Actually, the very direct feedback I got from my instructor/friend was:
"What the heck were you trying to do, conserve ambient air?" meaning I could have just as easily closed the DSV and removed the loop from my mouth altogether - No OC, no BOV, just shut it down.
His point was that I shouldn't have been on the loop once this started - I could have switched to OC or closed the DSV prior to making ANY move
You forgot-
Don't make it a problem and it probably won't be a problem! 
It takes a BIG person with a genuine desire to educate and inform others to openly share a story like that. Glad you're still around to share it! Losing a friend has never been one of my strong points- so let's make sure it don't happen!
Oh yeah... Here's some Green!
