First ask, "Are you choking? Can you speak?" DO NOT perform first aid if the person is coughing forcefully and is able to speak. A strong cough can often dislodge the object.
If the person is choking, perform abdominal thrusts as follows:
- If the person is sitting or standing, position yourself behind the person and reach your arms around his or her waist. For a child, you may have to kneel.
- Place your fist, thumb side in, just above the person's navel (belly button).
- Grasp the fist tightly with your other hand.
- Make quick, upward and inward thrusts with your fist.
- If the person is lying on his or her back, straddle the person facing the head. Push your grasped fist upward and inward in a movement similar to the one above.
You may need to repeat the procedure several times before the object is dislodged. If repeated attempts do not free the airway, call 911.
If the person loses consciousness, start CPR.
If you are not comfortable performing abdominal thrusts, you can perform back blows instead on a person who is choking.
