First Aid for a Choking Adult

Published: October 19, 2026Updated: October 19, 2026

Choking occurs when a foreign object lodges in the throat or windpipe, blocking the normal flow of air. Recognizing the universal sign of choking and acting swiftly with back blows and abdominal thrusts can save a life. Follow these step-by-step instructions to assist a conscious or unconscious choking adult.

Quick Summary

Alternate between five firm back blows and five abdominal thrusts (the Heimlich maneuver) until the airway clears, and begin CPR if the person loses consciousness.

Step-by-Step Guide

1

Assess the Airway and Encourage Coughing

Quickly determine whether the obstruction is mild or severe. If the person can speak, make sounds, or cough forcefully, their airway is only partially blocked. Encourage them to keep coughing forcefully to dislodge the object on their own, and do not interrupt their efforts.

Important: Do not deliver back blows while the person is coughing forcefully, as this can inadvertently lodge the object deeper into the airway.

2

Recognize Severe Obstruction and Call for Emergency Help

If the person cannot speak, breathe, or make sounds, or is clutching their throat with both hands (the universal sign of choking), act immediately. Instruct a bystander to call 911 or your local emergency number and retrieve an automated external defibrillator (AED). If you are alone with the conscious victim, provide physical intervention immediately before pausing to call.

3

Deliver 5 Firm Back Blows

Stand to the side and slightly behind the choking person. Support their upper torso by placing one arm across their chest and lean them forward at the waist so gravity can assist in clearing the object. Using the heel of your free hand, deliver five distinct, forceful blows between the shoulder blades.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

If back blows do not clear the airway, stand behind the person and wrap both arms around their waist. Form a fist with one hand and place the thumb side against the person's abdomen, just above the navel and below the ribcage. Grasp your fist with your other hand and pull sharply inward and upward, performing five rapid abdominal thrusts.

Important: If the person is visibly pregnant or has severe obesity, place your fist over the center of the breastbone (sternum) instead of the abdomen to perform chest thrusts.

5

Repeat the 5-and-5 Cycle

Continue alternating between five back blows and five abdominal thrusts without hesitation. Pause briefly between thrusts to check if the object has been expelled. Keep performing this cycle until the foreign object is dislodged, the person can breathe or speak, or the person becomes unresponsive.

6

Transition to CPR if the Person Becomes Unresponsive

If the person collapses or loses consciousness, gently lower them to a flat, firm surface on their back. Call emergency services immediately if not already done, and begin standard CPR starting with 30 chest compressions. Each time you open the airway to give two rescue breaths, look inside the mouth; if you see the dislodged object, carefully remove it.

Important: Never perform a blind finger sweep, as probing blindly inside the throat can push an unseen foreign object further down the trachea.

7

Seek Medical Evaluation

Even after the airway is successfully cleared and normal breathing resumes, ensure the person is evaluated by a medical professional. Abdominal thrusts and chest compressions carry a risk of internal injury, such as fractured ribs or lacerations to internal organs like the spleen or liver. Additionally, microscopic food particles may have been aspirated into the lungs, increasing the risk of aspiration pneumonia.

Frequently Asked Questions

How can I perform the Heimlich maneuver on myself if I am alone?
Make a fist with one hand and place the thumb side slightly above your navel, grasp it with your other hand, and pull inward and upward. Alternatively, lean over the back of a sturdy chair, railing, or edge of a table and drive your upper abdomen forcefully against the edge.
What should I do if a choking person is in a wheelchair?
Lock the wheelchair brakes immediately. Lean the person forward to deliver five firm back blows between their shoulder blades, then reach around them from behind and perform standard abdominal thrusts, or chest thrusts if abdominal access is restricted.
Why should I avoid performing blind finger sweeps?
Sweeping blindly into the mouth can wedge a partially obstructing object deeper into the vocal cords or windpipe, turning a partial obstruction into a fatal, complete blockage, and can cause damage to delicate throat tissues.
Does a person who recovers from choking always need to see a doctor?
Yes. Forceful abdominal thrusts can cause internal bruising or organ trauma that may not be immediately apparent, and foreign material aspirated into the bronchial passages can cause delayed respiratory complications or pneumonia.
