First Aid for a Choking Adult

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

Choking occurs when a foreign object blocks the airway, preventing normal breathing and vocalization. Prompt recognition and immediate first-aid intervention can save a life before emergency personnel arrive. This guide outlines standard protocols for assisting a conscious or unconscious choking adult.

Quick Summary

Alternate five firm back blows with five abdominal thrusts until the airway is cleared, and begin CPR immediately if the person loses consciousness.

Step-by-Step Guide

1

Recognize the Signs and Assess the Airway

Check for universal signs of choking, such as clutching the throat, an inability to speak or cry out, high-pitched wheezing, or facial discoloration. Ask the person directly, 'Are you choking?' If they can cough forcefully or speak, encourage them to keep coughing to clear the airway on their own.

Important: Do not interfere with back blows or abdominal thrusts if the person is coughing forcefully, as spontaneous coughing is the most effective way to dislodge an obstruction.

2

Call Emergency Services

If the person cannot speak, breathe, or cough effectively, immediate medical intervention is critical. Designate a specific bystander to call 911 (or your local emergency number) and retrieve an Automated External Defibrillator (AED) if available. If you are alone, deliver initial life-saving measures immediately before pausing to call.

3

Deliver 5 Back Blows

Stand to the side and slightly behind the choking adult. Support their chest with one arm and bend them forward at the waist so that the dislodged object can exit the mouth rather than slip further down the throat. Deliver up to five distinct, firm blows between their shoulder blades using the heel of your hand.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

Stand behind the person and wrap your arms around their waist. Make a fist with one hand and place the thumb side against the middle of the person's abdomen, just above the navel and well below the breastbone. Grasp your fist with your other hand and press inward and upward with quick, forceful thrusts.

Important: Avoid placing your hands directly on the lower tip of the breastbone (xiphoid process) or ribs to prevent internal injuries and fractures.

5

Adapt Technique for Pregnancy or Obesity

If the person is visibly pregnant or has a large body habitus that prevents you from wrapping your arms around their abdomen, position your hands higher on the chest. Place the thumb side of your fist against the center of their breastbone (sternum). Grasp your fist with your other hand and deliver quick, backward chest thrusts instead of abdominal thrusts.

6

Repeat the Cycle Until Relieved

Continue alternating cycles of five back blows and five abdominal (or chest) thrusts without stopping. Monitor the individual closely to see if the foreign body is expelled and normal breathing resumes. Maintain this sequence until the airway is clear or the person becomes unresponsive.

7

Begin CPR if the Person Becomes Unresponsive

Carefully lower the person onto their back on a firm, flat surface and shout for someone to ensure emergency services have been contacted. Begin cycles of 30 chest compressions followed by 2 rescue breaths. Each time you open the airway to deliver breaths, inspect the mouth; if you see the obstructing object, carefully remove it with your fingers.

Important: Never perform a blind finger sweep, as this can push an unseen object deeper into the airway.

Frequently Asked Questions

Can I perform abdominal thrusts on myself if I am alone and choking?
Yes. Place a fist slightly above your navel, grasp it with your other hand, and thrust inward and upward. Alternatively, lean over the back of a sturdy chair, railing, or countertop and drive your abdomen against the edge to force air upward.
Should someone visit the hospital after choking has been successfully resolved?
Yes. Anyone who has received abdominal thrusts, chest thrusts, or CPR should be evaluated by a physician to rule out internal injuries, broken ribs, or lingering airway complications.
What is the difference between mild and severe choking?
Mild choking involves a partially blocked airway where the person can still talk, cough loudly, and breathe, requiring only monitoring and encouragement to cough. Severe choking involves complete obstruction where the person cannot speak, breath, or cough, requiring immediate physical intervention.
Why is a blind finger sweep discouraged?
Sweeping your finger through the mouth without seeing an object can push the lodged item further down into the trachea or cause injury to the soft tissues of the throat. Only remove an item if it is clearly visible and within reach.
