We bought a CMS50F oximeter; I used it for the first time last night. It was a bit tricky importing data to SleepyHead. I couldn't figure out how to pull the SP02 file into SleepyHead via the "Import from a datafile saved by another program", but was able to get it via the "Import directly from a recording on the device". Because I was careful to start and stop it at the same time as my CPAP, the data is reasonably well synced. Interesting stuff!
My question here is, does anyone know how to set the oximeter up with more than one profile? My fiance wants to try it tonight for sleep, and he may also want to use it for aviation purposes.
Also, when SleepyHead went to import the data it said something about the device having a different name, and told me to rename it. Anyone know how?
The 50F is not smart enough to recognize different profiles. It just records one session at a time and that session must be uploaded before the next one, or you will lose it. That said, if you want to have multiple users of the oximeter and be able to distinguish the data in SH, I recommend creating multiple profiles in SH instead, and then uploading into the appropriate profile depending on who wore the oximeter for the last session. Also, the 50F has an internal clock that I have found to be pretty accurate, so I rarely have to adjust the time offset in SH when importing. Sometimes there is a couple of minutes of drift after an overnight recording, so I set SH to sync the clock automatically. I occasionally reset the clock on my CPAP machine too.
I echo the above comment about using 50F while doing anything other than sleeping. I tried to use it while running once and it was completely ineffective. I wasn't sure if it was the movement or ambient light interfering with the spectrometer. Either way, though, the data sucked - completely useless.
