[Diagnosis] O2 Ring - what is the use of pulse & movement data?

[JoeDoe]

Hi, All,

I've been using the O2 Ring occasionally.  The value of the blood oxygen level is obvious, but I'm not clear how to make use of the pulse and movement data.  I can see spikes in the pulse and movement data, but I don't know whether they are just normal, meaningless spikes.  So questions like these arise: How many spikes are just normal and mean nothing?  How big does a spike have to be to be of concern?  And are there more subtle questions that should be asked than simply counts and magnitude?

I've attached a sample night's data for illustration.  Clearly some of the pulse and movement spikes correlate with events that the machine identified, but other spikes don't correlate.

Thanks for any insights you can offer!
