Anyone compare blood oxygen levels with a good dedicated pulse oximeter?

[kat.hayes]

Has anyone done a series of comparisons to check their blood oxygen level at different times and compared the readings with a quality pulse oximeter? What types of results were found?

Thanks.

i have to see my pneumo doc regularly (Asthma..) and blood oxy is being measured on a regular base. last time was the first time with my S6 and i ran my watches blood oxy test (out-of-curiosity) while having the docs device attached (the doc was curious too =)) ). The tests showed a max difference between the two devices of about +-2%. Doc and me were both surprised/impressed =)

The watch is a little more 'sensitive' when being moved during measurement; so it should being kept still during the process. The docs device did not really care when i was moving my arm while measuring.

I find them to be between 1-2% difference at most.

I've found them to be within the +/- 1-2% range of a PluseOX

I concur with the +/- 1-2% range here.

Has anyone tried slipping their finger under the watch when taking this reading?

Wonder if that'll make it even more accurate.
