Critically hypoxic but totally calm. How long till irreversible damage?

So I was in a discussion at work over the phenomenon of the “[happy hypoxic](https://en.wikipedia.org/wiki/Silent\_hypoxia)” patients that we experienced during COVID-19 and that occurrs in [certain conditions such as HAPE](https://youtu.be/AdG5KyeIGaQ?is=ZnCo3jjHxiHq1KUU), and it occurred to me that I have no idea how long someone has when they reach a critically hypoxic SAO2 or measured SPO2 in the field before they start seeing true end organ damage that is irreversible, or start seeing hypoxic insult to their brain.

Is anyone aware of any research out there that actually says that this is the critical intervention period or timespan before irreversible insult occurs?
