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. Immediate recognition and appropriate intervention can prevent brain injury and cardiac arrest. This guide outlines the life-saving steps required to assist a conscious or unconscious choking adult.

Quick Summary

Quickly alternate between 5 back blows and 5 abdominal thrusts for a conscious choking adult, and begin CPR immediately if they become unresponsive.

Step-by-Step Guide

1

Identify severe choking and assess the airway

Look for the universal choking sign of clutching the throat, a bluish tint to the lips or skin, and the inability to speak, cry, or breathe. Ask loudly, 'Are you choking?' If the person can cough forcefully or speak, encourage them to continue coughing on their own to clear the obstruction.

Important: Do not interfere with back blows or thrusts if the person is coughing forcefully, as their own coughing reflex is the most effective way to clear the airway.

2

Call emergency services

If the person cannot speak, make sound, or breathe, or if their cough is weak and ineffective, shout for help immediately. Instruct a specific bystander to call 911 (or your local emergency number) and retrieve an automated external defibrillator (AED) if available. If you are alone, proceed immediately to rescue maneuvers before stopping to call.

3

Deliver 5 firm back blows

Stand slightly behind the person to one side and support their chest with one hand. Bend the person forward at the waist so that their upper airway is roughly parallel to the ground. Using the heel of your free hand, deliver up to 5 sharp, forceful blows between their shoulder blades.

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 their 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: For individuals who are visibly pregnant or significantly obese, place your hands at the center of the chest on the lower half of the breastbone instead of the abdomen.

5

Alternate back blows and abdominal thrusts

Continue the cycle of 5 back blows followed by 5 abdominal thrusts without interruption. Stop only when the foreign object is dislodged, the person begins to cough forcefully or breathe normally, or the person becomes unresponsive.

6

Transition to CPR if the person becomes unresponsive

Gently lower the person to a flat, firm surface on their back and ensure emergency services have been dispatched. Begin chest compressions immediately, performing cycles of 30 chest compressions followed by 2 rescue breaths. Each time you open the airway to give breaths, look inside the mouth for the obstructing object.

Important: Never perform a blind finger sweep; only sweep an object out of the mouth if you can clearly see and grasp it, to avoid pushing it deeper into the airway.

7

Seek comprehensive medical evaluation

Even if the obstruction is successfully cleared, ensure the person is evaluated by a physician or emergency medical personnel. Abdominal and chest thrusts can cause internal injuries such as cracked ribs, ruptured organs, or soft-tissue damage. A clinical exam is also vital to rule out partial airway trauma or aspiration of foreign material.

Frequently Asked Questions

How do I perform first aid on myself if I am alone and choking?
Call 911 immediately and leave the line open. Make a fist, place the thumb side above your navel, grasp it with your other hand, and thrust inward and upward. Alternatively, lean over the back of a sturdy chair, counter, or railing and press your upper abdomen firmly against the edge.
Why should I avoid a blind finger sweep?
Poking a finger blindly into the back of someone's throat can push the obstructing object deeper into the larynx or trachea, converting a partial or treatable blockage into a complete, fatal airway occlusion.
Why is medical attention needed after the object is cleared?
Forceful abdominal and chest thrusts exert substantial pressure on internal anatomy and can cause rib fractures, bruising, or lacerations to organs such as the spleen or liver. Additionally, remaining particles may enter the lungs and cause aspiration pneumonia.
What is the difference between mild and severe airway obstruction?
In mild obstruction, the person can speak, cough forcefully, and breathe, and should be encouraged to cough it out without physical intervention. In severe obstruction, the person cannot make sounds, has a silent or ineffective cough, clutches their neck, and requires immediate emergency physical action.
