I am getting wildly different results for <total desaturation events> and I can't work out what is going on.
I use a Contec CMS 50F oxymeter and import the night's data into the software that comes with the oxymeter, <SpO2 Assistant>, then print out the <oxymeter report>.
I also import the oxymeter data each morning into Sleepyhead.
I have set both programmes to the same definition of a desat event i.e. <drop in SpO2 by at least 4% for a minimum duration of 10 seconds>
But the programmes are reporting hugely different numbers of events e.g. last night Sleepyhead tells me I had 198 events in total, and SpO2 assistant tells me I had 15 events in total. I would judge the O2 graph suggests that 198 is the more accurate.
My cardio is keen that desat events are minimal (to avoid sympathetic nervous system stimulation of the cardiovascular system).
Does anyone have any ideas please about what might be going on with the software?
