That is such a great story. Did you ever find out what was wrong with the little girl - what caused the swelling?
Epiglottitis is what caused the swelling. It is an infection of the epiglottis (the flap that closes your trachea when you swallow so food doesn’t go down the wrong tube). It’s worse in kids because their tracheas are so much smaller. It happens in adults too, but kids get the worst of it.
