Abdominal thrusts

Choking - Heimlich maneuver

Choking is when someone is having a very hard time breathing because food, a toy, or other object is blocking the throat or windpipe (airway).

A choking person's airway may be blocked so that not enough oxygen reaches the lungs. Without oxygen, brain damage can occur in as little as 4 to 6 minutes. Rapid first aid for choking can save a person's life.

Abdominal thrusts is an emergency technique to help clear someone's airway.

First Aid

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:

You may need to repeat the procedure several times before the object is dislodged. If repeated attempts do not free the airway, call 911 or the local emergency number.

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.
