Garmin vivoactive 4 pulse ox not working. PITA (and four days of lost data as a result) I've set the watch as my preferred tracker, I've turned pulse ox readings on, but it always shows no data. So I read your post yesterday, and I had the same issue. The SpO2 requires a snug fit on the wrist to function. Turning pulse ox on makes the heart rate not function properly. . So I switched to the VivoActive 4S, the watch. Remain motionless while the watch reads your blood oxygen saturation. The SpO2 readings are very responsive to movement when analyzing your oxygen saturation and your elevation. Is this an issue with the watch, or am I doing something wrong? I have the Venu and my Dad has the Vivoactive 4, and we both have similar issues. To do a reading I usually have to stay extremely still or even rest my arm on something. It is a very nice device. Tips for Erratic Pulse Oximeter Data If the pulse oximeter data is erratic or does not appear, you can try these tips. Wear the watch above your wrist bone. My sleep tracking is also poor. The watch should be snug but comfortable. Adjust the fit of the band. Battery life has been draining pretty quickly, from 100% to 82% in 14 hrs, but I have been fiddling around with it quite a bit, changing watch faces, downloading widgets, etc Hi, so i just bought the Vivoactive 4s in powder grey, just to find that both the pulse ox and GPS wont work. It seems that the biggest obstacle is movement for the sensor. Ensure you remain still while it is detecting. But zero SPO2 data is being captured! And no settings in the smartphone app related to SPO2 (where on the vivosmart it was in the smartphone app) And now I dug and found it, have to dig through settings in the vivosmart itself. No heart rate readings at night, and no graph of movement during the night or sleep stages. I have a full heart rate gap during the night when Pulse Ox was supposed to be working. jycca brtxxv gozfoc uzsdxyp ysjfzs cnbrpn cnus fvuymhkl cehwp kmxcj
