Choking Emergency: Heimlich Maneuver and Infant First Aid
Choking is a life-threatening emergency that occurs when a foreign object partially or completely blocks the airway. The CDC reports that choking is the fourth leading cause of unintentional injury death in the United States, claiming approximately 5,000 lives annually. Most choking deaths occur in young children (especially under age 3), older adults, and people with neurological conditions affecting swallowing. Time is the critical factor — brain damage begins within 3 to 5 minutes of complete airway obstruction. This guide provides step-by-step protocols for managing choking in adults, children, and infants, following the most recent guidelines from the AHA, the American Red Cross, and the European Resuscitation Council.
Recognizing Choking: The Universal Sign
The first and most important step is recognizing that a person is choking. The American Red Cross teaches the universal sign of choking: one or both hands clasped to the throat. The person may also appear panicked, be unable to speak or cry, have difficulty breathing with high-pitched squeaking or stridor, cough weakly or not at all, have skin, lips, and nail beds turning blue or dusky (cyanosis), and lose consciousness if the obstruction is not relieved.
It is critical to distinguish choking from other causes of respiratory distress. A person who can cough forcefully, speak, or breathe is not completely obstructed — encourage them to continue coughing, which is the most effective way to expel a foreign body. Do not perform abdominal thrusts on someone who can cough or speak effectively. However, if the cough becomes silent or the person cannot make any sound, the airway is completely obstructed, and immediate intervention is required.
The AHA advises asking a single question: “Are you choking?” If the person nods yes but cannot speak, the airway is likely completely obstructed. Act immediately.
Adult Choking: Abdominal Thrusts (Heimlich Maneuver)
For adults and children over 1 year who are conscious and have a complete airway obstruction, the American Red Cross recommends performing abdominal thrusts — commonly called the Heimlich maneuver.
Stand behind the person and wrap your arms around their waist. Place one fist with the thumb side against the person’s abdomen, slightly above the navel and well below the xiphoid process (breastbone). Grasp your fist with your other hand. Deliver quick, upward thrusts into the abdomen — think of a “J” motion — using your entire upper body, not just your arms. Each thrust is a separate, distinct movement designed to increase intrathoracic pressure and expel the object.
Continue abdominal thrusts until the object is expelled and the person can breathe, cough, or speak, or until the person becomes unconscious. If the person loses consciousness, lower them gently to the ground and begin CPR — starting with chest compressions — as described below.
The AHA notes that abdominal thrusts can cause injury, including fractures of the ribs or xiphoid process, rupture of the stomach or esophagus, and internal organ damage. However, the alternative is death from asphyxiation. After any successful choking rescue where abdominal thrusts were used, the person should be evaluated by a healthcare provider for potential internal injury.
For pregnant or obese individuals, position your hands higher — perform chest thrusts instead of abdominal thrusts. Place your fist in the center of the sternum (breastbone) and deliver backward thrusts. The technique is otherwise identical.
Choking in Infants (Under 1 Year)
Infant choking requires a fundamentally different approach. The AHA and American Red Cross agree that abdominal thrusts should never be used on infants, as they can cause severe injury to the liver and spleen. Instead, use a combination of back blows and chest thrusts.
Hold the infant face-down along your forearm, supporting the head and jaw with your hand. Position the infant’s head lower than the chest to use gravity. Deliver 5 firm back blows between the infant’s shoulder blades using the heel of your other hand. Each blow should be of sufficient force to generate pressure that dislodges the object.
After 5 back blows, turn the infant face-up on your other forearm, keeping the head lower than the chest. Using two fingers, deliver 5 chest thrusts to the center of the chest, just below the nipple line — at the same location as infant chest compressions. Each chest thrust should compress the chest approximately 1.5 inches (4 cm).
Alternate between 5 back blows and 5 chest thrusts until the object is expelled or the infant becomes unconscious. Do not perform finger sweeps of the infant’s mouth unless you can see the object — blind finger sweeps can push the object deeper into the airway.
Choking in Children (Age 1 to 8)
Children between the ages of 1 and 8 present unique challenges in choking emergencies. Their airways are smaller than adults’ but larger than infants’, and their cognitive development means they may not be able to follow instructions or describe what is happening. The AHA recommends using abdominal thrusts for children over 1 year, but with reduced force compared with adults.
The technique is the same as the adult Heimlich maneuver, but the rescuer should kneel behind the child to bring themselves to the appropriate height. Deliver thrusts with gentler force — enough to generate airway pressure but not enough to injure the abdominal organs. If the child is very small or the rescuer is large, extreme care is needed to avoid excessive force.
Children who are choking on food are often in childcare or school settings. The CDC recommends that all childcare providers and teachers receive formal training in pediatric first aid, including age-appropriate choking management. Many states now require this training for childcare licensing. For older school-age children, the adult abdominal thrust protocol applies with full force, as their torso strength and organ protection are comparable to adults.
Self-Administered First Aid for Choking
If you are alone and choking, immediate self-help is critical. The American Red Cross provides two methods. Perform abdominal thrusts on yourself: place your fist above your navel, grasp it with your other hand, and thrust inward and upward. Alternatively, lean over a firm, fixed object — the back of a chair, a railing, or a countertop edge — and press your upper abdomen forcefully against it. Use quick, repeated thrusts until the object is expelled or help arrives.
Call 911 if possible while attempting self-thrusts — but do not delay the maneuver to make the call. If you are in a public place, signal for help using the universal choking sign.
Unconscious Choking Victim
If a choking person becomes unconscious, the American Red Cross instructs rescuers to lower the person to the ground, call 911 if not already done, and begin CPR, starting with chest compressions. This is one of the few scenarios where the standard CPR sequence is modified: after each set of compressions, open the airway and look for the object. If you see it, remove it with a finger sweep. Do not perform blind finger sweeps.
Continue the 30:2 compression-to-ventilation cycle. Each time you open the airway for rescue breaths, check if the object has been dislodged. The compressions themselves may expel the object by increasing intrathoracic pressure. In many cases, the object is not visibly expelled but becomes dislodged enough that rescue breaths can pass around it.
After a successful rescue, the person should be evaluated by a healthcare provider. Their airway may be bruised and swollen from the obstruction, and aspiration of stomach contents may have occurred during the event.
Choking Prevention Strategies
Prevention is the most effective strategy, especially for children. The American Academy of Pediatrics recommends that children under age 4 avoid certain high-risk foods: whole grapes, hot dog rounds, hard candies, nuts and seeds, chunks of peanut butter, raw carrots, popcorn, and marshmallows. Cut food into pieces no larger than one-half inch and supervise all meals.
For adults, the CDC identifies risk factors for choking: eating too quickly, talking or laughing while eating, consuming excessive alcohol before or during meals, wearing poorly fitting dentures that impair chewing, and neurological conditions (Parkinson disease, stroke, dementia) that affect swallowing.
Keep small objects — coins, buttons, marbles, batteries, pen caps, balloons, and toy parts — out of reach of young children. The CPSC Consumer Product Safety Commission tracks choking hazards and maintains a database of recalled children’s products. Balloons are a particularly dangerous choking hazard: they cause more childhood choking deaths than any other toy or product.
The WHO recommends that all caregivers of young children complete a certified first aid course that includes infant and child choking management. The first aid for children guide provides additional pediatric-specific information.
FAQ
Should I use the Heimlich maneuver on an infant?
No. Abdominal thrusts can cause severe internal injuries in infants. Use alternating back blows and chest thrusts instead. The infant’s smaller, more flexible rib cage makes this approach both safer and more effective.
Can food choking be prevented?
Many cases can be prevented by eating slowly, chewing thoroughly, avoiding talking or laughing while eating, cutting food into small pieces for children, and being cautious with alcohol consumption before meals.
What if I am alone and choking?
Perform self-administered abdominal thrusts using your fist, or lean over a firm object such as a chair back or countertop edge. Call 911 if you can do so while continuing the maneuver.
Should I stick my finger in a choking person’s mouth?
Only if you can clearly see the object. Blind finger sweeps can push the object deeper into the airway and worsen the obstruction. In an unconscious person, perform a finger sweep only if the object is visible after opening the airway.
How long does it take for brain damage to occur during choking?
Brain damage can begin within 3 to 5 minutes of complete airway obstruction. Paramedics typically arrive in 7 to 14 minutes. This is why immediate bystander intervention is essential — waiting for EMS without acting can be fatal.
