Thing is, you can add oxygen. It's getting rid of the stuff you don't
want that's a problem.

But yes, some sort of oxygen meter is needed. I don't know anything
about meters that can directly monitor oxygen levels (other than
knowing they were part of the hazmat team's gear at one place I
worked).

But a pulse oximeter will at least register the oxygen level in a
visitor's blood, and sound an alarm if it goes too low. And they are
widely available, just spendy.

Monitoring for too high an oxygen level is im****tant though. Don't
want extra fire hazards.
