Yep, it's called "happy hypoxia". Doctors are so dumbfounded by it that most of them deny that it exists, and when presented with evidence, just pretend the oximeter was faulty.
It is probably involved with nitric oxide, which counteracts CO2

I'm what doctors would call a "moderate" case, and I've had O2 sats as low as 65%...but they always go back up to 98 after a minute or so.
was this before COVID?
I've seen people walking around with low sats as well, this was before COVID. Its pretty common in the hospital. Alot of old people sit low on thier sats at rest, we generally give them O2 via nasal canula depending on diagnosis. Alot of people desaturate during the night from apnea and can go down to the high 70. Also, alot of people sat low due to vasoconstriction or poor circulation. Theres alot that goes into O2 sats.
With COVID I worked with quite a few people who would drop momentarily with thier sats when acutely sick. As long as they came back up within a few minutes I tend not to think much of it.
As for the young boy, it seems that something went wrong with the ECMO set up. The ECMO pumps can cause a lot of issues just like vents, although via different mechanisms. For example the filter that oxygenates the blood for the body can lyse the red blood cells, among other complications such as coagulation issues and catheter issues that can lead to serious events like what happened with this young boy. The build up of blood in the chest cavity indicates to me that something else may have happened besides COVID related respiratory issues. One of my closest friends is an ECMO nurse, I lived with him this past year, so I got a decent run down on the pumps and the issues that can arise. Just for basic context I'm a nurse as well, just in a different area of nursing.
