Do apenas occur in everyone's sleep to somedgree?

The respiratory disturbance index (RDI) — or respiratory distress Index — is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs).

Thank you Neicy.

Here's a link to a study that was published in 2015 using the most up to date equipment and definitions (which have changed over time) to see just how common sleep apnea and sleep disordered breathing is in the general population, note these people did not have symptoms of OSA or SDB, they were just regular folk undergoing a sleep study for the purposes of research.

https://www.ncbi.nlm.nih.gov/pubmed/25682233

The median AHI index was 6.9 in women and 14.9 in men. The prevalence of moderate-to-severe sleep-disordered breathing (≥15 events per h) was 23.4% in women and 49.7% in men.

The authors of the study say "In our study, almost every individual had some degree of sleep-disordered breathing.".

How do I know what my night time O2 levels are and what is considered "normal" (there is that word again)?

Get a recording oximeter, such as the CMS50F, it straps on your wrist then a sensor goes on a finger. levels above 88% are considered 'no cause for alarm'.

True - I look at my numbers in Sleepyhead and they don't indicate the quality of my sleep - they indicate my apneas.

What I have been looking at is total time in apnea.

So I think of it like this - my total time in apnea ranges from about 45 seconds to less than 2 minutes during let's say 4 to 6 events over 8 hours.

I think of each apnea as if holding my breath for 15 to 25 seconds and how that would affect my body.

Do apneas affect your body like holding your breath as far as oxygen levels go?

Pretty much.
