General questions about Sense 2 EOV data

[Marc2023]

Hi guys, I want to buy the sense 2 and need some help:

1) Does anyone know if the "Estimated Oxygen Variation" GRAPH showing the last night is available with NO PREMIUM SUBSCRIPTION?

2) Is there a graph showing the SPO2 of just 24h or 1 night and not x days? (With NO PREMIUM SUBSCRIPTION)

3) Anyone know why they call it "ESTIMATED oxygen variation"? Is it not based on acual SPO2 measurements?

Thanks for help...

Hi @Marc2023

1- EOV is available without premium.

2 - EOV and Nightly spO2 are two separate measurements. EOV is a relative measurement in relation to an unspecified baseline, and Nightly spO2 is an absolute measurement although only presented as a single nightly average figure. (see examples of both below). Non premium users are able to view a 7 day chart, with premium being able to select between 7, 30 and 90 days.

4 - As for why it's estimated. I guess because it's only a relative calculation rather than an absolute reading. Although I can't be certain on this one. 

Hope this can be of some use to you.
