She sees a red-faced student --- Her timely intervention saved his life!

A student was quietly heading down the hall corridor towards the school bathroom when the candy he was eating got stuck in his throat and he started choking.

Incredibly, a science teacher, Ms. Betsy Berry, was in a position that allowed her to see his red face, from the inside of her classroom and to understand that something serious was going on.

This teacher's fast thinking and her impeccable application of the Heimlich maneuver were captured by the school's video surveillance cameras.
