Choking First Aid: Heimlich Maneuver and Infant Rescue Steps
Choking occurs when the airway becomes partially or completely blocked by a foreign object, most commonly food. According to the National Safety Council, choking is the fourth leading cause of unintentional injury death in the United States, claiming over 5,000 lives annually. Prompt recognition and correct intervention can clear the obstruction before brain damage or death occurs. This guide follows American Red Cross and American Heart Association protocols for choking emergencies across all age groups.
Recognizing Choking: The Universal Sign
The universal sign for choking is clutching the throat with one or both hands. A choking person may also be unable to speak, cry, or cough effectively. The face may turn red then blue (cyanosis) as oxygen deprivation sets in. The American Red Cross teaches that time is critical — brain damage begins within 4 to 6 minutes without oxygen.
Distinguish choking from other conditions. A person having a heart attack may clutch their chest, not their throat. Someone with anaphylaxis may have difficulty breathing but will also show signs such as hives, swelling, or a known allergen exposure. If the person can cough forcefully, speak, or breathe, encourage them to keep coughing. Do not interfere with a strong cough.
Choking Response for Adults and Children Over 1 Year
For conscious adults and children over 1 year who cannot cough, speak, or breathe, perform abdominal thrusts (the Heimlich maneuver):
- Stand behind the person and wrap your arms around their waist.
- Make a fist with one hand and place the thumb side against the person’s abdomen, slightly above the navel and well below the breastbone.
- Grasp your fist with your other hand and deliver quick, upward thrusts into the abdomen.
- Repeat thrusts until the object is expelled or the person becomes unconscious.
The Mayo Clinic cautions against applying abdominal thrusts to pregnant women or obese individuals. For these cases, use chest thrusts instead: position your fist in the middle of the breastbone and deliver backward thrusts.
Choking Response for Infants Under 1 Year
Infants require a different approach because abdominal thrusts can damage their internal organs. The American Academy of Pediatrics recommends the following sequence:
- Support the infant’s head and neck along your forearm, with the infant face-down and head lower than the chest.
- Deliver five firm back blows between the shoulder blades using the heel of your hand.
- Turn the infant face-up on your other forearm, keeping the head lower than the chest.
- Place two fingers on the center of the infant’s chest, just below the nipple line, and deliver five chest thrusts.
- Alternate between five back blows and five chest thrusts until the object is expelled or the infant becomes unconscious.
Never perform blind finger sweeps in an infant’s mouth. The CDC advises that only visible objects should be removed to avoid pushing the obstruction deeper.
Self-Administered Choking First Aid
If you are alone and choking, you can perform abdominal thrusts on yourself. Make a fist, place it above your navel, and thrust inward and upward. Alternatively, lean over a firm object such as the back of a chair, a countertop edge, or a railing, and thrust your upper abdomen against it. The American Red Cross recommends this method when no one else is available to help.
What to Do When the Person Becomes Unconscious
If the choking victim becomes unconscious, lower them gently to the floor and call 911 immediately. Begin CPR starting with chest compressions. After 30 compressions, open the mouth and look for the obstructing object. If you see it and can grasp it safely, remove it with your fingers. Then attempt two rescue breaths. If the breaths do not go in, reposition the head and try again. Continue cycles of 30 compressions, look for the object, and attempt two breaths until the object is removed or EMS arrives.
The American Heart Association emphasizes that chest compressions in CPR can create enough pressure to expel the obstruction, so high-quality CPR is both cardiac support and a choking treatment.
Choking in Elderly and Medically Vulnerable Populations
Older adults face elevated choking risk due to age-related changes. Reduced saliva production, dental issues, dysphagia (difficulty swallowing) from neurological conditions such as Parkinson’s disease or stroke, and medications that cause dry mouth all contribute to higher incidence. The National Institute on Aging advises that caregivers should serve softer foods, cut food into smaller pieces, ensure the person is seated upright during meals, and avoid rushed eating. Thickened liquids may be recommended for those with diagnosed dysphagia.
People with gastroesophageal reflux disease (GERD) or hiatal hernia may also be at increased risk because esophageal narrowing or inflammation can trap food. Anyone with a history of choking should undergo a swallowing evaluation by a speech-language pathologist.
Choking Prevention Strategies
Prevention is the most effective strategy. The National Safety Council recommends cutting food into small pieces, chewing thoroughly, avoiding talking while chewing, and supervising children during meals. High-risk foods include hot dogs, nuts, grapes, hard candy, popcorn, and chunks of meat or cheese.
Children under 4 years are at the highest risk of choking. Keep small objects such as coins, marbles, buttons, balloons, and small toy parts out of reach. The American Academy of Pediatrics advises that any object that fits through a standard toilet paper roll is a choking hazard for a young child.
For older adults, dentures, reduced saliva production, and certain neurological conditions increase choking risk. Caregivers should ensure that elderly individuals are seated upright during meals and that food is appropriately softened.
Frequently Asked Questions
Can you be choking if you can still cough? A partial blockage allows some air to pass. If the person can cough forcefully or speak, encourage them to continue coughing. Only intervene if the cough becomes weak, the person cannot speak, or they show the universal choking sign.
Should I slap someone on the back during choking? The American Red Cross does not recommend back blows for conscious choking adults because they can lodge the object deeper. For infants under 1 year, controlled back blows with the head positioned lower than the chest are the correct approach.
What if the person is pregnant or obese? Use chest thrusts instead of abdominal thrusts. Place your fist on the middle of the breastbone and pull straight back. Avoid compressing the ribs. See our CPR guide for related life-saving techniques.
How long does it take for choking to cause brain damage? Brain cells begin to die after 4 to 6 minutes without oxygen. Permanent brain damage can occur after 10 minutes. Immediate action is essential. Even if you are unsure, starting abdominal thrusts is safer than waiting.
What foods cause the most choking deaths? Hot dogs are the leading cause of choking deaths in children under 14 due to their shape and compressibility. Other high-risk foods include grapes, nuts, seeds, hard candy, and chunks of meat. Always cut hot dogs lengthwise and into small pieces for young children.
Water and Food Consistency as Risk Factors
Certain textures and shapes increase the risk of choking. Round, cylindrical foods like hot dogs and grapes can lodge in the airway and form a complete seal, making them particularly dangerous. The American Academy of Pediatrics recommends that children under 4 should not be given whole grapes, hot dogs, hard candy, nuts, seeds, popcorn, or chunks of peanut butter. Cut hot dogs lengthwise into strips rather than rounds, and quarter grapes before serving.
For older adults with dysphagia, modified texture diets are often prescribed. These range from pureed to minced and moist to soft and bite-sized. The National Dysphagia Diet provides standardized levels that healthcare facilities use to match food texture to swallowing ability. Caregivers should ensure that dietary recommendations from speech-language pathologists are followed consistently.
The Role of the Cough Reflex
The cough reflex is the body’s primary defense against airway obstruction. A forceful cough can generate air speeds of up to 100 miles per hour, sufficient to expel most foreign objects. When a person is choking and coughing effectively, do not interfere. Only intervene when the cough becomes weak, the person cannot make sound, or they show the universal choking sign.
Conditions that impair the cough reflex increase choking risk. These include neurological disorders such as stroke, Parkinson’s disease, amyotrophic lateral sclerosis (ALS), and multiple sclerosis; sedative medications, alcohol intoxication, and general anesthesia; and age-related weakening of respiratory muscles. Anyone caring for individuals with these conditions should be especially vigilant during meals.
Choking During Pregnancy
Pregnant women who are choking require modified abdominal thrusts. Perform chest thrusts instead by placing your fist on the middle of the breastbone (sternum) and pulling straight back. Alternatively, if the woman is late in pregnancy, position your hands higher on the abdomen — at the level of the lower rib cage — to avoid compressing the uterus. The American Red Cross instructs that chest thrusts are safe and effective for pregnant choking victims and cause less risk to the fetus than standard abdominal thrusts.
Conclusion
Choking emergencies escalate rapidly, but decisive action saves lives. The American Red Cross offers CPR and first aid courses that include hands-on choking training with mannequins, providing the muscle memory needed to act under pressure. Whether the victim is an adult, child, or infant, knowing the correct sequence of maneuvers — abdominal thrusts for adults and older children, back blows and chest thrusts for infants — can turn a panicked moment into a life-saving intervention. Familiarize yourself with the universal choking sign and share this knowledge with family members so everyone in your household knows how to recognize and respond to an airway obstruction.
