First Aid for a Choking Adult

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

Choking occurs when a foreign object lodges in the throat or windpipe, cutting off vital airflow. Recognizing the signs of severe airway obstruction and acting swiftly can prevent brain damage or cardiac arrest within minutes. This guide outlines the immediate life-saving techniques required, including back blows, abdominal thrusts, and emergency resuscitation.

Quick Summary

If a conscious adult cannot speak, cough, or breathe, alternate five firm back blows with five rapid abdominal thrusts until the airway is clear or the person becomes unresponsive.

Step-by-Step Guide

1

Assess Obstruction Severity and Encourage Coughing

Quickly ask the person, 'Are you choking?' and check if they can speak, groan, or cough forcefully. If they can cough forcefully and breathe adequately, do not physically intervene; encourage them to keep coughing to dislodge the object on their own. If they can only nod, cannot make sound, are wheezing weakly, or are clutching their throat, the airway is severely obstructed and requires immediate physical intervention.

Important: Do not deliver back blows or thrusts if the person is coughing forcefully, as physical impact can dislodge the foreign body deeper into the trachea.

2

Call Emergency Services Immediately

Direct a specific bystander to call 911 (or your local emergency response number) and retrieve an automated external defibrillator (AED) if available. If you are entirely alone with the person, shout loudly for help while immediately beginning rescue maneuvers. You can place your mobile phone on speakerphone next to you to speak with dispatchers without delaying physical care.

3

Deliver 5 Firm Back Blows

Stand to the side and slightly behind the choking adult. Support their upper torso by placing one hand firmly across their chest and lean them forward at the waist so that gravity helps dislodge the object outward through the mouth. Using the heel of your other hand, deliver up to five sharp, distinct blows directly between the person's shoulder blades. Check after each blow to see if the blockage has cleared.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

If back blows do not clear the airway, stand directly behind the person and wrap your arms around their waist. Make a tight fist with one hand and place the thumb side against the middle of their abdomen, slightly above the navel and well below the breastbone. Grasp your fist firmly with your other hand and deliver up to five quick, upward and inward abdominal thrusts to force trapped air up from the lungs.

Important: Never position your hands over the ribs or the bottom tip of the breastbone (xiphoid process), as forceful pressure can fracture bones or rupture internal organs.

5

Alternate Cycles Until the Airway Clears

Continue alternating between five back blows and five abdominal thrusts in continuous cycles. Stop immediately if the foreign object pops out, if the person resumes normal breathing, or if they speak or cough effectively. Monitor the person continuously, as residual airway swelling or partial obstruction can still cause respiratory compromise.

6

Modify Technique for Pregnancy or Severe Obesity

If the choking adult is visibly pregnant or you cannot wrap your arms fully around their abdomen, switch from abdominal thrusts to chest thrusts. Position yourself behind the person and place your arms directly under their armpits. Position the thumb side of your fist on the center of their breastbone (sternum), grasp your fist with your other hand, and pull straight back with rapid, forceful thrusts.

7

Transition to CPR if the Person Becomes Unresponsive

If the person loses consciousness at any point, gently support their body to lower them flat onto their back on a hard, level surface. Immediately start CPR with 30 chest compressions, pushing hard and fast in the center of the chest. Each time you open the airway to give rescue breaths, look inside the mouth; if you clearly see the foreign object, remove it. Continue CPR cycles of 30 compressions and 2 breaths until emergency medical personnel take over.

Important: Never perform a blind finger sweep inside the mouth, as poking blindly can push a lodged foreign object further down into the larynx or trachea.

Frequently Asked Questions

What should I do if I am choking and completely alone?
Immediately call 911 and leave the phone line open so dispatchers can trace your address. You can perform self-thrusts by placing a fist slightly above your navel, grasping it with your other hand, and thrusting inward and upward, or by firmly leaning forward and thrusting your upper abdomen against the rounded back of a chair, table edge, or railing.
Does a person who stops choking still need to go to the hospital?
Yes. Anyone who has received abdominal thrusts, chest thrusts, or back blows must be evaluated by a physician. These forceful maneuvers can cause occult internal injuries, such as bruised organs, ruptured vessels, or rib fractures, and microscopic foreign matter may remain inhaled in the lungs.
Why do some protocols recommend back blows while others recommend only abdominal thrusts?
Different professional organizations emphasize slightly different approaches based on regional guidelines. The American Red Cross and the UK Resuscitation Council advise alternating five back blows with five abdominal thrusts ('five-and-five'), whereas the American Heart Association focuses primarily on continuous abdominal thrusts for conscious adults. Both methods are clinically accepted, evidence-based ways to expel an airway blockage.
How can I tell the difference between mild and severe choking?
In mild choking, the airway is only partially occluded; the person can still speak, make sounds, and cough forcefully. In severe choking, the airway is entirely or nearly entirely closed; the person cannot speak or cough, cannot draw in air, may make high-pitched squeaking sounds, and typically clutches their throat in distress.
