A: You unwrap it.
I've heard so many birth horror stories ending with "...and the cord was around the baby's neck!" Most of the time, a nuchal cord is of no significance to the birth process. You simply unwrap it after the baby emerges.
I'm thinking of making another video using footage from Inga's birth, titled "What if the baby doesn't breathe right away?" Her resuscitation was slower and less aggressive than NRP protocols, though. I'd probably need to make a note of that...
Dramatic effect thanks to Igor Stravinsky's "Rite of Spring" and Claude Debussy's "Reverie."
