SpO2 is 92% on Fitbit Versa - should I be worried?

[Martincho8002]

Hello, All,

I've recently activated the SpO2 clock face on my Fitbit Versa. I can see that my Oxygen level is 92% or 93%. I read that normal range is 95-100%. Should I be worried or see a doctor? Thanks in advance

That's in normal range for sleeping overnight; the higher range is for daytime awake.

Thanks for your reply @JohnnyRow . However, the Versa measures SpO2 only during sleep, yes? or am I mistaken?

Correct, it measures only during sleep, so there is chance you will never see that 95-100%, unless maybe as the upper limit, but not likely as average.

From What should I know about SpO2 values?  

"SpO2 values naturally vary, and nighttime SpO2 is usually lower than daytime SpO2 due to the fact that your breathing rate is usually slower during sleep. In general, SpO2 values during sleep are typically above 90%. The SpO2 values presented are an estimate and in general can be influenced by your activity, altitude, and overall health."

I have SpO2 sleeping range of 92-95%. I purchased an oximeter (on sale for $14.99) and periodically test my daytime SpO2 score. I average 95 to 98%. For peace of mind, you may want to considered purchasing one. 😀

It’s a bit low and may indicate apnea…an oximeter used during the night and Not the day may be worth investing in. Your doctor can refer you to a specialist who will send you home with one too.
