[Equipment] SpO2 Sampling Rate - Apple Watch

[Elroy]

Hi there,

I think the SpO2 sampling rate is important to get useful informations. The OtwoFellow-Ring (=Circul-Ring) has 1 Hz = 1 measurement per second.
Knows someone the SpO2 sampling rate of the Apple watch? Can you really do something with the information of SpO2 from the Apple watch?

Sorry for my bad English, 
best regards

Martin

Additional question:

Which device can you recommend me for useful and meaningful SpO2 measurement? What about the Wellue o2 Ring?
Thank you!

Hi Elroy! -
Since that oximeter in not available in the U.S, I am limited on the information available to me. Several oximeters have the 1 Hz rate, but only record a sample every 4 seconds. You need to look at their software's sampling rate.

Worth a read comparing the Apple Watch to medical grade equipment.
