Just take a baseline, don't worry about what that value means, just worry if it changes by more than a standard deviation.
As a good nerd I bought my pulse oximeter in early days, but I (a) know that I've had poor measured blood oxygenation since at least my mid-20s, (b) have no idea how bad that actually is, either under the threat of COVID or generally & (c) have no idea how to interpret my #'s now

I mean, OK, but does this hold if my baseline is 95%? 92%? 88%? What's a standard deviation for this measure, and is that really the right unit for concern if I'm already a standard deviation — or two — below mean? I don't mean to pick on you, but these feel like important Qs

It's almost always just a bad plethysmography tracing. Are your fingers cold? Try running them under some warm water and then using the pulse ox. Or put the pulse ox on your ear lobe.

Do you have a baseline (e.g measuring first thing in the morning) from back when you bought it? If so, you could just reference to that. If not, then best establish a baseline now.

I think low SpO2 is probably a bit bad generally but we don't know how to fix it, it's probably a bit bad for COVID but not too bad (maybe 2x as severe depending on how low SpO2?), & you should probably just be using pox to confirm your baseline has dropped if shortness of breath

You want 3 things during COVID pneumonia: 1 is to not be low on oxygen for extended periods, 2 is to be prepared for quickly escalating treatment if it snowballs or gets worse fast, and 3 is to be able to take medicines that look good but aren't FDA approved

Just know what is normal for you, where you live. If you function ok at that level then it’s fine for you. Note that if you live at high altitude — Denver etc — then normal will be lower than at sea level. Driving over the passes around Tahoe is enough to drop me to 90 or so!

Hi, I am a medical doctor, search for something called the S curve of hemoglobin, like many biological and medical stuff it's more complicated that just aritmethic or standard deviation, even the slightest drop means trouble, 89% means a real trouble if you are young and have...

Simptoms aka shotness of breath. Here is a great explanation, hope it helps:https://youtu.be/HYbvwMSzqdY

I got one early too. My approach is taking readings from all members of the household regularly, especially when they aren't feeling well, and keeping records of them so I'll notice outliers. Also, I wear it while holding my breath or laying prone to watch the oxygen stat move.
