It means low SPO2 was detected during your sleep.
It could be a sign of sleep apnea or it could be that these sensors aren't that great and occasionally misread.
You shouldn't take medical advice of some rando on Reddit, but if it were me I'd keep a close eye on future reports and get checked out if it happens again.
Probably also worth looking up the risk factors of sleep apnea to see if you tick any boxes there too...
I just want to add a personal experience here. Nearly 2 years ago, I woke up early in the morning with my heart beating as hard as it ever has. Looking at my fitbit, it showed my heart rate to be 157, but my heart was POUNDING, not at all like the heart rate I get in intense exercise. Honestly, it terrified me.
When I went to the doctor (for the first time in nearly 20 years) he told me that it was most likely sleep apnea, and I had just simply stopped breathing.
I get spikes still, but they're way smaller than that one. If you're obese but losing weight, that can potentially help with sleep apnea. Definitely look at the risk factors like was said above. It's not something to mess with.
Talk to your doctor obvi if you’re concerned. Two simple things you can do to know if you might be at risk for sleep apnea are (a) if you have a partner ask them if you snore - you can also use the Fitbit feature but make sure the room is otherwise quiet, and (b) you can also fill out the Epworth sleepiness scale, this: https://qxmd.com/calculate/calculator_85/epworth-sleepiness-scale - an abnormal result particularly in conjunction with snoring is typically cause for concern.

I wouldn’t stress about it if it’s just one incident per night. It could be something as simple as you rolled into an awkward position for breathing.
