Total volume of lungs is ~6 liters, and "tidal volume", the amount of a
single breath is ~.5 liters at rest. So perhaps as many as a dozen breaths
(a minute or so) will dilute the oxygen content down to where you lose
consciousness, though exertion could reduce this to as little as 2 or 3
breaths.

Not because of a whiff of N2 no. I do not know how many times one can

I read of people stepping down a few steps down a ladder inside a tank,unaware it had been nitrogen purged. The treacherous thing is one breathes
quite normally in N2 but O2 is missing: sudden collapse and death is
likely, without warning or ill feeling. Such happened on several occasions
in chemical industry, even some who went down for help without an air
blanket perished.
