Sorry for the delay. I was damn tired to use my PC the last 2 days because of this problem Sad

Would this be fine? Is this as expected?

RE: PrismaSMART and artifacts
I'm trying to see the flow waveforms, which are very compressed since the flow range is from -100 to 100. Try setting this range it until the waveforms fill most of the range, and set the time range to 2-3 minutes.
See attached example from Sleepyhead where the waveforms are clear.

ah, I guess I got it. The example helped. How about this?

Yes, this is clear, these wave forms are really flow limited breaths, not errors from the cell phone or software.

ah Ok. How did you identify these flow limited breaths? Why do you think they went away after a particular day without changing any CPAP settings?

1. plateau or multiple peaks, see Fig 5 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4688581/
2. normal night-to-night variance, sleep position?
