First Aid for a Choking Adult

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

Choking is a life-threatening medical emergency caused by a foreign object blocking the airway. Recognizing the universal sign of choking and acting swiftly with back blows and abdominal thrusts can restore normal breathing within seconds. Follow these evidence-based first-aid steps to assist a conscious or unresponsive choking adult safely.

Quick Summary

If a choking adult cannot cough or speak, alternate five back blows with five abdominal thrusts until the airway clears or they become unresponsive.

Step-by-Step Guide

1

Assess Obstruction Severity and Encourage Coughing

Quickly determine whether the airway obstruction is mild or severe. If the person can speak, answer questions, or cough forcefully, their airway is only partially blocked; encourage them to keep coughing vigorously to dislodge the object. If they cannot speak, are clutching their neck with both hands, make high-pitched wheezing noises, or are turning cyanotic (blue), treat it immediately as a complete obstruction.

Important: Do not deliver back blows or thrusts if the person is coughing forcefully, as physical intervention may shift the object and cause a complete blockage.

2

Activate Emergency Services

Shout for help immediately if the victim displays signs of severe choking. Direct a specific bystander to call 911 (or local emergency dispatch) and retrieve an automated external defibrillator (AED). If you are alone with the victim, begin physical clearance maneuvers immediately without delay.

3

Deliver Five Back Blows

Position yourself slightly behind and to the side of the choking person. Support their upper chest with one hand and bend them forward at the waist so their airway is angled downward, helping gravity expel the object. Use the heel of your dominant hand to deliver up to five firm, distinct blows directly between their shoulder blades.

4

Perform Five Abdominal Thrusts

If back blows fail to clear the blockage, stand directly behind the person and wrap your arms around their waist. Make a fist with one hand and place the thumb side flat against their abdomen, just above the navel and well below the xiphoid process (breastbone tip). Grasp your fist with your other hand and pull sharply inward and upward into the abdomen up to five times.

Important: For visibly pregnant women or individuals who are severely obese, substitute abdominal thrusts with chest thrusts delivered over the center of the breastbone.

5

Alternate Cycles Until Relieved

Continue alternating cycles of five back blows and five abdominal thrusts without stopping. Pause briefly between individual thrusts to check if the lodged foreign body has popped out. Cease maneuvers immediately once the foreign object is expelled and the individual resumes normal, unhindered breathing.

6

Transition to CPR if the Person Becomes Unresponsive

If the individual loses consciousness, carefully support them and lower them flat onto their back on a firm, level surface. Call 911 immediately if not already done, and begin cardiopulmonary resuscitation (CPR) starting with 30 chest compressions. Each time you open the airway to administer two rescue breaths, inspect the mouth; only remove an object if it is clearly visible and loose.

Important: Never perform a blind finger sweep, as probing blindly can push a lodged foreign object deeper into the laryngeal airway.

7

Seek Post-Choking Medical Evaluation

Anyone who has experienced a severe choking episode or received abdominal thrusts must be evaluated by a healthcare professional at an emergency department or urgent care facility. Abdominal thrusts can cause internal trauma, such as bruised or ruptured abdominal organs, fractured ribs, or diaphragm injuries. Medical evaluation also ensures no residual food or liquid has aspirated into the lungs, which could cause chemical pneumonitis or bacterial pneumonia.

Frequently Asked Questions

What should I do if I am alone and choking?
If you are alone and choking, immediately dial 911 and leave the line open so emergency services can trace your location. Then, perform self-administered abdominal thrusts by placing a fist above your navel, grasping it with your other hand, and thrusting inward and upward. Alternatively, press your upper abdomen firmly against the back of a sturdy chair, railing, or edge of a countertop to force air out of your lungs.
Why are blind finger sweeps dangerous?
Blind finger sweeps involve sweeping a finger through the victim's mouth without seeing the obstruction. This dangerous practice can inadvertently push the foreign object further back into the pharynx or vocal cords, transforming a removable obstruction into a complete and fatal airway blockage.
How do abdominal thrusts dislodge an obstruction?
Abdominal thrusts work by suddenly elevating the diaphragm and compressing the lungs from below. This rapid increase in intrathoracic pressure forces residual air from the lungs up through the trachea, creating an artificial cough strong enough to propel the foreign object outward.
How do I perform chest thrusts on a pregnant or obese adult?
Stand directly behind the individual and wrap your arms underneath their armpits across their chest. Place the thumb side of your fist against the center of their breastbone (sternum), just above where the lower ribs meet, cover your fist with your other hand, and deliver rapid, straight-back thrusts into the chest until the object is expelled.
