#IDMastodon How accurate are Apple Watch blood Ox readings ? unlike medical-grade #pulseoximeters 🍎⌚️ can't use the common transmissive pulse oximetry where light is passed through a thin part of the body, instead has to rely on reflectance pulse oximetry where light is passed into the wrist and only the reflected light is measured at the photodiode. This approach is considered more challenging as changes in spO2 tend to produce smaller changes in the signals which also appear to be less stable
