First Aid for a Choking Adult

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

Choking occurs when a foreign object becomes lodged in the throat or windpipe, cutting off the flow of air. Prompt recognition and rapid action are essential to prevent oxygen deprivation, loss of consciousness, and permanent injury. This guide covers how to assess a choking adult, perform back blows and abdominal thrusts, and manage the situation if the person becomes unresponsive.

Quick Summary

If a conscious adult cannot speak, cough, or breathe, alternate between five firm back blows and five abdominal thrusts (the Heimlich maneuver), calling emergency services immediately if the blockage does not clear.

Step-by-Step Guide

1

Recognize the signs and assess severity

Determine whether the airway blockage is mild or severe. Ask the person directly, 'Are you choking?' and observe if they can speak, cough, or breathe. If they can cough forcefully or speak, encourage them to keep coughing, as this is the most effective way to clear the airway.

Important: Do not interfere with forceful coughing, as administering thrusts to a person with a mild obstruction can wedge the object tighter into the airway.

2

Call emergency services

If the person cannot speak, makes high-pitched sounds, or is clutching their throat (the universal sign of choking), emergency action is required. Shout for a specific bystander to call 911 or your local emergency number and retrieve an Automated External Defibrillator (AED). If you are alone, provide immediate physical intervention first before pausing to call.

3

Deliver 5 back blows

Stand to the side and slightly behind the choking adult. Support their upper body by placing one arm across their chest and lean them forward so the object can exit rather than slide further down. Using the heel of your other hand, deliver five sharp, firm blows between their shoulder blades.

Important: Ensure the person is bent forward at the waist before delivering blows so gravity helps expel the foreign object.

4

Perform 5 abdominal thrusts

Stand directly behind the person and wrap both arms around their waist. Make a fist with one hand and place the thumb side against their abdomen, just above the navel and well below the breastbone. Grasp your fist with your other hand and pull sharply inward and upward into the abdomen five times.

Important: If the person is visibly pregnant or significantly obese, place your hands around their chest at the center of the breastbone and deliver chest thrusts instead of abdominal thrusts.

5

Alternate back blows and abdominal thrusts

Continue cycling between five back blows and five abdominal thrusts without stopping. Monitor the person continuously to see if the object has been dislodged and normal breathing has resumed. Keep repeating this cycle until the object pops out, the person can breathe or speak, or the person becomes unresponsive.

6

Begin CPR if the person loses consciousness

Carefully lower the person onto their back on a firm, flat surface if they become unresponsive. Call 911 immediately if not already done, and start chest compressions at a rate of 100 to 120 per minute. Each time you open the airway to give rescue breaths, look inside the mouth and only remove a foreign object if you can clearly see and grasp it.

Important: Never perform a blind finger sweep, as sweeping blindly can push the dislodged object deeper into the pharynx.

7

Ensure medical follow-up after the event

Even if the choking object is successfully expelled and the person feels normal, arrange for immediate medical evaluation. Abdominal thrusts exert substantial force and can lead to internal complications such as bruised ribs, lacerations of the liver or spleen, or ruptured blood vessels. An emergency physician should assess the patient for occult trauma and ensure no residual foreign material remains in the airway.

Frequently Asked Questions

How can I help myself if I am choking and alone?
Call emergency services immediately and leave the line open on speaker. Then, make a fist, place it above your navel, grasp it with your other hand, and lean over a sturdy horizontal surface (such as the back of a chair or countertop) to drive your fist inward and upward into your abdomen.
What is the difference between mild and severe choking?
In mild choking, the person can still exchange air, speak, and cough forcefully; your role is simply to encourage continued coughing. In severe choking, the airway is completely blocked, meaning the person cannot speak, breathe, or cough effectively, and requires immediate physical intervention.
Can abdominal thrusts cause serious internal injury?
Yes, abdominal thrusts can potentially fracture ribs or cause trauma to internal abdominal organs such as the spleen, liver, or stomach. Anyone who receives abdominal thrusts must undergo a medical evaluation in an emergency department, even if the blockage was resolved.
How do you help a choking adult who is in a wheelchair?
Lock the wheelchair wheels, lean the person forward over their armrest or your arm, and deliver five back blows between the shoulder blades. If the object remains lodged, stand behind the wheelchair, reach around their chest, and perform inward-and-upward chest thrusts against the lower half of the breastbone.
