How is breathing low oxygen saturated air more dangerous than holding your breath?

583 viewsBiologyOther

I’m doing emergency rescue for work and learnt that inhaling a few times at below 10% oxengenated air will leave you pretty much immobile, but I can hold my breath for at least a minute, so shouldn’t I be able to go without 02 for a similar amount of time? Sorry if this is smoothbrained, I tried googling it and couldn’t find an answer for this specifically.

An anectode to answer your question: I recently went to a hypoxia chamber. When we were in the chamber which was filled with nitrogen, and the test had concluded, the instructor had us do lung packing with our oxygen masks on, so that we could quickly take off our masks, sanitize them, and then leave the chamber without becoming hypoxic again.
