Maybe I'm wrong (not a doctor), but I believe it is very unlikely that one off events of apnea lower your saturation to a level of clinical relevance to need 2s frequency; saturation drops only after a continued chain of such events or some sort of constant obstruction (COPD, asthma exacerbation, etc). Also, though sample of n = 1, training for freediving my breath holding PR is 3m31s, and my SpO2 barely went down. The CO2 reflex kicks in before O2 goes significantly low.

In my experience with the O2ring missing a breath or three isn't really noticeable. but I was experiencing prolonged periods of obstructive sleep apnea and it was very visible on the SpO2 graph, I could see every (infrequent) breath. Not clear from the article how serious "screen apnea" might be; the health threat it identifies is just the stress of it, not oxygen deprivation.
