First Aid for a Choking Adult

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

Choking happens when an object or piece of food blocks the airway, preventing oxygen from reaching the lungs. Recognizing severe airway obstruction quickly and delivering immediate back blows and abdominal thrusts can save a person's life. Follow these step-by-step first aid instructions to provide emergency relief safely and effectively.

Quick Summary

Alternate between five firm back blows and five abdominal thrusts until the airway clears, or begin CPR immediately if the person becomes unresponsive.

Step-by-Step Guide

1

Assess the Severity of Choking

Quickly determine whether the airway obstruction is mild or severe. If the person can cough forcefully, speak, or breathe, encourage them to continue coughing to expel the object naturally. If they are silent, unable to breathe or cough, or clutching their throat with both hands, the 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 wedge the object deeper into the airway.

2

Call for Emergency Medical Help

Shout for help and instruct a specific bystander to call 911 or your local emergency number and retrieve an automated external defibrillator (AED). If you are alone with a conscious adult who is choking, begin physical relief maneuvers immediately before stopping to call, or activate your phone's speakerphone mode while providing aid.

3

Deliver 5 Firm Back Blows

Stand to the side and slightly behind the person. Support their upper body by placing one arm across their chest and lean them forward at the waist so that the dislodged object can exit the mouth rather than slide down the throat. Using the heel of your other hand, deliver up to five sharp, distinct blows between their shoulder blades.

4

Perform 5 Abdominal Thrusts (Heimlich Maneuver)

If back blows do not clear the airway, stand behind the person and wrap your arms around their waist. Make a fist with one hand and place the thumb side against their abdomen, slightly above the navel and well below the lower tip of the breastbone. Grasp your fist with your other hand and pull sharply inward and upward up to five times.

Important: Never position your hands directly over the ribs or the xiphoid process (the bottom tip of the breastbone) to avoid internal organ damage or rib fractures.

5

Modify Technique for Pregnancy or Obesity

If the choking individual is in the later stages of pregnancy or is too large to encircle at the waist, use chest thrusts instead of abdominal thrusts. Position your fist over the center of their chest at the lower half of the breastbone, cover it with your other hand, and pull straight back with rapid, forceful thrusts.

6

Continue the 5-and-5 Cycle

Repeat the cycle of five back blows followed by five abdominal (or chest) thrusts without stopping. Continue this sequence until the foreign object is expelled, the person can breathe or speak, or the person loses consciousness.

7

Transition to CPR if the Person Collapses

If the person becomes unresponsive, gently lower them to their back on a firm, flat surface and alert emergency dispatch immediately. Begin CPR starting with 30 chest compressions; each time you open the airway to give rescue breaths, look inside the mouth and remove the foreign object only if it is clearly visible.

Important: Never perform a blind finger sweep inside the mouth, as you risk pushing the object deeper into the windpipe.

Frequently Asked Questions

What should I do if I start choking and I am completely alone?
Call emergency services immediately and leave the line open. You can perform abdominal thrusts on yourself by placing a fist slightly above your navel, grasping it with your other hand, and thrusting inward and upward, or by pressing your upper abdomen firmly against the back of a sturdy chair, railing, or edge of a counter.
Does a person need to see a doctor after the choking object is cleared?
Yes. Anyone who has received abdominal or chest thrusts should be medically evaluated promptly. The forceful maneuvers can cause occult internal trauma, including fractured ribs, abdominal wall hematomas, or lacerations to organs such as the spleen, liver, or stomach.
Why are blind finger sweeps no longer recommended?
Blind finger sweeps involve probing the back of the mouth without seeing the obstruction. This technique frequently forces a dislodged object further down into the laryngeal inlet, converting a partial or retrievable blockage into a complete, fatal airway occlusion.
How can I tell the difference between a partial and complete airway blockage?
A person with a partial blockage can still exchange some air, speak in hoarse whispers, wheeze, or cough forcefully. A person with a complete blockage cannot make any vocal sounds, cannot cough, struggles frantically for breath, and may rapidly turn blue or pale from acute lack of oxygen.
