As far as I can tell only two studies have shown SpO2 decreases more in MECFS than controls, and at least four studies that apparently had that data but didnt report it, which makes me think the difference wasn't replicated in those studies. - ThreadSky

VO2 drops-- it's one of the most repeated findings

Right but the video said "blood oxygen". I would assume that's talking about SpO2, not VO2.

I wouldn't assume lol. That said, that's true anecdotally as well. I don't know that there are as many studies that measure SpO2

dimapodolsky.bsky.social•22 days ago

I've just never heard blood oxygen levels referred to as VO2 since they're completely different metrics, so I'm guessing a mistake, since I would think VO2 would be the stronger finding to focus on. But yeah, it'll be interesting to see what future studies show about SpO2 as well.

Thanks for taking the time to respond to my questions jaime

(I assume the other studies I mentioned tested SpO2 and put it in supplementary files, otherwise I'm not sure what the MEpedia calculated figures are based on. And AFAICT the figures in the table are not compared to controls anyway.)
