SpO2 way off reality

Hello,

got a F8 47 mm. titanium lase week. I noticed that SpO2 tracking is really unreiable. Mine is always between 96 down to 80% (!), while a medical-certified pulseOx recorded 99%.

I'm tracking SpO2 over 24h, and all values are really low.

Do you experience the same?

Is there a workaround or it could be fixed via software?

Thanks.

Surprisingly enough, I find Fenix 8 spo2 way better than with my previous watch. Before this one I had a forerunner 255 and spo2 was stupid: 96%, 92%.. I compared with a medical device and I can confirm my spo2 is more 98-99. So no I gave up.

And I tried with Fenix 8 and now I have consistent results around 97-99, which seems more realistic. I always used health snapshots, I never tried continuous spo2 monitoring though.

Just to follow up to my own post: I still get SpO2 too low: today I reached an 86% (!) at 200 mt. AMSL and 93% as average. Watch is tight enough on the wrist. I really hope it's a bug. Is there anyone from Garmin that could report the issue?

Thanks.

Have same problem with my Fenix 8 solar. Measurements spo2 all time 3-5% lower then medical-certified pulseOx.

Similar low results. Enough that the watch recording at 88-92% had me go to the doctor. Medical grade sensor indicated no issues. Average is about 96 - low but ok. Relieving but also frustrating that it is so far off.

Spo2 viene registrato durante il giorno o la notte in maniera continua presenta sempre risultati bassi a causa dei movimenti del polso. Per una lettura più accurata è indispensabile rimanere completamente fermi con una lettura istantanea.
