My Garmin watch has a pulse oxygen readout. I wonder if the same patent applies...

  It was mentioned in a previous thread that Garmin uses a different method.

  There are apparently different methods. Apple Watch 3-5 created vo2 max data without a pulse oximeter.

    Garmin watches don't use the blood oxygen sensor for estimating VO2 Max.
