If you are alone at home and find that you are unable to eat
following some piece of food stuck in your mouth then you should try
to find a table or a chair and strike your stomach against it. That
can be repeated until the food piece comes out and breathing
restarts. You can also make fists of your hands on the stomach and
fall to the floor. Usually you cannot breath.
In some children who have taken a sticky candy the usual maneuver
may not get the candy easily out as it is sticky , so you have to
turn the person upside down and jerk them up and down and maybe hit
on the back to get the sticky candy loose.
If you see a person seated next to you suddenly stops talking and turns blue, you know that the person is not breathing. Then jump and stand on his back, give a bear hug around him with your fists against his stomach , just below the ribs. Then pull the stomach back with all your force and the blockage will be removed.
