concordance between ResScan and SH.
Average AHI SH 0.7, ResScan 0.4 - but that is not an important difference.
However - ResScan gives maximum IPAP at 17.2, whereas SH statistics, SH and ResScan bar charts show it to be 23.8 (ResScan bar chart) or 25.0 (SH bar charts and statistics).
Unless all my wave form charts are wrong, 25.0 is the correct max IPAP over my last 122 days. So why is ResScan reporting the max at only 17.2?
Anyone else seen this? And it makes me wonder if some other ResScan summary stats may be wrong.
My pressures this week: Auto-ASV 11-14, PS 3-10
I have a similar issue. The difference is not so great as your with IPAP but is reasonably large with EPAP. In both cases the ResScan statistics record a maximum lower than the ResScan bar charts or SleepyHead. I notice also that the statistics page gives my maximum leak as 15.0 while the barchart shows a couple off the scale over 150. What I suspect is happening is that ResScan is reporting a mean or average maximum rather than the single peak reading. The average maximum would probably be a more useful number for the doctor to consider.
I'm only guessing at this - The ResScan manual says (of statistics generally): Maximum: The maximum value recorded during the selected range.
