How to Respond to Choking in Adults, Children, and Infants

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

Choking is a life-threatening emergency caused by a blocked airway that requires immediate, decisive action. This guide details age-specific first aid techniques—including back blows, abdominal thrusts, and infant chest thrusts—to clear an obstruction safely. Learn how to recognize severe airway blockage, perform rescue maneuvers, and know when to transition to CPR.

Quick Summary

Assess airway severity immediately, deliver alternating back blows and thrusts tailored to the person's age, and begin CPR if they become unresponsive.

Step-by-Step Guide

1

Recognize Signs and Assess Severity

Determine whether the airway obstruction is mild or severe. A person with a mild obstruction can still cough forcefully, speak, or make sounds; do not perform physical maneuvers, but stay with them and encourage continued coughing. A severe obstruction is marked by the universal choking sign (hands clutched to throat), silence, inability to speak or cry, weak or ineffective coughing, and blue or grayish discoloration of the lips and skin.

Important: Do not interfere with physical blows or thrusts if the person is coughing forcefully, as this can inadvertently push the foreign object deeper into the trachea.

2

Perform Back Blows and Abdominal Thrusts on Adults and Children Over 1 Year

Stand or kneel behind the person and support their chest with one hand while leaning them forward so gravity assists object removal. Deliver 5 firm back blows between the shoulder blades using the heel of your free hand. If the blockage persists, wrap your arms around their waist, form a fist with one hand placed just above the navel, grasp your fist with your other hand, and pull inward and upward with 5 quick abdominal thrusts.

Important: For pregnant individuals or those with significant obesity where you cannot wrap your arms around the abdomen, position your hands at the center of the breastbone and deliver firm, backward chest thrusts instead of abdominal thrusts.

3

Execute Back Slaps and Chest Thrusts for Infants Under 1 Year

Rest the infant facedown along your forearm, supporting their jaw and head with your hand, and rest your arm on your thigh with the infant's head positioned lower than their chest. Deliver 5 firm, distinct back slaps between the shoulder blades using the heel of your hand. If unsuccessful, turn the infant face-up along your other forearm, keeping the head lower than the body, and use 2 to 3 fingers placed at the center of the breastbone (just below the nipple line) to deliver 5 quick downward chest thrusts about 1.5 inches deep.

Important: Never perform abdominal thrusts (the Heimlich maneuver) on an infant under 1 year of age, as the anatomical fragility of their internal organs creates a severe risk of liver laceration or internal hemorrhage.

4

Repeat Rescue Cycles and Call Emergency Services

Continue alternating cycles of 5 back blows and 5 thrusts until the object is expelled and the individual can breathe normally, or until they lose consciousness. If you are with a bystander, have them call 911 immediately while you administer first aid. If you are alone with a conscious choking individual, continue the rescue cycles until the object clears or professional emergency medical services arrive.

5

Transition Immediately to CPR if the Person Becomes Unresponsive

If the person loses consciousness, gently lower them to a firm, flat surface and shout for someone to call 911 and retrieve an automated external defibrillator (AED). Begin CPR immediately starting with 30 chest compressions. Each time you open the airway to deliver rescue breaths, look inside the mouth; if you see the dislodged foreign object, carefully remove it.

Important: Never perform a blind finger sweep inside the mouth, as blindly probing the pharynx can inadvertently lodge the obstructing object deeper into the airway.

6

Seek Medical Evaluation Following Clearance

Even if the choking episode resolves and normal breathing resumes, transport the person to an emergency department for formal clinical evaluation. Abdominal thrusts and chest compressions can cause occult internal injuries, such as fractured ribs or visceral trauma, that require diagnostic imaging. In young children and infants, small fragments of the object may have been aspirated into lower bronchi, predisposing them to atelectasis, aspiration pneumonia, or delayed respiratory distress.

Frequently Asked Questions

What should I do if I am choking and completely alone?
First, dial 911 immediately, even if you cannot speak, so dispatchers can trace your location. Then, perform self-administered abdominal thrusts by placing a fist slightly above your navel, grasping it with your other hand, and thrusting inward and upward. You can also lean forward and forcefully press your upper abdomen against a firm, rigid surface, such as the back of a sturdy chair, railing, or countertop edge.
Why are blind finger sweeps strictly discouraged?
Blind finger sweeps involve probing the back of the mouth without direct visualization. This dangerous technique often acts as a piston, pushing a partially dislodged object farther down the pharynx into the vocal cords or trachea, converting a partial or retrievable blockage into a complete, fatal airway obstruction. Only grasp an object if it is clearly visible and within easy reach.
How do I distinguish between normal infant gagging and true choking?
Gagging is a normal, noisy protective reflex that infants use while learning to eat solids, characterized by loud coughing, retching, tongue thrusting, and a red face. True choking is silent or produces high-pitched wheezing, as air cannot move across the vocal cords; a choking infant cannot cry, will show signs of respiratory panic, and may rapidly develop cyanosis (bluish tint around the lips and nail beds).
Are commercial anti-choking suction devices recommended over standard first aid?
Current resuscitation guidelines from major medical authorities (such as the American Heart Association and the Red Cross) emphasize manual techniques—back blows, abdominal thrusts, and CPR—as the validated frontline standards of care. Delaying proven manual maneuvers to locate, unpack, and assemble a suction device can lead to irreversible anoxic brain injury.
