to upload the data. While I recorded for 6 hours and 8 mins the oximeter session showed up as 9 hours 15 mins! I uploaded it again on a different computer and it showed up as over 24 hours! I uploaded it on yet a 3rd computer (all using Sleepyhead) and it showed up with yet a 3rd session length all longer than the actual recorded session! It synchronized fine with the beginning of the CPAP session but the oximeter session continued for a longer time. Looking at the pulse and O2 data in the region of the overlap, they don’t even look quite the same comparing one of the computers to the others even though the data came from the same recording session.
Any ideas about this? Has anyone seen anything like this? It doesn't really inspire confidence as far as relying on the data.
Here are screen shots from two of the uploads:
