Can anyone interpret this SPO2 summary?

I got the report from a pulse oximeter. It does heart and oxygen. Can anyone tell what is wrong please?

It can also print out a line graph, I see I go below 88% at times... is that normal sometimes?

https://ibb.co/GHmVQHG

basal SPO2(%) 92.9

time (min)<88% 1.1

events <88% 13

minimum SPO2 (%) 84

avg low SPO2 (%) 89.9

avg low SPO2 <88% 86.3

I don't test for oximetry but I found this document on a quick google search

I am a technician, and not a doctor, so I cannot give qualified medical advice. Also, the information you have given is limited but I'll do my best. If you are an otherwise medically normal health adult then that suggests that your oxygen levels are a little bit low but not alarmingly so. If you have a history of smoking, pulmonary fibrosis, or some other condition that affects your respiration then this would be roughly normal. It appears that your oxygen level dipped a little on a few occasions during the night (13 times for a total of 1.1 minutes). If this was measured over a night of sleep that would not be enough to cause concern in the normal course of events, and could easily be explained as entirely normal fluctuations in your breathing here and there. If you do not have a history of smoking, or something else which would explain slightly reduced respiratory function, then it would be worth discussing this with a doctor because it is a little low (as far as I can tell from what little information there is). It's not panic stations, but it is worth investigation.

"(13 times for a total of 1.1 minutes). If this was measured over a night of sleep that would not be enough to cause concern in the normal course of events"

1 minute doesn't sound bad, but could it be disturbing sleep patterns so I don't get any restful sleep/consolidation?

If I consistently get these type of results (not just one off) could that account for feeling fatigued?

To get a clear picture of what's going on you really need a proper sleep study, although it is unlikely that 13 events in one night are causing that much disruption however they are spaced. Having said that, if CPAP makes you feel better then there's no reason not to use it because it's completely harmless. There are some people who's sleep apnoea is not significant according to all the guidelines, but it is still enough to make them feel really tired, and CPAP makes them feel much better. I'd just be thorough with your investigation before throwing too much money at it. Oximetry on its own is pretty limited.
