First Aid for a Choking Adult

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

Choking is a medical emergency that occurs when a foreign object blocks the airway, preventing normal airflow and oxygenation. Acting immediately with alternating back blows and abdominal thrusts can rapidly dislodge the obstruction and save a life. Knowing these first aid steps allows you to respond effectively whether the individual remains conscious or collapses.

Quick Summary

Alternate five sharp back blows with five abdominal thrusts to clear the airway, and begin CPR immediately if the person becomes unresponsive.

Step-by-Step Guide

1

Assess the Severity of the Obstruction

Ask the person, 'Are you choking?' and determine if they can speak, cough, or breathe. If they are coughing forcefully and able to speak, the airway is only partially blocked; encourage them to keep coughing and monitor them closely. If they cannot speak, are clutching their throat, making high-pitched squeaking sounds, or turning blue, their airway is severely blocked and requires immediate intervention.

Important: Do not deliver back blows or thrusts if the person is coughing forcefully, as physical intervention may lodge the object deeper into the airway.

2

Call for Emergency Medical Services

Instruct a bystander to call 911 or your local emergency number and retrieve an automated external defibrillator (AED) immediately. If you are alone with the conscious choking adult, provide physical first aid right away before stopping to make the phone call yourself. Directing a specific person to make the call prevents confusion and ensures emergency responders are en route.

3

Administer 5 Sharp Back Blows

Stand to the side and slightly behind the choking adult. Place one arm across their chest for support and lean them forward at the waist so that the dislodged object can exit the mouth rather than slipping further down the throat. Use the heel of your other hand to deliver five distinct, forceful blows between the person's shoulder blades.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

Stand behind the person and wrap both arms around their waist. Make a fist with one hand and place the thumb side against the middle of their abdomen, slightly above the navel and well below the lower tip of the breastbone. Grasp your fist firmly with your other hand and deliver five quick, inward-and-upward thrusts into the abdomen.

Important: Do not perform abdominal thrusts on a woman in the late stages of pregnancy or on an individual with severe obesity; perform chest thrusts instead.

5

Alternate Cycles of Back Blows and Thrusts

Continue alternating between five back blows and five abdominal thrusts without stopping. Pause briefly between each maneuver to check if the foreign object has dislodged and the person can breathe again. Continue this cycle until the object is expelled, the person begins coughing forcefully or breathing, or the person becomes unresponsive.

6

Modify Technique for Pregnancy or Obesity

If you cannot reach around the person's waist due to pregnancy or obesity, position your hands over their chest instead of their abdomen. Stand behind them, place the thumb side of your fist against the center of their breastbone (sternum) at armpit level, and grasp your fist with your other hand. Pull straight back toward yourself with quick, firm chest thrusts, alternating with back blows.

7

Transition to CPR if the Person Collapses

If the individual loses consciousness, ease them carefully to the ground onto their back, protecting their head. Ensure 911 has been contacted, then begin cardiopulmonary resuscitation (CPR) starting with 30 chest compressions. Each time you open the airway to deliver two rescue breaths, look inside the mouth; if you see the obstructing object, carefully remove it with your fingers.

Important: Never perform a blind finger sweep, as probing the mouth without seeing the object can push it further down the throat.

Frequently Asked Questions

What should I do if I am choking and completely alone?
Call emergency services immediately, put the phone on speaker, and leave the line open. You can perform self-administered abdominal thrusts by placing a fist above your navel, grasping it with your other hand, and pulling inward and upward, or by firmly leaning forward and thrusting your upper abdomen against the back of a sturdy chair, railing, or table edge.
Why is a blind finger sweep dangerous?
A blind finger sweep involves sweeping a finger through the mouth or throat without visually confirming the object's location. This carries a high risk of pushing the foreign body deeper into the trachea, converting a partial blockage into a complete obstruction, or lacerating delicate oral tissues.
Does someone who stops choking still need to see a doctor?
Yes. Anyone who has received abdominal or chest thrusts should be medically evaluated. The force required to clear an airway obstruction can occasionally cause internal complications, such as fractured ribs, organ bruising, or lacerations, and inhaled food particles can lead to subsequent pulmonary infections.
What is the universal sign of choking?
The universal sign is an individual clutching their throat with one or both hands. This nonverbal signal usually accompanies an inability to speak, an expression of panic, ineffective coughing, and rapid progression toward a bluish or pale skin tone.
