In a responsive adult or older child, quick inward-and-upward abdominal pressures help clear severe airway obstruction when coughing no longer works. The technique creates pressure intended to dislodge trapped food or another object, but you should stop if it comes out or the person loses responsiveness.
This guide explains first aid for a choking adult, including how to perform abdominal thrusts, when to use back blows or chest thrusts, and what to do when the person becomes unresponsive.
Airway Blockage and Its Warning Signs
A person who can cough forcefully, speak clearly, and breathe usually has a mild obstruction. You should encourage coughing, stay nearby, and avoid abdominal thrusts while the airway is still working.
Severe choking develops when an airway obstruction prevents effective coughing, speech, or breathing. Watch for a sudden inability to make sound, a weak or absent cough, silence, or a person clutching the throat.
A responsive person with any of these severe signs needs immediate assistance. Ask a bystander to call 911, or call on speaker if you’re alone, because waiting can allow the obstruction to worsen.
Choosing the Right Emergency Response
Recognizing effective coughing
A forceful cough, clear speech, and normal breathing show that the person can still move air. Encourage coughing and monitor the throat, breathing, and responsiveness. Stop the episode only when the cough becomes ineffective or you can remove a clearly visible object.
Stay close without crowding the person. You may need to act quickly when a strong cough becomes weak, speech disappears, or breathing changes. Your attention helps identify that transition before the person becomes unresponsive.
Distinguishing mild and severe choking
Mild choking permits coughing, speaking, and breathing. Severe choking limits or stops one or more of those functions, indicating that the obstruction may be blocking effective airflow.
An infant may make repeated cough sounds without producing an effective cough. Breathing, crying, and color can also help you assess an infant, so you shouldn’t rely on adult warning signs alone.
| Observed response | What it suggests | Your next action |
|---|---|---|
| Forceful cough, clear speech, and normal breathing | Mild airway obstruction | Encourage coughing, stay nearby, and monitor closely. |
| Weak or absent cough with no speech | Severe choking in a responsive person | Call 911, give back blows, and begin the trained chest or abdominal sequence. |
| Inability to breathe or ineffective infant cough sounds | Severe airway obstruction | Begin age-appropriate choking care while another person calls 911. |
| Not breathing normally or unresponsive | Severe airway and breathing failure | Lower the person safely, call 911, and begin CPR with visible-object checks. |
Use the person’s response, not the type of food involved, to determine the next action. A visible airway and normal breathing call for coughing; absent speech, ineffective cough, and breathing difficulty require the appropriate severe-choking sequence.
Understanding Back Blows, Abdominal Thrusts, and Chest Thrusts
For a responsive adult or older child with severe choking, caregivers typically alternate back blows with abdominal thrusts. The standard sequence commonly pairs 5 back blows with 5 it, checking for an expelled object between actions.
Chest thrusts provide an alternative when the abdomen cannot be used effectively. Recognized first-aid courses teach when to choose this method, so training and the emergency dispatcher’s directions should guide your response.
| Technique | Where the pressure is applied | When it may be used | Key caution |
|---|---|---|---|
| Back blows | Between the shoulder blades with the heel of the hand | First action for a responsive person with severe choking | Check after the blows and stop if the object exits or responsiveness is lost. |
| Abdominal thrusts | Soft upper abdomen above the navel and below the breastbone | Responsive older child or adult when abdominal placement is suitable | Never apply pressure to the ribs, breastbone, or lower abdomen. |
| Chest thrusts | Lower half of the breastbone for an adult; lower sternum for an infant, as taught in the course | Infants; pregnancy or another condition limiting abdominal pressure; selected cases involving obesity | Use the exact placement taught for the person’s age and body shape. |
Current guidance from the American Red Cross and American Heart Association emphasizes age-appropriate severe-choking care. Local emergency services may organize the sequence differently, so follow current training and any instructions provided by the 911 dispatcher.
Performing Abdominal Thrusts on a Responsive Adult or Child
Positioning your hands
You need correct positioning because pressure over the breastbone or ribs won’t create the intended abdominal pressure wave. Stand behind the responsive person with your feet apart for balance, then lean the person forward slightly.
Make a fist with one hand and place it above the navel but below the breastbone. Place your other hand around the fist, keeping both hands on the soft upper abdomen rather than the ribs.
Giving the thrust
The movement must be distinct enough to create a pressure wave without becoming a slow squeeze. A quick, controlled thrust directed inward and upward is more appropriate than sustained abdominal pressure.
- Create a stable stance: Stand behind the person with your feet apart and the person leaning slightly forward.
- Find the hand position: Place your fist above the navel and well below the breastbone.
- Secure the fist: Wrap your other hand around it and keep your arms slightly behind the person.
- Apply a quick thrust: Press sharply inward and upward in a controlled motion.
- Check after each action: Look for an expelled object and reassess coughing, speech, breathing, and responsiveness.
- Continue as indicated: Follow the taught cycle of 5 back blows and 5 abdominal thrusts until the obstruction clears or the person becomes unresponsive.
Don’t perform a blind finger sweep. Reach into the mouth only for an object you can clearly see and remove safely, because a blind sweep can push the obstruction farther into the airway.
A coworker taking a bite of food and suddenly losing the ability to speak demonstrates the transition from coughing to severe choking. Give the trained sequence, check after each action, and stop as soon as the food appears or your coworker goes limp.
Modifying the Technique for Specific Needs
Age and body shape determine where you place your hands. You shouldn’t apply the adult abdominal technique to an infant, and standard hand placement may not fit a pregnant person or another adult whose abdomen is difficult to reach.
Infants require back blows followed by chest thrusts rather than adult it. Recognized emergency-care courses teach the infant-specific hand placement because the anatomy and required force differ from an adult’s.
| Person or situation | Technique consideration | Key caution |
|---|---|---|
| Infant | Use infant-specific back blows and chest thrusts. | Don’t substitute it for the trained infant sequence. |
| Pregnant person | Use chest thrusts at the lower breastbone when trained. | Avoid pressure on the pregnant abdomen. |
| Adult with obesity | Consider chest thrusts when abdominal placement or force is ineffective. | Do not compensate with uncontrolled or excessive force. |
| Adult with a reachable abdomen | Use the standard soft-upper-abdomen placement. | Keep your fist above the navel and below the breastbone. |
| Adult whose abdomen is difficult to reach | Use the modified or chest-thrust method taught in your course. | Follow the dispatcher’s instructions and your training. |
Chest thrusts require precise placement rather than simply applying harder force. Different organizations may describe chest-thrust landmarks differently, so your training and the emergency dispatcher’s directions matter.
You may encounter different formats from the NHS, St John Ambulance, the European Resuscitation Council, or local emergency services. Use current local guidance rather than combining instructions from separate systems.
If those modifications still do not restore breathing, the person’s loss of responsiveness changes the response entirely.
Responding When the Person Becomes Unresponsive
A loss of responsiveness means you must stop the choking response immediately. Supporting the head and body while lowering the person onto a firm surface reduces the risk of another injury.
An unresponsive person can’t protect their airway. Once responsiveness is lost, call 911, check breathing, and begin CPR when breathing is absent or abnormal rather than continuing pressure attempts.
Lowering the person safely
Call 911 or direct a bystander to call. When you’re alone, use speakerphone so you can follow dispatcher instructions while checking breathing and starting CPR.
Open the airway by tilting the head and lifting the chin when appropriate, then look for normal chest movement. Gasping isn’t normal breathing, so begin CPR if the person remains unresponsive and isn’t breathing normally.
Checking the mouth during CPR
During CPR, rescuers open the mouth and inspect for an object that is plainly visible. Remove only an object you can see and reach safely; don’t spend valuable time on a blind search.
- Notify emergency services: Tell the dispatcher that choking occurred and the person is unresponsive.
- Start CPR promptly: Use current chest-compression and rescue-breathing guidance when breathing is absent or abnormal.
- Check before breaths: Look for a clearly visible object each time you prepare to give rescue breaths.
- Resume compressions quickly: Continue CPR when no object appears or no safe removal is possible.
- Continue until help arrives: Follow dispatcher instructions until responders take over or the person shows clear signs of life.
A person may cough or resume purposeful movement during CPR, which can indicate returning airflow. Stay with the person and arrange emergency assessment because an injury or remaining obstruction may not be obvious.
Getting Emergency Help at the Right Time
Call 911 as soon as severe choking is recognized in a responsive person. You shouldn’t wait for the person to collapse, lose consciousness, or stop breathing before requesting help.
If another adult is present, ask that person to call while you begin the appropriate choking response. If you’re alone, call 911 on speaker so emergency medical services can remain connected while you act.
Follow the dispatcher’s instructions when they conflict with your memory of a course sequence. Emergency medical services need to know the person’s condition, location, age, and whether they’re responsive, coughing, or breathing normally.
Do not leave a choking person alone unless you must obtain help immediately. A change in speech, breathing, or consciousness can occur without warning, and your next action depends on that change.
Providing Care After the Obstruction Is Cleared
An expelled object does not necessarily end the emergency. Abdominal pressure can cause internal injury, while a swallowed object or repeated forceful coughing may create another problem that requires assessment.
Keep the person seated if they’re alert and breathing comfortably. Monitor speech, breathing, skin color, chest discomfort, pain, and any return of coughing until emergency medical services take over.
Checking for complications
Severe choking can cause injury even when the airway clears quickly. Your decision about evaluation depends on symptoms such as persistent pain, breathing difficulty, chest discomfort, weakness, or a reduced level of alertness.
- Keep the person seated: Maintain a comfortable position and watch breathing, speech, skin color, and alertness.
- Arrange assessment: Seek emergency medical evaluation after a severe episode, especially if responsiveness was lost.
- Escalate breathing trouble: Call 911 for noisy breathing, blue or gray skin, chest pain, or worsening weakness.
- Watch for recurrence: Reassess the airway if coughing, voice changes, or breathing symptoms return.
- Refresh your training: Renew workplace and caregiving skills through a recognized emergency-care course.
You need emergency assessment after loss of consciousness, even if breathing returns. A persistent cough, stridor, or difficulty swallowing may indicate continued airway irritation, while abdominal or chest pain can signal injury from the rescue movements.
Recognized organizations can update the emergency-care sequence as evidence and training standards change. You can protect your household or workplace by completing an in-person course that includes choking care, CPR, and hands-on practice.
Core Steps for a Choking Emergency
The sequence depends on coughing and responsiveness: encourage an effective cough, recognize severe choking, call 911, use the correct age-specific technique, and begin CPR after responsiveness is lost.
Your first decision is whether the person can cough effectively, speak, and breathe. If those functions remain possible, support coughing; if they become ineffective, begin severe-choking care without delay.
For a responsive adult or older child, position your fist above the navel and below the breastbone. Give a quick inward-and-upward thrust, then check for an expelled object or a change in responsiveness.
Stop when the object leaves, the person becomes unresponsive, or emergency responders take over. Never continue pressure attempts after consciousness is lost because your priority shifts to airway assessment and CPR.
FAQ
What is an abdominal thrust, and what is its purpose?
An abdominal thrust is a quick, inward-and-upward pressure applied to the soft upper abdomen of a responsive adult or older child. Its purpose is to help dislodge an object causing severe airway obstruction when coughing, speech, and breathing are no longer effective.
What are abdominal thrusts and when should they be used?
it are quick inward-and-upward pressures used to help dislodge an object blocking the airway of a responsive adult or older child with severe choking. They’re appropriate when the person cannot cough effectively, speak, or breathe, and they’re commonly paired with 5 back blows in current first-aid sequences.
How do abdominal thrusts differ from back blows and chest thrusts?
Back blows use the heel of a hand between the shoulder blades, abdominal thrusts press the soft upper abdomen, and chest thrusts apply pressure to the breastbone. Chest thrusts are especially important for infants and may be used for pregnancy or selected cases involving obesity.
What signs indicate that a person has a severe airway obstruction?
Severe airway obstruction is indicated by an absent or ineffective cough, inability to speak, and difficulty or inability to breathe. A responsive person who cannot make sound or move air needs immediate help, while an unresponsive person requires CPR after the airway is opened.
How do I perform abdominal thrusts on a responsive adult or child?
Stand behind the responsive person, place your feet apart, and lean the person forward slightly. Put a fist above the navel and below the breastbone, grasp it with your other hand, and give a quick inward-and-upward thrust. Check after each action for expulsion or loss of responsiveness.
How do you perform abdominal thrusts on an adult?
That responsive adult, lean the person forward, place a fist above the navel and below the breastbone, and grasp it with your other hand. Give a quick inward-and-upward thrust, then check for expulsion or loss of responsiveness. Continue the trained sequence and follow emergency dispatcher instructions.
