You never know when you'll have to use the Heimlich maneuver or CPR to save a life.

Can you imagine what it must have been like for these parents, watching helplessly as their son was choking? They had no choice but to hand him off to strangers, hoping someone would know what to do.

Watch the tense moments in this video, as the strangers work to revive the unconscious child.

After watching this, you might want to look into CPR training with the Red Cross. Hopefully you never have to use it...but if you're ever in a situation like this, it could save a life.
