Choking is a terrifyingly quiet emergency. When an object fully blocks the airway, the person may not be able to scream, cough effectively, or ask for help.

Because the brain can survive only a few minutes without oxygen, knowing how to perform airway clearance techniques is an essential first-aid skill.

Step 1: Identify True Choking

Look for the universal choking sign: clutching the throat with one or both hands. If the person can cough loudly, breathe, or speak, encourage them to keep coughing and stay close.

If they cannot make sound, cannot breathe, are turning pale or blue, or appear unable to cough effectively, intervene immediately and call emergency services.

Protocol by Age Group

Adults and Children Ages 1 and Older

1. Stand behind the person and wrap your arms around their waist. Lean them slightly forward. For a child, kneel so your arms are positioned correctly.
2. Make a fist with one hand and place the thumb side against the abdomen, slightly above the navel and well below the breastbone.
3. Grasp your fist with your other hand and give quick inward-and-upward abdominal thrusts. Repeat until the object is expelled or the person becomes unresponsive.

Infants Under 1 Year Old

Do not use standard abdominal thrusts on an infant. Their internal organs are fragile, so use back blows and chest thrusts instead.

1. Place the infant face down along your forearm, supporting the jaw. Keep the head lower than the chest.
2. Give 5 firm back blows between the shoulder blades using the heel of your hand.
3. If the airway remains blocked, turn the infant face up while supporting the head. Use two fingers in the center of the chest to give 5 quick chest thrusts about 1.5 inches deep.
4. Alternate 5 back blows and 5 chest thrusts until the object clears, the infant breathes, or emergency help takes over.

If the Patient Loses Consciousness

Gently lower the person flat onto the floor and call emergency services if you have not already done so. Begin CPR starting with chest compressions.

Look inside the mouth before giving breaths, but do not perform a blind finger sweep. A blind sweep can push the object farther down the airway.

Never delay emergency help when choking is severe. Airway obstruction can become fatal within minutes.
