How to deal with Choking

Scenario:You're friends and you are eating pizza at a your birthday party.Suddenly one of your friends start gagging(not from the terrible taste) and looks as if they have trouble breathing.What do you do?

Well you shouldn't punch their stomach like in action movies and don't go patting their backs like you're trying to get a baby to burp.No this is what you do

One thing for sure:CALL 911 IMMEDIATELY!!!!
1.Get them to stand
2.Bend their upper body forward and smack their backs(not too hard) 5 times
3.Next put your leg between theirs and cover your dominant fist with your other hand
4.Press underneath their diaphragm and then pull your fist up
5.Keep on doing this until the food pops out

Why do you do this?
Think of as a cork on a champagne bottle.If you put pressure on the bottle there is a likely chance the cork with pop out from where it was stuck.Same thing as choking,when your putting pressure on diaphragm the lungs build up pressure,and to release the pressure they blast it up the windpipe and out comes the lodged food piece.

What is choking?
When either an animal or human have severe difficulty in breathing because of a constricted or obstructed throat or a lack of air.
