Abdominal thrusts, also known as the Heimlich maneuver, should be given just above the navel on the person's abdomen in case of choking.
Abdominal thrusts are not used any more for unconscious choking. Perform chest compressions just like in CPR instead of abdominal thrusts.

If abdominal thrusts (Heimlich maneuver) are performed, ensure that the person is truly choking and unable to breathe, cough, or speak. Stand behind the person, place your arms around their waist, make a fist with one hand, and position it just above the navel. Grasp your fist with your other hand and thrust inward and upward sharply. After several thrusts, if the person does not become unblocked, call emergency services for further assistance.
you should look in his or her mouth if the object hasn't came out if not , keep doing abdominal thrust until item is out . but if the item is out . you give two rescue breaths and abdominal thrust until child becomes responsive .
If the person is choking and coughing, continue to encourage them to cough. Tell someone to call 911 (emergency services - the number is different for different parts of the world), or call 911 yourself if you are alone with the choking person. Watch for the inablilty to talk; difficulty breathing or noisy breathing; lips, skin or nails turning blue or dusky; inability to cough forcefully; loss of consciousness. If you see any of the above signs, then give 5 back blows followed by 5 abdominal thrusts. Continue with the back blows and abdominal thrusts until the object is dislodged. If the person becomes unconscious or stops breathing, give CPR.
To give thrusts during a rescue maneuver, such as in the Heimlich maneuver for choking victims, first, position yourself behind the individual. Place your arms around their waist and make a fist with one hand, placing the thumb side against the middle of their abdomen, above the navel. Grasp your fist with your other hand and perform quick, inward and upward thrusts. Repeat until the object is dislodged or the individual can breathe again.
When helping a choking child, you should give back blows and abdominal thrusts (the Heimlich maneuver) if the child is conscious and unable to breathe. For infants under one year, use a combination of back slaps and chest thrusts. Always call for emergency help if the child is not able to breathe or loses consciousness. If the child becomes unconscious, begin CPR and continue until help arrives.
The Heimlich maneuver (now called abdominal thrusts by the American Red Cross) is done by making a fist (pac-man / thumb facing the stomach) with one hand and on the stomach and the other hand, open-faced, helping to push the fist up into the diaphragm. That in-and-up ("J") motion applies pressure to the diaphragm, essentially knocking the wind out of you (your goal, of course). That motion should be done as hard as possible. To give you an idea of the amount of force needed, a colleague of mine did abdominal thrusts on his brother's son, an 8 year old boy who had choked on a piece of hot dog. He did four abdominal thrusts with no success. On the fifth try, the thought that he said went through his mind was "Oh my God - if I do this any harder, I'm going to break this kid's spine" and sure enough, the piece of hot dog came flying out. It takes a lot of force!
