Pediatric Heimlich Maneuver Technique
For infants under 1 year old, never use abdominal thrusts (Heimlich maneuver)—instead use 5 back blows followed by 5 chest thrusts in repeated cycles; for children over 1 year old, use 5 back blows followed by 5 abdominal thrusts (Heimlich maneuver) until the obstruction clears. 1, 2, 3
Age-Based Algorithm
Infants (Under 1 Year Old)
Critical Warning: Abdominal thrusts are contraindicated in infants because they can rupture abdominal viscera. 1, 2, 4
Positioning
- Hold the infant face down (prone) along your forearm with the head lower than the trunk, supporting the head and jaw. 1, 2, 3
- The head must remain lower than the chest throughout the entire procedure to facilitate gravity-assisted expulsion of the foreign body. 2
Step-by-Step Sequence
Deliver 5 back blows: Strike firmly to the middle of the back between the shoulder blades using the heel of your hand. 1, 2, 3
Turn infant supine: Flip the infant to their back while keeping the head lower than the trunk. 1, 2
Deliver 5 chest thrusts: Place two fingers on the sternum one finger's breadth below an imaginary line joining the nipples, compress approximately 3 cm deep (one-third of the anteroposterior diameter of the chest). 1, 2
Chest thrusts should be sharper and more vigorous than CPR compressions, at approximately 20 per minute. 1, 2
Check the mouth: Look for visible foreign bodies and remove only what you can see. 1, 2, 4
Repeat the entire cycle (5 back blows + 5 chest thrusts + mouth check) until the airway clears or the infant becomes unresponsive. 2, 3, 4
Children (1 Year to Puberty)
For Conscious Children
Deliver 5 back blows first: Position the child leaning forward (across your thighs if kneeling, or bent at the waist if standing), with the head lower than the chest, and deliver 5 sharp blows to the middle of the back. 1, 3
Deliver 5 abdominal thrusts (Heimlich maneuver): Stand or kneel behind the child, make a fist and place it between the navel and xiphoid process, grasp with the other hand, and deliver 5 quick upward thrusts. 1, 3, 4
Check the mouth for visible foreign bodies after each cycle. 1, 4
Repeat alternating cycles of 5 back blows and 5 abdominal thrusts until the obstruction clears. 1, 3
For Unconscious Children
- Lay the child supine and place the heel of one hand in the middle of the upper abdomen, directed upward toward the diaphragm, delivering 5 sharp upward thrusts. 1
- If the child becomes unresponsive at any point, immediately begin CPR starting with 30 chest compressions without checking for a pulse first. 3, 4
Critical Warnings: What NEVER to Do
- Never perform blind finger sweeps in the mouth—this can push the foreign body deeper into the larynx or cause oropharyngeal injury. 1, 2, 3, 5
- Never use abdominal thrusts on infants under 1 year—risk of liver and visceral rupture. 1, 2, 3, 4
- Never hang an infant upside down by the feet—no evidence of benefit and can cause injury. 2
- Never interfere with a child who can still cough effectively—their own cough is more effective than any intervention. 3
When to Attempt Rescue Breathing
- After each cycle of back blows and chest/abdominal thrusts, if the airway remains obstructed, attempt rescue breathing. 1, 2, 4
- For infants, cover both the mouth and nose with your mouth when ventilating. 2
- Partial obstruction may allow ventilation even when complete clearance hasn't occurred. 1
Activation of Emergency Services
- Call for help immediately upon recognizing severe choking (inability to cough, speak, or breathe). 3
- If alone with an infant or small child, perform 1 minute of maneuvers first, then carry the child to the phone to activate emergency services. 1
- If someone else is present, have them call while you continue maneuvers. 2
Recognition of Severe vs. Mild Obstruction
Severe obstruction requires immediate intervention: 3
- Inability to cough or make any sound
- Universal choking sign (hands clutching throat)
- Cyanosis developing
Mild obstruction—do not interfere: 3, 4
- Child can still cough forcefully
- Can make sounds or speak
- Allow the child to clear the airway by coughing while monitoring for progression
Common Pitfalls
- Do not assume resolution means no medical evaluation is needed—foreign body aspiration can be present even without evident respiratory symptoms, and medical evaluation is mandatory. 2
- A normal chest radiograph does not rule out foreign body aspiration—clinical history takes precedence. 2
- Liquids are the most common choking cause in infants; solid foods (hot dogs, grapes, nuts, round candies) and small objects are most common in children over 1 year. 3, 6
