First Aid for a Choking Adult

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

Learn how to recognize and manage acute airway obstruction in an adult. This step-by-step guide covers how to assess choking severity, deliver back blows and abdominal thrusts, and transition to CPR if needed.

Quick Summary

Deliver alternating cycles of five back blows and five abdominal thrusts until the airway clears, and begin CPR immediately if the person becomes unresponsive.

Step-by-Step Guide

1

Recognize Severe Choking

Look for the universal choking sign of hands clutched to the throat, inability to speak, cyanosis around the lips, or a silent, ineffective cough. Ask the person directly, 'Are you choking?' If they can speak, cry, or cough forcefully, do not interfere physically; instead, encourage them to continue coughing to expel the obstruction on their own.

Important: Do not attempt physical interventions if the person is coughing forcefully, as this may inadvertently lodge the object deeper into the airway.

2

Call for Emergency Medical Help

Instruct a specific bystander to call 911 or your local emergency number immediately. If you are alone with the choking victim, shout for help before initiating physical maneuvers. Notify dispatch that an adult has a complete foreign body airway obstruction.

3

Deliver 5 Firm Back Blows

Stand to the side and slightly behind the choking adult. Support their chest firmly with one hand and lean the person forward at the waist so that dislodged debris can exit the mouth rather than slip further down. Using the heel of your free hand, deliver up to five sharp, distinct blows between the shoulder blades.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

Stand behind the person and wrap your arms around their waist. Form 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 lower tip of the breastbone. Grasp your fist with your other hand and pull inward and upward with quick, forceful thrusts.

5

Alternate Blows and Thrusts Until Cleared

Continue alternating between cycles of five back blows and five abdominal thrusts. Pause briefly between each maneuver to check if the foreign body has popped out or if the person has resumed normal breathing. Continue until the object is expelled or the person loses consciousness.

6

Modify for Pregnancy or Severe Obesity

If the choking individual is visibly in late pregnancy or if you cannot wrap your arms around their abdomen, use chest thrusts instead of abdominal thrusts. Position your fist over the center of their breastbone, just above the bottom of the ribs, and grasp it with your other hand. Pull straight back toward the spine with firm, rapid compressions.

Important: Do not perform abdominal thrusts on a pregnant person, as this risks blunt trauma to the uterus and developing fetus.

7

Begin CPR if the Person Becomes Unresponsive

Lower the person gently to the floor onto their back and call 911 immediately if not already done. Begin cardiopulmonary resuscitation (CPR) with 30 chest compressions, followed by opening the airway to give two rescue breaths. Each time you open the airway, look inside the mouth and remove the foreign object only if you can clearly see and reach it.

Important: Never perform a blind finger sweep, as you may push an unseen object further down into the laryngeal opening.

Frequently Asked Questions

What should I do if I am choking and completely alone?
Call 911 immediately and set your phone to speakerphone. You can perform self-administered abdominal thrusts by placing a fist slightly above your navel, grasping it with your other hand, and driving it inward and upward, or by pressing your upper abdomen firmly against the sturdy back of a chair, table edge, or railing.
Does a person who stopped choking still need to see a doctor?
Yes. Anyone who has received abdominal thrusts or experienced severe choking should undergo medical evaluation. Abdominal thrusts can cause internal injuries such as cracked ribs, punctured organs, or bruising, and residual airway inflammation or microscopic food aspiration can lead to delayed breathing complications.
How can I tell the difference between mild and severe airway obstruction?
A person with a mild obstruction can still cough forcefully, speak words, and exchange air. A person with severe obstruction cannot speak, breathes with high-pitched stridor or makes no sound at all, has a weak or silent cough, and frequently turns blue or loses consciousness.
Why is a blind finger sweep dangerous?
Poking a finger blindly into the back of someone's throat can push a partially lodged object deeper into the vocal cords, converting a partial obstruction into a complete and life-threatening blockage. Only attempt to remove an object if it is clearly visible in the front or middle of the mouth.
