Pulse ox accuracy

pulse ox on the FR945 show 92-95%, regular “pulse ox on finger” show 99-98%. What is your pulse ox numbers? Did you try to compare with other meter?

I have compared to a high-end Nonin Pulse Ox and the 945 is at typically 4-5 points lower. I wish there was a way to calibrate this sensor.

My FR945 reads about 3 pts lower than my fingertip meter and my Fenix 5x plus. I have compared the F5x+ reading with a reading in the doctor's office several times and they were within 1 point each time…

My sleeping pulse ox seems to dip into high 80's/low 90's at certain times during the night...i can almost certainly confirm through my wife that i do not have sleep apnea. i think the dips happen…

I turned it off long ago as a battery draining waste of time!

The watch must be worn above the wrist bone line to be accurate within 2%. I tested mine at work, I am a Respiratory Therapist, and it was 95% on my wrist and 97% on my middle finger with the HR being the same on both.

Yes,. I have the same readings as you do. My FR 945 reads around 4% lower than my finger pulse oximeter.

that gives me some peace of mind. During sleep I gained an average of 89%. During the day on average 94%. That is both way too low of course... Thanx for your test!
