Pulse Oximeter and sleep data

One of the theoretical uses of the pulse oximeter would be as an indicator of obstructive sleep apnea (episodes of hypoxia during sleep associated with heart rate elevation and perhaps motion). Is this currently part of the sleep analysis readout of the new 5X+?

    Simple answer is no, not based on my usage in the last 24 hours

    can you give some more details, when you see pulse oximeter data and under when circumstances it is recorded?
    I assumed that once a minute Pulse Oximeter will be stored and can thereof be analyzed in garmin connect app.

    +1 here, this feature is too hidden from the users. We jus have to trust it's there :)
  • Hello,

    I have read the Review from DCR (DC Rainmaker) which also covers Pulse OX here

    Collecting a reading takes anywhere from 10 to 30 seconds, and is generally most successful when not moving (just pausing for a second while walking is usually good enough in my testing). This is in line with how most climbers monitor these levels today – pausing to use small sensors to take readings.

    So it seems that there is no Auto-Pulse-Ox-measure at cerain intervalls and thereof it's not possible to get oxygene-measurements to learn more about sleep apnea.

    To me it seems that the only difference between the Garmin 5X Plus and 5 or 5S is actually the Pulse Ox measurement and the different battery runtime.
    Is this true?

    If this is true and with the way Pulse OX has been implemented I am thinking about getting the Fenix 5S Plus as replacement for my Garmin 5X.
    Music, NFC, Maps is present on all devices and I think the processor is also the same on all modells?

    I like the form of the 5S much more compared to the 5X Plus (Display to Bezel ratio).

  • There is an option to have "all day" measurements (but there is no indication of the frequency during the day. The graph on the widgets shows the last 24h (with a 1h interval, or the last 7 days (afater pressing the start button). A measurement is also done a couple of seconds after you display the widget (that's the manual mode).
