My brother is choking at dinner! Please help me to save his life! I don't know how to do the Heimlich Maneuver!
Don't panic! The Heimlich maneuver is a first aid procedure used to treat upper airway obstructions (or choking) by foreign objects. Here’s how you can perform it on an adult or child over 1 year old:

1. Stand behind your brother with one leg forward between his legs.
2. If he's a child, move down to their level and keep your head to one side.
3. Place your arms around his waist and make a fist with one hand.
4. Place your fist just above his belly button and grab it with your other hand.
5. Make a quick upward thrust into their abdomen.
I cleared the obstruction, but now he isn't moving or responding to my voice!
