How Low Can O2 Go Before Symptoms?

[Guest guest]

I don't have an oximeter for home use yet. I was wondering what the

experience is of others when they take off the O2 and the level drops.

At what O2 level do you start to have symptoms such as shortness of

breath or light-headedness or dizziness? I can do a lot without the

O2 before I feel symptoms. Am I harming myself if I am not wearing

the O2 but I don't have symptoms?

Thank you.
