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 breathing. Swift action using back blows, abdominal thrusts, and emergency resuscitation can prevent brain injury and save lives. This guide outlines how to recognize airway obstruction and provide immediate, life-saving assistance.

Quick Summary

If a conscious adult cannot speak, cough, or breathe, alternate five back blows with five abdominal thrusts until the airway is clear, and begin CPR if they become unresponsive.

Step-by-Step Guide

1

Assess Obstruction and Encourage Coughing

Check whether the obstruction is mild or severe. If the individual is coughing forcefully, speaking, or able to breathe, do not physically intervene. Encourage them to keep coughing forcefully, as spontaneous coughing is the most effective way to dislodge a foreign object.

Important: Do not deliver back blows or abdominal thrusts while the person can still cough effectively, as physical force can shift the object into a more hazardous position.

2

Recognize Severe Airway Blockage

Look for the universal sign of choking: clutching the neck with one or both hands. Severe choking is indicated by an inability to speak, silent or ineffective coughing, stridor (a high-pitched whistling sound during inhalation), or skin turning blue or pale. Ask loudly and clearly, 'Are you choking?' If they nod and cannot talk, act immediately.

3

Call for Emergency Services

Instruct a specific bystander to call 911 or the local emergency number and retrieve an automated external defibrillator (AED). If you are the only person present, immediately begin delivering first aid maneuvers. Use a mobile phone on speaker mode to connect with emergency dispatchers without pausing life-saving efforts.

4

Deliver Five Firm Back Blows

Stand to the side and slightly behind the choking person. Support their upper body by placing one arm across their chest and lean them forward at the waist so the displaced object can fall out rather than slip deeper. Deliver five distinct, firm blows between the shoulder blades using the heel of your free hand.

5

Perform Five Abdominal Thrusts (Heimlich Maneuver)

Stand directly behind the individual and wrap both arms around their waist. Make a fist with one hand and position the thumb side against the abdomen, slightly above the navel and below the breastbone. Clasp your fist with your other hand and pull sharply inward and upward in a quick motion up to five times.

Important: If the person is in the late stages of pregnancy or has severe abdominal obesity, perform chest thrusts instead by placing your fist on the center of the breastbone.

6

Alternate Cycles Until the Object Is Cleared

Repeat the cycle of five back blows followed by five abdominal thrusts without stopping. Continuously check whether the foreign body has popped out or if the person has resumed normal breathing. Cease thrusts as soon as the obstruction is dislodged or if the person loses consciousness.

7

Transition to CPR If Unresponsive

If the person collapses or loses consciousness, carefully lower them to a firm, flat surface. Call emergency services immediately if not already done, and start cardiopulmonary resuscitation (CPR), beginning with 30 chest compressions. Each time you open the airway to give rescue breaths, look inside the mouth and remove any visible object using your fingers.

Important: Never perform a blind finger sweep, as this can push an unseen object deeper into the throat and completely seal the airway.

Frequently Asked Questions

What should I do if I am choking and completely alone?
Immediately dial 911 or local emergency services and leave the line open so dispatchers can trace your location. Then, perform self-administered abdominal thrusts by placing a fist above your navel, grasping it with your other hand, and leaning forcefully over a stable horizontal edge such as the back of a chair, table, or countertop to thrust inward and upward.
Does a person who stopped choking still need to see a doctor?
Yes. Anyone who has received abdominal or chest thrusts should receive a medical evaluation. Thrusts can cause internal bruising, rib fractures, or organ trauma. A clinician must also verify that no food particles were aspirated into the lungs, which can lead to serious secondary respiratory complications.
How do chest thrusts differ from abdominal thrusts?
Chest thrusts are used for pregnant individuals or those whose waist cannot be encircled. The rescuer stands behind the person, places the thumb side of a fist on the lower half of the sternum (breastbone), grasps it with the other hand, and pulls straight back with rapid, forceful compressions.
Why are blind finger sweeps discouraged during choking emergencies?
Poking a finger blindly into the back of a victim's throat can push a lodged foreign object further down into the larynx or trachea, transforming a partial obstruction into a fatal, complete blockage. Only attempt to manually extract an object if it is clearly visible in the mouth.
